PCBA patch processing is the process of passing through SMT on the empty PCB board, and then through the DIP plug-in process. Many delicate and complex process flows and some sensitive components are involved. If the operation is not standardized, it will cause component damage or process defects, affect product quality and increase processing costs. Therefore, in the PCBA patch processing, it is necessary to comply with the relevant operating regulations, and the workers must operate in strict accordance with the regulations.
1. The workbench should be kept clean and tidy in the PCBA work area. No food or drink should be stored, personal items not related to work are strictly prohibited, and smoking is strictly prohibited.
2. PCBA patch processing should not be used with bare hands to pick up the soldered surface, because the grease in the fingers will reduce the solderability of the circuit board and increase the probability of soldering defects.
3. The operation steps of PCBA processing and components should be as simple as possible to prevent errors caused by complicated steps. The assembly steps of gloves must be used. Since dirty gloves will cause pollution, new gloves must be replaced frequently when necessary.
4. Do not use skin-protecting oils to coat hands or various silicone-containing detergents, as they can cause problems in solderability. A professionally formulated detergent for PCBA soldering surface is available.
5. For static-sensitive components, they must be marked with appropriate anti-static signs to avoid confusion with other components. In addition, in order to prevent static electricity from endangering sensitive components, all operations, assembly and testing must be completed on a workbench that can prevent static electricity.
6. Check the anti-static workbench regularly to confirm that they can work normally (anti-static). Various hazards of electronic components can be caused by incorrect grounding methods or oxides in the ground connection parts. Therefore, special protection should be given to the joints of the "third line" grounding terminal.
7. It is forbidden to stack PCBA circuit boards, which will cause physical damage. Special brackets should be provided at the work site, and the PCBA circuit boards should be placed completely according to the type.
This is the end of the operating rules for PCBA patch processing. In PCBA patch processing, these operating rules should be strictly followed and the correct operation can ensure the final use quality of the product, reduce component damage and reduce costs.
