The process of PCB board processing requires different methods of PCB processing, and the raw materials of PCB processing are also thousands of, and there are different processing processes corresponding to it. The same material processed in the same way will also have a difference in order. So for professional PCB processing manufacturers, in the face of numerous processing methods of PCB processing, what are the technological requirements?

PCB processing technology requirements

1, the number

Unified numbering should be carried out immediately after PCB processing is completed. In order to prevent mark loss in the process of processing and cleaning, use a marker pen to clearly write the uniform number on both sides of the board. For the convenience of future management, this number should be retained permanently.

2, correct placement

In order to minimize the scratches on the surface of components, in the process of processing, transportation, and storage of PCB, it is necessary to handle with care to prevent collisions and separate the boards from each other to avoid mutual contact and damage to PCB boards.

3. Finishing process of PCB processing

After PCB processing and testing, it is also necessary to conduct post-finishing work on the whole board, including removing excess items on the surface such as high pins and metal residues; Beautify the finished products after PCB processing, such as hiding the positive flying lines as much as possible; For the back of the fly line is less, it is best to take shortcuts all; The solder joints and longer flying lines should be covered and fixed with the least glass glue so that it does not affect the external appearance. Because for the first-class PCB processing manufacturers, both internal and external are equally important; So also remove excess signs, keep the color consistent and keep the PCB clean, such as dirt, clean with a brush or cotton ball.

After each PCB is processed, it can only be packaged after tedious finishing work, and the finished products received by each consumer have gone through countless processes and there can be no mistakes. Every honest and reliable PCB processing factory strictly implements the above process and is constantly striving for perfection, in order to be more professional and bring more affordable PCB processing products to consumers who trust it.

PCB processing requirements _PRECAUTIONS for PCB processing

Notes for PCB processing

PCB design is an important part of PCB engineer’s work. For designers, it will be a great sense of achievement to process their own design drawing and use it successfully. PCB design is more complicated than that of other products. If a small detail goes wrong, the whole PCB board will be scrapped directly. Once the design is finished, the PCB processing link is particularly important. How to accurately process the PCB design drawing? What should be paid attention to in PCB processing?

1. Factory scale

Daily production capacity of PCB factory and experience of cooperating with big brands.

2. Whether the equipment is advanced

PCB factory has stable production equipment, stable production equipment is directly related to the quality of PCB board.

3, whether the process meets the design requirements

It can meet its own process requirements, such as gold sinking process, lead spraying tin, etc., to ensure the quality of the PCB board.

4. Whether the service is in place

In addition to product quality, service quality is also an important factor in the inspection of PCB factories. PCB factories with perfect after-sales systems and strong after-sales guarantees should be selected as far as possible.

After determining the PCB factory for cooperation, submit relevant PCB processing documents to the factory as soon as possible.

For PCB factories, after receiving PCB processing orders, the first and most important step is to carefully check PCB processing documents to avoid a series of subsequent processing problems caused by initial data problems. After the confirmation, the overall process approval, process configuration with their own factories. In the process of PCB, PCB factories should not only ensure the quality of PCB boards but also pay attention to the delivery date. At present, customers have higher and higher requirements on the delivery date, and some users demand 24-hour delivery, which poses a great test to the production capacity of PCB factories and the integration ability of resources of all parties.
