How does the PCB factory control the quality of the PCB board

Quality is the foundation of a company's survival. If quality control is not in place, the company will not go far. If PCB factories want to control the quality of PCB boards, how should they control it?

If we want to control the quality of PCB boards, we must have a quality control system, which is commonly 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 When it is standard, it is much easier to do well.

To control the quality of PCB boards, we must first conduct strict quality inspections from the raw materials. If any defects are found, we must promptly register, report, and propose solutions. Only when the quality of the raw materials is guaranteed can we get high-quality products. PCB boards, if the quality of the raw materials are not guaranteed, the PCB boards made may also have various problems, such as blistering, delamination, cracking, board warping, uneven thickness and other issues. Therefore, raw materials must be strictly inspected to provide guarantee for subsequent production.

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 inspection should be carried out on each process link of the production process to ensure that each process has operating instructions to facilitate the PCB The quality is fully controlled.

After the production is completed, random inspections must be carried out. Although the quality inspections are carried out in the raw materials and the production process, there are still defects caused by various reasons, so the whole batch of PCB boards will be randomly inspected after the production is completed. As long as the qualified rate of the random inspection is up to the standard, the factory is allowed to leave the factory. If the qualified rate of the random inspection is not up to the standard, full inspection and maintenance will be carried out. You must be responsible for the quality of each PCB board that is shipped.
