Static control methods: Static control should take different measures according to different situations and different positions.
① Anti-static process for fixed positions
Anti-static leakage process should be adopted for fixed positions. One static control position becomes an anti-static point, and one production line constitutes a safe operation area. A safe operation area includes: a. Grounding busbar; b. Anti-static floor mat; c. Anti-static table mat; d. Anti-static wrist strap; e. Anti-static tools (such as electric soldering iron, etc.). The above five must be well grounded to be effective.
② Anti-static process for mobile positions
Mobile positions are divided into three types: fully mobile, semi-mobile and fixed when mobile. Mobile positions can use static leakage method and composite neutralization method to cross-use, and process control method can be supplemented with complete process plan (such as anti-static packaging and transfer vehicle for items when picking materials, etc.).
③ Process requirements for fixed single equipment:
a. The equipment should be well grounded;
b. Anti-static floor mats should be laid around necessary equipment;
c. Operators should wear anti-static clothes, ESD hats, ESD wrist straps, esd heel grounder etc.
