Thin line conformal coating apparatus and method

摘要: PROBLEM TO BE SOLVED: To provide an applicator that adds conformal coating to electrical composition.SOLUTION: A system employs comprising a cylinder with needle valve attached. control device comprises timer supplies series of electric pulses solenoid. By using each pulse, the solenoid applies pressurized air piston, thereby opening valve, and this allows material pass through valve. The is closed over retention time between pulses, released from dispensation in response closure
