Basic Knowledge of PCB Prototype

Posted on 2020-07-08

The PCB prototype is a model or sample of the final PCB appearance and function. PCB prototype or low-cost PCB prototype is a small device used to connect electronic components to ensure the smooth operation of the product. This process determines whether the proposed PCB design will perform as expected, thereby revealing any possible defects and thus enabling the designer to make any necessary changes. At this stage, any other improvements or alternatives that the designer may think of are also introduced. The mass production of any new product is inseparable from the PCB prototyping service and cannot simply be started without the prototype design stage.

PCB prototype

PCB prototype design does not necessarily find any defects, because sometimes the design is perfect. After the PCB prototype board is completed, the electronic components of the product will be connected into a PCA (printed circuit assembly), which is usually completed with the help of soldering. The manufacturer or customer can then provide their opinions on the PCB and other suggestions/improvements they may have. PCB prototype service designers should always be prepared for any possible outcome, so any rework at this stage should not be considered as an additional cost. Bypassing prototype design and participating in the mass production of PCB prototype boards will only make it fail, and it will definitely be catastrophic in terms of wasting energy, time and money.

The following is the generalized stage of PCB prototyping

The first is called breadboard testing or proof of principle. This will check if the logic behind the PCB prototype board is achievable. The next step is to check the dimensions (preferred dimensions) of the expected PCB prototype board. After this stage, a visual model is generated, and if approved, the final stage of function and appearance is started. The achievement achieved at this moment is the closest to the actual PCB prototype board. Generally, in the prototype design of PCB, the simulation of the current in the circuit board and the state of the circuit are the two most important processes. The actual components and materials for the final model or prototype can only be implemented before the simulation system works as required.


Advances in technology and computerization have paved the way for public convenience to produce PCBs/s worldwide. Prototyping is a modern system used to cost-effectively manufacture PCB boards, mainly the main electronic components.

Actively bring in PCB prototype manufacturers. Prototypes are not ordinary products. Like photocopiers, users can easily use them. PCB prototype boards need to be researched before use. As a modern, reasonably priced project and investment, it takes a lot of experience to judge the equipment before acquiring it.

PCB milling system

If the company is involved in mass production, the first process is to make a master copy before it is checked, it can be continued to the next step of producing millions. Adopting PCB milling system, as it ensures the speed of creation and testing, it reduces the tedious traditional process.

Compared with chemical etching –no chemicals. PCB milling is done cleanly by subtractive methods without involving the use of chemicals. Cut the circuit board to remove the copper part. The speed of completing the task is precisely controlled by the user.

Compact –Imagine a machine that handles multiple complex tasks of milling, drilling, milling, and other special processes, where the tasks are all completed by the prototype machine. The only additional item required to operate the equipment is the use of industrial vacuum cleaners for backup for maintenance. Compactness can be achieved during the setup process, which is also part of the training required to handle prototypes.

Mechanism –PCB prototype manufacturing is a precision-controlled device with a high degree of mechanical manufacturability. It involves a drive system that is fully manipulated by design components. Once proposed, everything depends on the integration of the user and the software, coordinating the movement of the head in its coordinates (x, y and z). It is computerized so that the repeating process is error-free.

Safety –High complexity designed to use small bits. For wiring, it has been customized according to the rigidity of the application. However, for safety reasons, users need to wear protective glasses for the eyes. The tiny dust emitted must be vacuumed all the time.


In conclusion

Prototype production is a time-limited process and should spend the least amount of time for the actual prototype manufacturer. Companies that provide PCB prototype services may also participate in PCB prototype manufacturers. Therefore, these companies strive to develop high-quality/perfect prototypes. Advances in technology and more computerization have accelerated the process of prototyping and manufacturing PCBs, and made them as error-free as possible. Therefore, it is wise to choose prototype manufacturers with the latest technology. This function will ensure that the error range is almost zero, avoid the use of harmful chemicals, and the PCB size is as small as possible, but they are also required by modern electronic equipment.
