10 Safety Instructions to Follow When Handling Battery Packs

by Alexander J.
written by Alexander J.

Batteries have become a part of our day to day activities. The most preferred are the lithium-ion batteries such as the 18650 Battery, due to their high energy density. The batteries packs come in different models, each with a specific set of features and benefits; they also have a wide range of applications thanks to their low self-discharge as well as their lifetime in cycling.

The user ought to be cautious when using the battery packs to ensure that the application troubles do not affect them. The batteries contain cells that have organic solvents that are highly flammable. In the event that the battery is not handled with precaution, the battery’s functionality will be affected and it could result in fires.

Safety Instructions for battery packs

Some of the major forbidden activities include:

  • Use of unauthorized chargers

Never use unauthorized chargers. Only charge the battery under acceptable conditions as specified in the manual.

  • Unspecified Application

Do not use the battery for any other purpose other than that which it’s specified for. Using the battery for unspecified applications may damage the battery and cause it to explode.

  • Direct Connection

Don’t connect the battery directly with car or AC plugs. Connecting to the outlet directly may cause accidents.

  • Immersion

Do not, in any instance, immerse the battery with liquids like water or other soft drinks. This will result in an unexpected electrical load and cause the battery pack to catch fire.

  • Incineration and heat

Keep the battery away from heat and fire. If it’s exposed to too much heat or catches a fire, the battery may explode.

Never use the battery in environments where temperatures exceed 80°C. The high temperatures could damage the battery’s polyolefin separator and causing internal shorting.

  • Short-circuiting

A short-circuit is made when you connect the “+” and the “-” terminals together using a material that conducts electricity. Avoid doing this as it may cause an excessively large current to flow through and this could result in an explosion.
Short circuiting battery pack

  • Soldering

If you directly soldier the battery, the heat will damage the gas release vent and melt the insulator.

  • Disassembly and reconstruction

When you disassemble the battery, there’s a high chance that the protection circuit will get damaged. When this happens, the battery will not be protected anymore and it will easily get damaged.

  • Impact and penetrations

Avoid unnecessary impact such as striking the battery with a hammer or penetrating it with a nail. These actions will damage the battery cell and break the protection circuit which will cause internal shorting.

  • Reverse charging and overcharging

As you charge the battery ensure that you don’t reverse-charge it as this will result in an abnormal chemical reaction. During discharge, a large unexpected current will flow.

Ideal Storage Conditions for Battery packs

If the storage is for a short duration (about 3months), make sure the room has low humidity, ambient temperature (-20 to +40°C), and doesn’t have corrosive gases.

If you’re storing the batteries for a longer duration, find a more stable environment that will not minimize the risk of rusting. The ideal temperature should range between -20 to +20°C. The battery should also be partially charged.

Get the perfect electric drill using these hacks

by Alexander J.
written by Alexander J.

Like all industrial tools, getting the perfect electric drill can prove to be a real task. While there are reputable companies such as Inno Manufacturing Company; an OEM manufacturing based in Shenzhen, China; where you are guaranteed to get the best quality of products, there are also some rip offs who seek to take advantage of your naivety and sell you inferior electric drills for discounted, or even inflated prices. However, with the tips I am about to give you, you don’t have to worry about being ripped off as after reading this article, you won’t be a naïve mind ripe for the taking anymore.

What to Look Out For When Buying an Electric Drill

If you go to a website that sells electric drills, before you proceed to purchase the drill of your choice, be sure to consider and check for the following:

drill

  • Speed Of The Drill

Before purchasing a drill, you should have in the back of your mind the purpose for purchasing it. Do you need it to drive in screws, or you need it to drill in holes? Which of them are you going to be doing more? The answers to these questions will largely determine the speed of your ideal drill.

Most electric drills come with two speed settings: 300 rpm and 800 rpm, with a switch that lets you alternate between both speeds. If you’re going to screwing in more nails than drilling holes, this should be ideal for you. However, if you are going to be carrying out a lot of hole drilling compared to screws driving, you might want to opt for an electric drill with a higher speed range.

  • Capacity Of The Battery

As it is with any gadget, the battery capacity of an electric drill is of utmost importance. Your drill’s battery’s capacity has the power to make or break or your work as you might need extra days to complete a job that would have taken you a day if your electric drill had a powerful battery.

Ensure that the battery has a high Ah (Amp hours) power and a powerful charger capable of charging the battery effectively without damaging it.

1

Hints:

  • NiMH (Nickel-metal-hydride) batteries are better than NiCad (Nickel-Cadmium) batteries.
  • The fact that your battery has a fast charge time doesn’t mean it is going to last longer. Only the Ah can guarantee that.
  • Ensure to get quality and smart chargers. Subpar chargers may end up damaging the battery of the electric drill
  • It doesn’t hurt to have an extra battery.

  1. Power/Voltage

The perfect drill to carry out your work also depends on the type of job you wish to carry out and the power required to get it done. Are you going to driving in screws only? Then an electric drill with 6V or 7.2V should be perfect for you. Are you going to be carrying out heavy duty jobs? You should totally get a drill of say 14.4V or 18V.

If you’re going to be carrying out both light and heavy duty jobs simultaneously, you should go for a drill with an average voltage i.e. 9.6V or 12V

N.B. The higher the voltage, the higher the weight of the electric drill.

 

Getting the perfect industrial electric drill can be real hard, but with the help of the above tips, it should be a cake walk.

Pros and Cons : 3D Printing VS CNC Machining

by Alexander J.
written by Alexander J.

 

There are numerous printers that carry out 3d printing. While they may utilize varying materials and technologies, they all operate in a similar way i.e. begin from scratch before proceeding to form a three dimensional object layer by layer. This process is known as additive manufacturing.

mnThe use of 3D printers is becoming popular as it offers lots of benefits the traditional manufacturing techniques do not. In spite of this, 3D printing comes with its own shortcomings. These shortcomings include the fact that once mass production is involved, 3D printers cannot be effectively used to carry out the job, and the fact that 3D printing is limited in accessibility and speed.

CNC (Computer Numerical Control) milling machines on the other hand utilizes cutters or sharp rotating tools to rid a block of concrete material (wood or aluminum) of parts that are not of importance or surplus to requirements. This process which is the complete opposite of the additive method used by 3D printers is known as subtractive method.

CNC machines are controlled by computers which gives them some machine-specific and particular codes to control the sharp rotating tools or cutters. The models of CNC machines are manufactured by making use of a 3D modeling software known as Computer-Aided Manufacturing (CAM) software applications.

The main difference between 3D printers and CNC machines is the fact that they both make use of different types of manufacturing.

As stated earlier, 3D printers make use of additive manufacturing where objects are created layer by layer till it is fully built. 3D printing makes use of materials like resins, plastic powders, and plastic filaments. One advantage of additive manufacturing is that it gives the object freedom of shape.

mnnn

CNC machines on the other hand makes use of subtractive manufacturing where cutters are used to chip parts off a block until the desired shape of the object is achieved. One advantage of this method is that it can be used with a ton of materials such as metals, wood, and plastic.

Knowing how the two prototyping machines work, it is only right we compare and contrast the two in order to determine which one of them is the best to be used in the manufacturing of prototypes.

Choice of materials

As far as materials go, 3D printers have limited reach. This means that 3D printers can only make use of a few materials, usually resins or thermoplastics. A 3D printer that can handle thermoplastics will not be able to handle resins. This is because they both make use of totally different methods.

CNC machines are compatible with a large number of materials such as acrylic, metal alloys, hardwoods, softwoods, machining wax, modeling foams, thermoplastics, etc. while you may be needing varying cutting tools for varying materials, it isn’t something to be worried about as the tools can be exchanged effortlessly thanks to the standardized interfaces.

Speed

It may be hard to compare the speed of the two machines as they are used for different objects and with varying materials. However, CNC machineries do not usually take more than 1 hour to get the job done while 3D printers usually require hours to complete their jobs.

mnn

In other words, CNC machining has a faster speed than 3D printing where the objects are built layer by layer.

Noise and vibrations

The noise that comes from 3D printers during usage sounds like a gentle breeze while that of CNC machines can be so loud it could deafen your ears. Although, the extent of the noise coming from the CNC machines largely depends on what material you are cutting. The noise it gives when cutting wax models can barely be heard while the one it gives when cutting wood or metal is the ultimate ear blocker

As far as vibrations go, you need not worry about it while using a 3D printer, however, while making use of CNC machines, it is probably best if you don’t place it on a table close to you due to the rate at which it vibrates. In the same veil of the kind of noise it gives, the level of vibration GNC machines gives depends on the type of material being used.

 

Cost price

The cost of both machines is pretty hard to compare, although at the initial stage, 3D printers are much cheaper in the initial stages than CNC machines. You could get a decent 3D printer for as low as $500 while CNC machining starts at $2000.

However, as time goes on, if you make use of a high quantity of parts, CNC machines prove to be cheaper. All in all, in the initial stages, and if you are going to be producing in low volumes, 3D printers are cheaper. However, if you are going to produce in large quantities, CNC machining will be better off.

What to buy?

This is a tricky question that cannot be answered out rightly. This is because each machine have their strong suit and areas in which they thrive. So, for certain prototypes, a 3D printer will be the preferred option while for other prototypes, CNC machining will be best.

If you are a maker that works on different type of prototypes, it will be best and to your own benefit if you purchase both machines.

Importance of Rapid Prototyping in Automotive Industry

by Alexander J.
written by Alexander J.

Fast prototyping is programmed to develop physical items by utilizing added substance fabricating innovations. Added substance fabrication is currently the principal challenger to the three customary metrics for manufacture:

  • Subtractive- cutting material away, as in stone apparatus making and present day machining
  • Shaping- Earthenware, throwing and forming
  • Framing- Twisting, fashioning and stamping.

Prototyping Today

The expansiveness of rapid prototyping procedures is minimal. Everything from LOM and 3D printing, through to particular laser sintering, stereolithography and EBM are currently generally acknowledged methods. Every innovation overly seeks a piece of the industry relying upon elements like material, quality necessities, amounts and cost.

prototyping1

Fundamentals of Rapid Prototyping

The fundamental goal of car prototyping is to rapidly figure out how another car item carries on in its characteristic workplace, before exchanging the model to the creation line. Therefore, choosing an appropriate RP process for the activity is essential. Moreover, Tier one car provider, Dana Corporation exhibits the best practice.

Dana has discovered that its Fortus framework exceeds expectations at influencing precise fast models of convoluted gatherings to like grip congregations. Indeed, FDM models are strong to the point that sometimes they even utilize the models to help assess the execution of the part.

Fused Deposit Modeling

Fused Deposit Modeling handles added substance standards. It sets down material in layers. A plastic fiber or metal wire is loosened up from a loop and supplies material to an expulsion spout which can kill the stream on and.

The spout is warmed to liquefy the material and can be moved in both flat and vertical bearings by CNC, controlled specifically by CAM programming. The model or part is delivered by expelling little globules of thermoplastic material to frame layers as the material solidifies promptly after expulsion from the spout.

Applications of Fused Deposit Modeling

  1. Vehicle outline prototyping

A BMW plant in Regensburg, Germany implores FDM as an imperative segment in vehicle outline prototyping. The plant’s branch of installations utilizes a Stratasys 3D generation framework to manufacture hand devices for vehicle gathering and testing.

prototyping

Engineers have found that there are incredible favorable circumstances that emerge from the outline flexibility that FDM offers. Take BMW for instance. It opts to decrease the heaviness of a gadget by 72% with a scanty fill construct procedure. Supplanting the strong center with inner ribs cut 1.3kg from the gadget. This may not seem like much but when a laborer utilizes the apparatus several times in a move, it has a major effect.

Advantages of FDM

  1. Enhanced usefulness.

Since the added substance process can without much of a stretch deliver natural shapes that range and stream, apparatus originators can boost execution while enhancing deals with qualities.

An illustration is an apparatus made for connecting guard underpins, which includes a convoluted tube that curves around blocks and places installation magnets precisely where required.

Testing existing known limits with Rapid Prototyping

You are able to run with RP strategies such as FDM for little parts. In a noteworthy propel, the Stratasys improvement association with Winnipeg designing gathering, Kor Ecologic will see it make one of the world’s most fuel-proficient and ecologically benevolent vehicles.

Code-named Urbee, it is the main auto ever to have its whole body delivered by added substance fabricating forms – the principal full-scale model showed up at the SEMA display in Las Vegas in November a year ago.  

prototyping5

Urbee is the main model auto ever to have its whole body 3D-printed with an added substance process. Every single outside part – including the glass board models – were made utilizing Dimension 3D printers and Fortus 3D creation frameworks at Stratasys’ computerized producing administration.

In any case, motor segments are at present not normal as they need to withstand high temperature and mechanical pressure. Be that as it may, this is changing and innovation specialists, for example, ProtoCAM have been utilizing thermoset phenolic materials to make motor parts for various years as the material is solid and has phenomenal warmth obstruction.

Material world and Selective Laser Sintering

All things considered, contrasted with different strategies for added substance fabricating, this procedure can deliver parts from a moderately extensive variety of economically accessible powder materials. These include polymers

  • Nylon
  • Polystyrene; metals including steel, titanium
  • Compound blends; composites
  • Green sand.

Contextual analyses in the car division are different and numerous have their underlying foundations in master ventures. For instance, a plastic laser-sintering machine from EOS has tackled the issue of how to extricate more push from battery powered engines driving the front wheels of a Westfield half breed sports auto.

The task is being supported together by Warwick Innovative Manufacturing Research Center and Potenza Technology, a pro in half breed and electric vehicle frameworks. To amplify both the power and the time that the electric drive is accessible to the front wheels, it is critical to anticipate over the top warming of the 396 lithium particle phosphate cells that supply the pivotal motion engines.

SLA Prototypes

ProtoCAM has specific skill in SLA, an added substance fabricating process that uses a vat of fluid UV-treatable photopolymer (sap) and an UV laser to manufacture parts a layer at any given moment. On each layer, the laser bar follows a section cross-section design on the surface of the fluid tar.

Presentation to the UV laser light cures or sets the example followed on the tar and it holds fast to the layer beneath. The organization says its car clients ask for parts that range from motor parts and body/trim segments, through to instrument boards and focal points.

A noteworthy car producer acknowledged an offer to manufacture them a free example out of NeXT gum to test its warmth diversion and effect quality. They were constructed for a back window wiper arm gathering. The length of the fundamental bit of the arm was 26″, which was longer than RPDG’s vat estimate so the part must be manufactured from two pieces.

The part completed perfectly and was introduced on a genuine working model of the vehicle: the tar did not divert in the wake of sitting in the mid year sun and held up to the enactment of the wiper without twisting. The customer is currently considering utilizing NeXT sap to supplant the customary composite edges beforehand utilized as a part of this sort of testing.

Digital Modeling and Fabrication

by Alexander J.
written by Alexander J.

Digital Modeling and Fabrication is a plan and generation process that joins 3D displaying or figuring helped outline (CAD) with other substance and subtractive assembling. Added substance fabricating is otherwise called 3D printing, while subtractive assembling may likewise be referred to as machining and numerous different advancements can be used to physically deliver the planned for items.

Machine design takes into account various factors like how kinetics and kinematics can impede its control of energy or motion. Basically, you will have to implore a specified process which gives guidelines for machine design.

Before you finally manufacture a machine, you have to align to steps in machine design. Besides the basic steps you have to get on the ground and benchmark, determine the purpose of your machine, setting goals and brainstorming as well as creating a prototype and testing it. Digital machining takes a refined approach with new metrics.

Fabrication

fabrication

Carefully manufactured items are made with an assortment of CAD programming bundles, utilizing both 2D vector drawing, and 3D demonstrating. Kinds of 3D models incorporate four models wireframe, strong, surface and work. A plan is having at least one of these model types.

Machines for fabrication

Three fabrication machines well known for manufacture:

  • CNC Router
  • Laser shaper
  • 3D Printer

  1. CNC Router

CNC stands for Computer Numerical Control. CNC factories or switches incorporate exclusive programming which translates 2D vector illustrations or 3D models and changes over this data to a G-code, which speaks to particular CNC works in alphanumeric configuration which the CNC plant can decipher.

CNC machines usually have a G-code. G-codes are any words in a CNC program which begin with the letter G. This code tells the CNC machine what type of action to perform and it makes them more relative to CNC technology.

cnc router

As a result, CNC machines are able to conduct movement rapidly in between cuts. With automation they can also send controlled feed in an arc. Such fabrication machines are mills, lathes, drilling machines and plasma cutters.

The G-codes drive a machine device, a fueled mechanical gadget ordinarily used to manufacture components. CNC machines are ordered by the quantity of tomahawks that they have, with 3, 4 and 5 hub machines all being normal and modern robots being portrayed with having upwards of 9 axes.

Civilization has scaled its way past human labor. In big companies you are bound to find machine workers outnumbering human labor. The essence of this is to increase work output and it is all held together by Computer Numerical Control (CNC).

cnc router1

CNC systems are automated and this trademark has brought about an alliance with computers that program sequences for processing equipment and machine tools. While CNC was overly a manufacturing venture when it was first discovered, it has slowly found its way into the processing arena.

CNC machines are particularly fruitful in processing materials, for example, plywood, plastics, froth board, and metal at a quick speed. CNC machine beds are typically suitably broad to allow 4′ × 8′ (123 cm x 246 cm) sheets of material, including froth a few inches thick, to be cut.

  1. Laser cutter

The laser cutter is a machine that uses a laser to cut materials, for example, chip board, matter board, felt, wood, and acrylic up to 3/8 inch;1 cm thickness. The laser shaper is frequently packaged with a driver programming which deciphers vector illustrations created by any number of CAD programming stages.

The laser shaper can balance the speed of the laser head, and also the force and determination of the laser shaft, and accordingly is capable in both to slice and to score material, and also estimated raster graphics. Articles cut out of materials can be utilized as a part of the creation of physical models, which will just require the get together of the level parts.

  1. 3D Printers

3D printers utilize an assortment of techniques and innovation to gather physical renditions of computerized objects. Ordinarily work area 3D printers can make little plastic 3D objects. They utilize a move of thin plastic fiber, liquefying the plastic and after that saving it unequivocally to cool and solidify. They typically fabricate 3D objects from base to top in a progression of numerous thin plastic flat layers. This procedure frequently occurs throughout a few hours.

Intertwined Digital Modeling

Intertwined digital displaying, otherwise called combined fiber manufacture, utilizes a 3-pivot automated framework that expels material, ordinarily a thermoplastic, one thin layer at any given moment and logically develops a shape. Cases of machines that utilization this strategy are the Dimension 768 and the Ultimaker.

Stereolithography 

Stereolithography utilizes a high force light projector, more often than not utilizing DLP innovation, with a photosensitive polymer sap. It will extend the profile of a protest fabricate a solitary layer, curing the gum into a strong shape.

At that point the printer will move the question off the well-trodden path by a little sum and task the profile of the following layer. Cases of gadgets that utilization this technique are the Form-One printer and Os-RC Ill iOS.

Specific Laser Sintering

The specific laser sintering utilizes a laser to follow out the state of a question in a bed of finely powdered material that can be combined by utilization of warmth from the laser. After one layer has been followed by a laser, the overnight boardinghouse completed part is moved off the well-trodden path, a thin layer of the powdered material is spread, and the procedure is rehashed.

Specific Laser Sintering

Run of the mill materials utilized are alumide, steel, glass, thermoplastics (particularly nylon), and certain pottery. Case gadgets incorporate the Formica P 110 and the Eos EosINT P730.

Powder Printer

Powder printers work in a comparable way to SLS machines, and ordinarily utilize powders that can be cured, solidified, or generally made strong by the utilization of a fluid cover that is conveyed by means of an inkjet print head.

Ordinary materials obtain mortar of Paris, dirt, powdered sugar, wood-filler holding putty, and flour, which are commonly cured with water, liquor, vinegar, or some blend thereof. The real preferred standpoint of powder and SLS machines is their capacity to ceaselessly bolster all parts of their articles all through the printing procedure with unprinted powder.

This allows the generation of geometries not effortlessly generally made. Nonetheless, these printers are frequently more perplexing and costly. Cases of printers utilizing this strategy are the ZCorp Zprint 400 and 450.

Turning an Electronic Prototype into a Product

by Alexander J.
written by Alexander J.

Electronic prototyping is the creation of a user interface that is similar and acts like it has been completely coded and executed. Electronic prototypes look and feel very responsive, hence are the best candidates for assessment of detailed interfaces, page layout and direction finding.

After agreement on the functionality and overall flow then electronic prototyping is approved. Electronic prototyping is usually the next step in paper prototyping. When the electronic prototype is complete it is given to participants to test if they perform the required task.

Most of the electronic prototyping designers should possess skills such as programming, soldering, circuit designing, and wiring. This is to enable them prototype products that integrate hardware and form the best designs that when applicable they form a quality technology product.

Dan O’Sullivan and Tom Igoe are considered to have laid the way for electronic prototyping by the book they wrote on Physical Computing. In Italy some professors and students came up with Arduino Platform, these were to make electronics much simpler for electronic prototyping designers.

Electronic prototyping is a major contributor to the development and manufacturing a large number of products and services that make up the largest end-user products in the market.

Importance of Electronic Prototyping

Electronic prototyping can show and permit for tests and fine-tune on a number of features of your electronic product such as;

  • Efficient design elements for a better electronic product.
  • The simplicity or difficulty of developing a product with a particular plan.
  • Outer look of the casing.
  • Interior layout of the product, as well as how and where wiring and additional electronic features will be set.

Procedures for Electronic Prototyping

For a better electronic device, a good design should have been made. This is made possible electronic prototyping. The following are the procedures for electronic prototyping;


  • Pre-Design Your Product

In electronic prototyping like other of methods of prototyping, pre-designing is essential. For proper budgeting, I highly recommend you to pre-design your product before implementing the idea into a reality.

Electronic prototyping pre-design

Electronic prototyping pre-design will help you determine the correct number of products you will manufacture so as to reduce the cost of manufacturing. Most developers and entrepreneurs usually skip these procedure landing them into losses, but if they were to pre-design there products it would be cheaper and could have made more profits.

Having a clue on the production cost really helps, hence created a predictable hardware report. The report consists of an initial design for an electronic prototype design of your product. It also has precise estimations on the cost of development, scaling, and manufacturing of the product. Another thing is not building castles on the profits you may get, companies such as Apple, Microsoft or Samsung do not estimate their profits before. Hence you should not have estimates of your electronic prototype profits.

Electronic Prototype Representation and Printed Circuit Board Design

For an ideal electronic prototype, you should come up with a representation and PCB design facilities. This electronic design is also known as a schematic diagram that is related to a house blueprint. It is always advisable that you have a schematic diagram for every part of your system. The representation has every feature, from microchips to meek resistors, and connects.

creating the electronic prototype representation

To create a representation of an electronic prototype you are needed to use a special electronic design software. DipTrace is the highly recommended software in designing of electronic prototypes and it is simple to use. If you are an upcoming designer I strongly advise you to use DipTrace due to its affordability.

Once you are complete creating the electronic prototype representation, you will start designing the definite Printed Circuit Board. Many designers find difficulty in creating a printed circuit board layout is usually tiresome and time-consuming. Hence designing of the printed circuit board is done by the same software used to create the electronic prototype representation. The software ensures that the printed circuit board design adheres to all the design rules and should be similar to the representation.

If your electronic prototype product is small, then the tighter the components must be together and the more time it will consume to come up with the printed circuit board layout. For the wireless or large power consuming products, the layout becomes more critical. Many printed circuit board designs the most crucial part are the power channeling, wireless circuits, and any high-speed signals.

Bill of Material, Printed Circuit Prototypes, Evaluation, and Programming

During the creation of an electronic prototype, there should be the generation of how much cost will the manufacturer incur? Bill of material lists the quantity, component specifications and the part number required.

After designing the printed circuit board design, then your software will allow you to output it in a Gerber format with a single file for each layer. The Gerber files are taken to a prototype shop for small capacity runs or can be taken to vast manufacturers for high volume manufacture. Reaching the manufacturers or the prototyping shops, then all the electronic components are fused onto a board.

When assembling the boards I highly endorse the use of SeedStudio Fusion. They have very affordable prices on quantities from five to eight thousand boards and also offer three-dimensional printing facilities.

Also for printed board designs, I recommend San Francisco Circuits and Sunstone Circuits as alternatives in the electronic prototyping of your printed circuit boards. For a fully assembled boards, it takes between one to two weeks. Advanced printed board circuit methods are there but at high costs.

For many electronic prototypes, evaluation is necessary this is because most do not work perfectly from the start. You have to go through numerous repetitions before finalizing the scheme. In this step, you have to notice, debug and fix arising issues with your electronic prototype. This stage is usually costly and takes a lot of time.

programming the microcontroller unit

The next stage after an evaluation is programming the microcontroller unit. A microcontroller acts as the brain of the electronic product. It is very tiny and is same to a microprocessor. Programming of the microcontroller is so essential for the product to perform its required function. The firmware program is permanently put in storage in the microcontroller memory but it is programmable.

Accreditation

For every electronic product sold they must numerous categories of certifications. Certifications differ contingent on which country the product will be sold. These enables the company to know how many devices are sold to a certain country.
