Abstract:
High-throughput DBC-assembled IGBT screening equipment for a production line is under development in order to prevent early failure of power modules. The equipment has been planning to have automatic GO/NO GO judgment technology by high-throughput measurement of current signal distribution with non-contact sensor arrays with small coils over the bonding wires of IGBT chips. Basic technology and Prototypes of a sensor, an analog amplifier, digital compensation technology, a test head and power circuit have been almost completed. The authors will fabricate the sensor arrays and develop GO/NO GO judgement technology with the integration of a basic technology.
