Quality is the foundation of an enterprise and the hard cornerstone of development. The first pass to ensure quality through strict inspection is to select high-quality plates. If PCB manufacturers want to control the quality of PCBs, how to control it?
If we want to control the quality of PCBs, we must have a quality control system, which is commonly known as ISO9001. Generally, the concept of quality control system is real-time quality measurement and supervision. When a thing has a unified measurement standard and supervision standard, it is easier to do it well.
To control the quality of PCBs, we must first carry out strict quality inspections from raw materials. Any defects must be registered and reported in time, and solutions should be proposed. Only by ensuring the quality of raw materials can we obtain high-quality PCBs. If the quality of raw materials is not guaranteed, the PCB produced may also have various problems, such as blistering, delamination, cracking, plate warpage and uneven thickness. Therefore, raw materials must be strictly controlled to provide guarantee for subsequent production.
While ensuring the quality of raw materials, we should also pay attention to possible problems in the production process. Quality inspection shall be carried out for each process in the production to ensure that each process has operating procedures, so as to facilitate the overall control of PCB quality.
Sampling inspection must be carried out after production. Although quality inspection has been carried out in raw materials and production process, there are still defects caused by various reasons. Therefore, after the production of PCB boards is completed, the whole batch of PCBs need to be sampled for inspection. As long as the sampling inspection pass rate reaches the standard, it is allowed to leave the factory. If the sampling inspection pass rate fails to meet the standard, full inspection and maintenance shall be carried out, and the quality of each PCB delivered must be responsible.
