PCBA processing seven-point operating rules

PCBA is the production process of PCB empty board first through SMT parts, and then through DIP plug-in, which involves a lot of fine and complex process flow and some sensitive components. If the operation is not standardized, it will cause process defects or component damage, affecting product quality and increasing processing costs. Therefore, in PCBA processing, it is necessary to comply with the relevant operating rules and operate in strict accordance with the requirements.

Operating rules for PCBA processing

1, in the PCBA work area should not have any food, drink, no smoking, do not place non-work related debris, keep the workbench clean and tidy.

2, the surface of the PCBA patch to be welded must not be taken with bare hands or fingers, because the grease secreted by the human hand will reduce the weldability and prone to welding defects.

3. The operating steps of PCBA and components are reduced to a minimum to prevent dangers. In assembly areas where gloves must be used, soiled gloves can cause contamination, so replace them frequently if necessary.

4, do not use skin protection grease or various detergents containing silicone, which can cause problems in the solderability and bonding properties of the coating. Specially formulated detergents for PCBA welding surfaces are available.

5, EOS/ESD sensitive components and PCBA, must be marked with appropriate EOS/ESD logo to avoid confusion with other components. In addition, in order to prevent ESD and EOS from endangering sensitive components, all operation, installation and testing must be completed on the workbench that can control static electricity.

6. Check the EOS/ESD workbench regularly to confirm that they can work normally (anti-static). Various hazards of EOS/ESD components can be caused by incorrect grounding methods or oxides in the ground connection, so special protection should be given to the "third wire" ground terminal connector.

7. It is forbidden to stack PCBA, which will cause physical damage. Special brackets should be configured on the assembly working surface and placed according to type.

In the manufacturing of PCBA patch processing, these operating rules should be strictly observed, and the correct operation can ensure the final use quality of the product and reduce the damage of components. It can provide one-stop services from upstream electronic component procurement to PCB production and processing, SMT patches, DIP plug-ins, PCBA testing, finished product assembly, etc.
