Abstract
An apparatus for preventing electrostatic destruction of integrated circuits coats an electrostatic agent on surfaces of the integrated circuits to avoid accumulation of static electricity caused by dynamic contact friction. The apparatus comprises a belt, at least one motor, at least one spray nozzle, at least one dispenser or controller and at least one photo switch. The integrated circuits are placed on the belt. The motor drives the belt and therefore the integrated circuits step by step to the spray nozzle to coat the electrostatic agent on the surfaces of the integrated circuits. The controller controls the output rate of the electrostatic agent from the spray nozzle. The photo switch is connected to the spray nozzle and dispenser to detect the integrated circuits as they pass the spray nozzle.
