PCB Tech - Process requirements for PCB processing

Process requirements for PCB processing
PCB processing has different methods, and the raw materials for PCB processing are tens of thousands, and there are different processing procedures corresponding to them, and there will be differences in order when the same material is processed by the same method. So for professional PCB processing manufacturers, what are the technological requirements for PCB processing with many processing methods?

Process requirements for PCB processing

1. Number

After PCB processing is completed, it should be numbered immediately. In order to prevent the marks from being lost during processing and cleaning, a uniform number should be clearly written on both sides of the board with a marker pen. For future management convenience, this number should be kept forever.

Second, the correct placement

In order to make the bumps and scratches on the surface of the components as little as possible, during the process of processing, transporting, and storing the PCB, care must be taken to prevent bumps, and the boards need to be separated and stacked to avoid Contact each other, so that the PCB boards are damaged each other.

Third, the finishing process of PCB processing

After the PCB is processed and tested, it is necessary to finish the whole board, including removing the extraneous items on the surface such as excessively high pins and metal residues; beautify the finished PCB after processing, if possible Conceal the front flying line; for the back flying line, it is better to take shortcuts; while the solder joints and longer flying lines should be covered and fixed with the least glass glue, so that they will not be affected The exterior is beautiful. Because for first-class PCB processing manufacturers, both internally and externally are equally important; therefore, redundant logos must be removed, the color must be consistent, and the PCB must be kept clean. If dirt is stained, use a brush or Clean with cotton balls.

After each piece of PCB is processed, it has to go through tedious finishing work before it can be packaged, and the finished product obtained by each consumer has gone through countless processes and there can be no mistakes. Every honest and reliable PCB processing manufacturer strictly implements the above process, and is constantly striving for perfection, only to be more professional for itself, and only to bring more affordable PCB processing products to consumers who trust it. At present, the country has higher and higher requirements for environmental protection and greater efforts in link governance. This is a challenge but also an opportunity for PCB factories. If the PCB factory is determined to solve the problem of environmental pollution, then FPC flexible circuit board products can be at the forefront of the market, and the PCB factory can get the opportunity to develop again.
The Internet era has broken the traditional marketing model, and a large number of resources have been gathered together to the greatest extent through the Internet, which has also accelerated the development speed of FPC flexible circuit boards, and then as the development speed accelerates, environmental problems will continue to appear in PCB factories. In front of him. However, with the development of the Internet, environmental protection and environmental informatization have also been developed by leaps and bounds. Environmental information data centers and green electronic procurement are gradually being applied to the actual production and operation fields.
