The prototype PCB is a template or standard of what will look and function as a final PCB. The reproduction of a PCB prototype is a procedure that go before manufacture and the next launching of new PCBs. This process confirms whether the proposed PCB design will work as expected, revealing any drawbacks and thus allowing designers to make the necessary changes. All other improvements or alternatives that the designers could imagine were also introduced at this stage. The mass production of any new product can not be initiated simply without a prototype design stage.
Making a prototype does not necessarily reveal any disadvantages if the design is done to perfection. The prototype PCBs in this case will be used to confirm and re-establish that PCB performance is consistent. The manufacturer or buyer can give their opinion on the PCB along with any other suggestions / improvements they may have. PCB designers should always be prepared for all possible outcomes and therefore any processing at this stage should not be considered as an additional cost. Avoiding prototypes and participating in mass production of PCBs can be disastrous in terms of wasted time, effort and money.
Next, generalized phases are presented in the design of PCB prototypes. The first is called proof or proof of principle. This verifies that the logic behind the PCB is achievable. Next, we observed aspects of the size (desirable dimensions) of the expected PCB. After this phase, a visual model is generated and, if approved, starts the final phase, which is the function and the appearance. Whatever it is at the moment, it’s the closest thing to how the real PCB will look. Normally, in the development of PCB prototypes, simulation of circuit current and circuit status are two of the most important processes. Although the simulated system does not work, it is necessary to apply the actual components and materials to the final model or prototype.
The production of prototypes is a time-limited process, it takes at least the time to put the way to actual production. Companies that offer PCB prototype service will also be involved in the production. As such, these companies try to develop good / perfect prototypes. With the advancement of technology and even more, computerization has accelerated the processes of producing prototypes and PCBs and made them error-free. Therefore, it is advisable to choose a PCB company that has the latest technology, which will ensure that the error limit is almost zero, to avoid the use of harmful chemicals and that the size of the PCB is kept as low as possible.
