Hot pressing sintering machine for packaging high-power semiconductor device

Abstract

The invention discloses a hot pressing sintering machine for packaging a high-power semiconductor device. The structure comprises a hot pressing sintering machine, an overhaul door, a machine door, aman-machine interface and a heat radiator. The hot pressing sintering machine is composed of a machine body, a power supply device, a PLC programmable controller, a displayer and a hot pressing furnace. The PLC programmable controller can bind the wire through a wire harness mechanism so as to avoid misalignment of the wire caused by random wobbling of the wire. The wire is pressed on the conductive terminal by using the wire pressing wheel so as to avoid termination of working caused by poor contact due to the influence of external vibration on the wire during operation. When the wire is burnt out, the outer cover of the hot pressing sintering machine does not need to be disassembled and the wire does not need to be re-inserted. The servo motor drives the motor shaft to rotate, and the wire trapped under the bottom end is re-pushed into the bottom end of the wire pressing wheel by the wire feeding wheel on the motor shaft so as to save maintenance time, improve working efficiency andavoid damage to material processing.

Description

technical field [0001] The invention relates to the field of PLC programmable controllers, in particular to a hot pressing sintering machine used for packaging high-power semiconductor devices. Background technique [0002] With the rapid development of electricity, high-speed rail, and electric vehicles, the demand for high-power semiconductor devices has grown rapidly in recent years. High-power semiconductor devices have high power density and high heat generation, and their own requirements for heat dissipation are very high. And these are all done by hot-press sintering machine. The hot-press sintering machine is mainly controlled by temperature controller + voltage regulator + high-current transformer closed-loop control, automatic temperature tracking, all actions are completed by PLC, touch screen combined with PLC to complete all operations , and monitor the various operating conditions of the furnace in real time. The data of temperature, vacuum and displacement c...
