Introduction For How To Control The Quality Of PCB Board

Quality is the survival of an enterprise, if the quality control is not in place, the enterprise will not go far, if the PCB factory wants to control the quality of the PCB board, then how to control it?

We want to control the quality of PCB board, must have a quality control system, which is often referred to as ISO9001, usually, the concept of a quality control system is real-time quality measurement and supervision, when a thing has a unified measurement standard and supervision standard, 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 is not guaranteed, make PCB great may also have a variety of problems, such as bubbles, delamination, crack, become warped, unequal thickness problem. Therefore, the raw materials must be strictly checked to provide a guarantee for the production behind.

When the quality of raw materials is guaranteed, what needs to be paid attention to is the problems that will occur in the production process. Quality inspection and patrol inspection should be carried out on each process link of 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, a 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 is not up to the standard, full inspection and maintenance will be carried out. We must be responsible for the quality of every piece of PCB board left the factory.
