How To Make Your Electronic Prototype Product Design || Get Your PCB Electronics Designed

out of the box, product design

Compu Drive System is among the best prototype companies in the globe to carry out as professional prototype designers and we know the cheapest way to make a prototype design and fabricate prototypes in INDIA along with complete PCB Electronics design works.

The entire engineering from design thinking process to, making of working prototype model is all done under one roof of Compu Drive System, Kolkata, India Office.

After the design thinking process is over, our electronic prototype product design work starts with electronic circuit design, printed circuit board (PCB Electronics) layout, PCB fabrication, sourcing and procurement of electronic components, PCB Assembly (PCBA), working and testing of PCBA.

Then starts the hardware design process, where machine design and fabrication or 3D model design starts, along with 3D print of enclosure design, all depends as per customized prototype to be build.

Next step of prototype process is to make the device function in intelligent way, so here starts the longest process of microcontroller coding and feeding process instructions. This is the point where designed PCBA interfaces with the sensors and hardware designed and starts dancing depending upon the coded instructions. This is the most complicated and restless phase of innovative design process but very enjoyable and interesting phase of a designers life.

Today’s designed prototypes in 2020 are generally smart products by nature, which further gets associated with Internet of Things also called IoT. Thus a new phase in design starts is coding the mobile, PC or cloud based applications as per customers need.

After all prototype development process are complete, then starts the vigorous testing of PCBA, sensors, hardware, fine tuning of microcontroller instructions, fine tuning of instructions, look, style and  color of app designed.

Generally a prototype product are not very attractive look wise, for the parameters like product look, color, shape, size, and weight are thought in the next phase of prototype to manufacturing process.

Once the entire process of prototype development is over, then starts professional photography product video shoot to make a client’s business demo video trailer for video presentation and advertisement of the prototype product.

So the last and important part is the training and hand over of prototype product to the respective client and now wait for the user feedbacks and further make the final improvements.

So how did you like the short write up, for a very lengthy prototype design process? The process sometimes takes 3 months to even 2 years; depending on the client’s project type.

If you find this little write up informative and useful, I hope you will share it with your business friends and clients.  I will also like to hear your comments related to this subject.

Beginners Guide To Start Electronics Project

Compu Drive System, Breadboard

Hello, my dear young and electronic project enthusiastic friends, I know you love to build and play with electronic circuits. In this post I have mentioned some dos and don’ts, to grow your practical knowledge in electronic circuits.

Never start building your first few electronics projects with a big circuit having 10 to 20 plus electronic components or a theme project something like A robotic car or gesture controlled robot or an assignment project been given by your college. Always start building your first few circuits which small 4 to 8 components and get a grip to breadboard connection, making jumper wire, understanding and wiring a small circuit to the breadboard, testing, getting the output etc. You can visit my blog category building small circuit for your small circuit reference. 

Never start your first project on a veroboard with soldering concepts rather I prefer breadboard even after 30 years being associated in electronics circuit design and prototype product design concepts.

Purchase some basic tools like wire cutter, tweezers, nose pliers, a small magnifying glass, hot glue gun and glue stick, sharp small knife, small screwdriver set, digital multimeter and very important is a bench power supply with at least 0 to 30 Volts and current 0 to 5AH both adjustable, later on a soldering iron, de-soldering pump, solder wire, solder flux can be added to the tools kit. Your tools and how you use and maintain them proves your love and regards to your subject.

Purchase some basic components like resistors, capacitors, diode and LED’s, transistor NPN and PNP types, some simple sensors like LDR, infra photodiode, infra LED, NTC and PTC type of temperature-dependent resistors, condenser microphone, switch SPST, SPDT, DPST and DPDT, some output device like speaker, buzzer, small PMDC motor. You can visit my post component list for new comers to build small circuits.

Once you love building small practical circuits along with your engineering studies, make it a habit at least building one circuit a week that is around 50 plus circuits you will build up in a year. If you can use even 3 years of your engineering in my direction I challenge world will be proud to recruit electronics engineers having full theoretical and hands on practical expertise’s and exposure.

If you find my posts are good and helpful for you the young growing electronics engineers please do share and comments your views, because your interaction in form of comments makes me grow to write more good posts. I will continue giving more write-ups. Love You All.
