Quality is the foundation of an enterprise, and it is also the hard cornerstone of development. The first step to ensure quality is to select high-quality plates. If PCB manufacturers want to control the quality of PCB boards, how to control them?
If we want to control the quality of PCB boards, we must have a quality control system, which is commonly referred to as ISO9001. In general, the concept of a quality control system is real-time quality measurement and monitoring. When there is a unified measurement standard and supervision standard, the product quality can be better.
To control the quality of the PCB boards, we must first carry out strict quality inspection from the raw materials, and any defects must be registered and reported in time, and solutions should be proposed. Only by ensuring the quality of raw materials, it is possible to obtain high-quality PCB boards. If the quality of the raw materials is not guaranteed, the produced PCB boards are also likely to have various problems, such as blistering, Layered, cracking, board warpage, and uneven thickness and so on. 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 the problems in the production process. Strict quality inspection is required for each process in the production process to ensure that each process has operating procedures to facilitate comprehensive control of PCB quality.
After the production is completed, a sampling inspection must be carried out. Although quality inspections are carried out in both the raw materials and the production process, there are still defects due to various reasons. Therefore, after the production of PCB boards is completed, it is necessary to conduct sampling inspection of the entire batch of PCB boards. As long as the pass rate of random inspection meets the standard, it is allowed to leave the factory. If the pass rate of random inspection does not meet the standard, all PCB boards should be inspected. We must be responsible for the quality of every PCB that leaves our factory.
We are specialized in PCB and PCB assembly production, also we have great confidence in the quality of our products.
