In the SMT patch processing workshop, during the PCB board processing, measures are taken to protect the PCB board from electrostatic hazards by employing a PCB tray or an anti-static card board. The latter, also known as an anti-static card board, primarily serves to mitigate PCB board damage caused by vibration during transportation, thus reducing the damage rate. The tray’s groove design not only conserves space but also enhances tray fastening, significantly lowering defective product occurrences, thereby enhancing work efficiency and refining the production process.
2. The operator should regularly clean the anti-static container and anti-static turnover box. Additionally, the anti-static table mat, tools, and containers should be cleaned with neutral detergent on a monthly basis.
When selecting an appropriate PCB card board, it is crucial to choose one that ensures the quality of the PCB. The material of the tray must possess the following characteristics:
① High dimensional stability
② Good thermal shock resistance
③ Retains flatness after repeated use
④ Corrosion resistance to flux and cleaning agents
⑤ Non-absorbent to moisture
In the PCB manufacturing and assembly process at the SMT patch processing factory, it’s imperative not only to use anti-static pallets to maintain production quality but also to ensure proper anti-static protection in the production workshop. Operators should wear electrostatic wristbands, electrostatic clothing, and electrostatic shoes to provide effective electrostatic protection for PCB production.
