To do a good job, one must first sharpen one’s tools. This means: A craftsman must ensure their tools are sharp to do their work well.
In our product smart manufacturing, while having advanced equipment, we must also strictly control the processes and inspection standards. Only in this way can we produce high-quality products, which are the foundation of a brand in the market. Today, we will share Huawei’s PCBA inspection standards for your reference and learning.
This standard describes the materials, methods, and qualification requirements for producing high-quality solder joints and PCBA.
Regardless of the other feasible methods used, it must be able to produce complete solder joints that meet the qualification requirements described in this standard.
This standard is applicable for quality inspection personnel and process personnel at trial production and production sites when conducting PCBA appearance inspections.
