I. Typical PCB prototype

The purpose of PCB prototype is to build and test its functionality, operation, and physical implementation of the design, as well as its structural integrity. Structural integrity refers to the quality and reliability of the PCB, which is usually regulated according to its intended use.

3. Result

As mentioned above, PCB prototyping is usually an iterative process requiring multiple design changes and rebuilding before the final design is completed. In practice, design quality is proportional to the number of iterations, as each iteration produces a better quality design. Although these cycles can be anticipated, it is usually desirable to keep their number to a minimum. The larger the number of iterations, the more time and cost it takes to develop. However, in most cases, time and cost are limited. For example, most developers have a delivery schedule, which may vary depending on the clients.

Parallel prototyping allows the development of a single design or multiple competing designs that meet the design objectives. In fact, because board manufacturing must be stopped until testing and redesign is completed, the typical process can only be as fast as parallel processing. For parallel prototypes, alternative designs can be manufactured during this downtime, which will significantly increase efficiency.
