There are many operating rules for PCBA processing, such as not having unrelated debris on the workbench, keeping the workbench clean, not holding PCBA patches with hands, strictly following the process operation, etc. During processing, it is also important to understand commonly used labels and regularly maintain the equipment. Therefore, the following will provide a detailed introduction to the relevant content.

1、 Operation rules for PCBA processing

1. There should be no food or beverage in the PCBA work area, smoking should be prohibited, unrelated items should not be placed, and the workbench should be kept clean and tidy.

2. The surface to be soldered during PCBA processing should not be taken with bare hands or fingers, as the oil secreted by human hands can reduce solderability and result in soldering defects.

3. Minimize the operation process of PCBA and components to prevent potential risks. In assembly areas where gloves are necessary, dirty gloves can cause contamination, so gloves need to be replaced frequently when necessary.

4. Do not apply oils or detergents containing silicone resin to maintain the skin, as they can cause issues with weldability and adhesive properties of conformal coatings. There are specialized detergents available for PCBA soldering surfaces.

5. It is necessary to label EOS/ESD sensitive components and PCBA with appropriate EOS/ESD markings to avoid mixing with other components. In addition, to prevent ESD and EOS from endangering sensitive components, all operations, assembly, and testing must be completed on a workbench that can control static electricity.

6. Regularly inspect the EOS/ESD workstations and confirm that they can operate normally (anti-static). The various risks of EOS/ESD components can be caused by incorrect grounding methods or oxides in the grounding connection, so special maintenance should be given to the joint of the "third wire" grounding terminal.

7. To prevent physical damage caused by stacking PCBA, specialized brackets should be equipped on the assembly work surface and placed according to their types.

In PCBA processing, strict adherence to these operating rules and correct operation are necessary to ensure the final quality of product use, reduce component damage, and lower costs.

2、 Precautions for PCBA processing

1. Before operating the SMT machine, it is necessary to understand the commonly used labels of the SMT machine.

2. Before starting the surface mount machine, the operator should conduct a comprehensive inspection of the machine.

3. The start-up sequence of the surface mount machine must be strictly followed. The surface mount machine must have detailed operating instructions.

4. Timely and regularly troubleshoot and maintain the surface mount machine.
