Electronic components, especially ICs and microprocessors, are highly sensitive to static electricity. During \u30b3\u30f3\u30d5\u30a9\u30fc\u30de\u30eb\u30fb\u30b3\u30fc\u30c6\u30a3\u30f3\u30b0<\/strong><\/a>, activities such as spraying, airflow movement, and handling can generate static charges. Without proper protection, even a small discharge can:<\/p>\n\n

All equipment, workstations, and operators must be properly grounded. This ensures that static charges are safely dissipated instead of accumulating during PCB\u30a2\u30bb\u30f3\u30d6\u30ea<\/strong><\/a>.<\/p>\n
Use anti-static mats, flooring, and work surfaces designed to prevent charge buildup. These are standard in professional SMT\u30a2\u30bb\u30f3\u30d6\u30ea<\/strong> \u74b0\u5883\u3060\u3002.<\/p>\n
Ionizers neutralize static charges in the air, especially in spray coating processes where airflow can generate static. This is particularly important for \u30b3\u30f3\u30d5\u30a9\u30fc\u30de\u30eb\u30fb\u30b3\u30fc\u30c6\u30a3\u30f3\u30b0<\/strong> lines.<\/p>\n
Operators should wear ESD wrist straps, gloves, and anti-static clothing to minimize charge transfer during handling in \u30d7\u30ed\u30c8\u30bf\u30a4\u30d7PCB\u30a2\u30bb\u30f3\u30d6\u30ea<\/strong><\/a>.<\/p>\n
Maintaining relative humidity (typically 40\u201360%) reduces static buildup. Extremely dry conditions increase the risk of ESD events in PCB\u30a2\u30bb\u30f3\u30d6\u30ea<\/strong> areas.<\/p>\n
Containers, masking materials, and tools should be made of anti-static or dissipative materials to prevent charge accumulation.<\/p>\n
Coating machines and spray systems should be designed with ESD protection in mind, including proper grounding and regular maintenance.<\/p>\n
