How PCB factory controls the quality of PCB board
08 Jan, 2022
Quality is the foundation of an enterprise's survival. 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, how to control it?
If we want to control the quality of PCB boards, we must have a quality control system, which is often referred to as ISO9001. Usually, the concept of quality control system is real-time quality measurement and supervision. When there is a unified measurement standard and supervision for one thing It's a lot easier to do well when it's standard.
To control the quality of PCB boards, we must first carry out strict quality inspections from the raw materials. If any defects are found, they must be registered in time, reported, and proposed solutions. Only when the quality of raw materials is guaranteed, it is possible to obtain high-quality products. PCB board, if the quality of raw materials is not guaranteed, the PCB board made may also have various problems, such as blistering, delamination, cracking, board warping, uneven thickness and so on. Therefore, raw materials must be strictly inspected to provide guarantee for subsequent production.
When the quality of raw materials is guaranteed, it is necessary to pay attention to the problems that may occur in the production process. Quality inspection and inspection should be carried out for each process link of the production process to ensure that each process has a work instruction, so as to facilitate the PCB inspection. Comprehensive quality control.
After the production is completed, a random inspection must be carried out. Although the quality inspection has been carried out on the raw materials and the production process, there will still be defects caused by various reasons. Therefore, the entire batch of PCB boards will be sampled after the production is completed. As long as the qualified rate of the random inspection is up to the standard, the factory will be allowed to leave the factory. If the qualified rate of the random inspection is not up to the standard, a full inspection and maintenance will be carried out, and the quality of each PCB board must be responsible for the factory.
