A POTTING APPARATUS OF POTTING SYSTEM AND AIR PRESSURE CONTROL METHOD OF DISPENSER OF POTTING APPARATUS IN ABOVE A POTTING SYSTEM

摘要

A potting apparatus of a potting system comprising a loader, a porter, a precure and an unloader, the potting apparatus comprising: a dispenser containing a sealant therein and applying the sealant to a semiconductor chip on a semiconductor film through a dispenser needle; An air supply unit for supplying air into the dispenser for positive pressure in the dispenser; An air suction unit for sucking air in the dispenser to make the pressure in the dispenser negative pressure; And controlling the air supply to make the pressure in the dispenser positive pressure to discharge the sealing agent through the dispenser needle, and controlling the air intake to make the pressure in the dispenser negative pressure so that the sealing agent is not discharged through the dispenser needle by its own weight. It characterized in that it comprises a control unit.;In addition, the present invention is characterized in that it further comprises an air discharge for maintaining the pressure state in the dispenser to the atmospheric pressure state.;In addition, according to the present invention, a control signal is applied according to the control logic of the controller, and the output terminal is turned on / off according to the supply / non- supply of power so that the dispenser is one of the air supply unit, the air intake unit, and the air exhaust unit. And first and second solenoid valves configured to be connected to each other.;On the other hand, the present invention is separated from the protective tape, the loader for sending out the semiconductor film, the porter for coating the semiconductor element on the sent out semiconductor film, the precure to heat and harden the semiconductor film with the element and the curing In the potting system consisting of an unloader for rewinding the semiconductor film, the method of adjusting the air pressure in the dispenser of the porter, wherein the pressure in the dispenser is changed to a positive pressure using an air supply means to apply a sealing agent between the semiconductor film and the semiconductor chip. Doing; When the application of the sealant is completed, the pressure in the dispenser is temporarily maintained at atmospheric pressure; And changing the pressure in the dispenser to a negative pressure state using the air suction means to prevent the coating agent from falling through the dispenser needle by its own weight.;Accordingly, the present invention solves the problem that the sealing agent is discharged by its own weight when the injection of the sealing agent is paused by providing a potting apparatus of the potting system and a method of adjusting the air pressure in the dispenser of the potting apparatus in the potting system. Can be.;Potting Device, Dispenser, Sealant, Air Intake, Solenoid Valve
