Prototype PCB Necessity and Benefits(2)----Wonderful PCB (hk) Limited

These printed circuit boards prototypes are checked in all critical conditions as everything must be checked and every problem must be solved before the production. Again, the leads and traces are re-measured so that it meets the required thickness. The VIAS and holes need individual programming for each board and their making process is also sophisticated. The tolerances and electrical signals are tested even after the addition of the surface components.
When all the components are added and it is made as the specification, it is finally tested for several times for the required result. The board must also be able to provide proper reliability and effectiveness. In this time, the board is tested without planting it in the environment it is made for. And all steps are recorded. 
And when it meets the standard quality, it is sent for production. But if any wrong occurs, it is tested again and sent for further solution. Even sometimes the whole design is changed for the failure in tests.
The prototype is made by the companies to check their products and inventions before manufacturing. And thus it helps a great deal in the development of PCB.
