Prototype PCB Necessity and Benefits(1)----Wonderful PCB (hk) Limited

PCB prototype plays a very important role in the creation and design of PCB (Printed Circuit Boards). The design of the Rigid-flex pcb does not depend on single elements rather depends on variety of elements which needs expertise and testing for several times. And prototype gives you the opportunity to check your product before production. Actually, we can say that the design depends on indistinct set of necessities. This is produced to define the required functions for the electrical and mechanical products. And the prototype helps to fulfill these needs by giving you a chance for proving your design.
The designers include all the required functionalities those can fit in the board. As regarding to the requirements, the board changes its shape. Sometimes it's large with the extensive requirements. And sometimes it's small with fewer requirements. Again many things are needed to make a PCB prototype of production stage. Among them, functionality with reliability is a must. The complexity and functionality determines the required number of layers. Some board consists of only two layers as they have less functionality and some have even more than 32 layers for their complexity and high functionality. And the size also differs a lot. As the board has to sit perfectly into its desired system, it must be made in the perfect shape. The tolerance is also a factor as the layers and copper traces certainly depend on it. Most PCB has a design with a tolerance that makes the layers and copper traces even more critical. As they are designed with highly tight tolerances, they are made highly integrated. And this integrity sometime causes some critical problems. So, it must be checked carefully for the accuracy. The voltage must be moderate with the application and the signals must also be clean. Again, the surface components must meet the required tolerance. And after considering all these respects, the developed first board is called the prototype. These are developed for testing. They are mainly made depending on the number of testing required. After the testing is completed, the production begins with the design.
