Quality is the survival of an enterprise, if the quality control is not in place, the enterprise will not go far, PCB factory if you want to control the quality of PCB board, then how to control?
We want to control the quality of PCB board, there must be a quality control system, is often said to be ISO9001, usually the concept of quality control system is real-time quality measurement and supervision, when one thing has a unified measurement standards and supervision standards, want to do a good job is much easier.
Control the quality of the PCB board, first of all have to be strict quality inspection from raw materials, found to have any adverse to timely registration, reporting, and put forward the solution, only to guarantee the quality of its raw materials, is likely to get good quality PCB, if the quality of the raw materials are not guaranteed, make PCB great may also have a variety of problems, such as bubbles, delamination, crack, become warped, unequal thickness problem. So the raw materials must be strictly checked to provide security for the production behind.
When the quality of raw materials is guaranteed, it is necessary to pay attention to the problems that will occur in the production process. Quality inspection and inspection should be carried out on each process link in the production process to ensure that each process has operation instructions, so as to facilitate the comprehensive control of PCB quality.
After the completion of production, sampling inspection must be carried out. Although quality inspection has been carried out in the raw materials and the production process, there are still various reasons for defects. Therefore, sampling inspection should be carried out on the whole batch of PCB boards after the completion of production. Only when the pass rate of sampling inspection reaches the standard will it be allowed to leave the factory. If the pass rate of sampling inspection fails to reach the standard, full inspection and maintenance will be carried out, and the quality of each PCB board shall be responsible for.
