Essential Anti-Static Requirements in PCB Processing

PCB processing is a crucial technology in electronic manufacturing, involving sensitive components that require strict static electricity protection measures. Here are the key anti-static requirements:

Workshop Anti-Static Requirements

• Equip the workshop with proper anti-static facilities and ensure reliable grounding.
• Maintain a constant temperature and humidity.
• Designate static-safe working areas and display warning signs.
• Regularly inspect grounding systems inside and outside the workshop.
• Control temperature at (25±2)°C and humidity at 65%±5% RH.

Employee Electrostatic Protection Requirements

• Wear designated anti-static overalls and shoes in the anti-static area.
• Use grounding wrist straps or foot straps before handling sensitive components.
• Avoid items that generate static electricity in the anti-static area.
• Store components in anti-static packaging and follow proper handling procedures.
• Use grounding devices on trolleys and shelves.

Operational Considerations

• Discharge static electricity by touching the work surface before handling components.
• Position devices pin-down on the table for static dissipation.
• Grasp integrated circuits by the body to avoid contact with pins.
• Handle electronic components by the edges of the PCB.
• Avoid dragging or sliding components on surfaces.
• Keep non-conductive materials away from static-safe work areas.
• Remove components from anti-static packaging only in safe work areas.
