ABSTRACT:
A chase is arranged on a heating plate of a die set. Semiconductor packages are arranged, as products to be heated, in cavities of the chase. A runner is provided in the surface of the chase to feed a molten resin into the cavities. The heating plate has a hole for a rod-like heater and a hole for a temperature monitoring sensor. The rod-like heater is inserted into the heater insertion hole and the sensor is inserted into the sensor insertion hole. The heater has a plurality of mutually independent heat generation areas in its axial direction. The sensor detects temperature at the heat generation areas of the heater. A control section monitors the temperature near the respective heat generation areas of the rod-like heater and sets the temperature at the respective heat generation areas of the rod-like heater to a predetermined level.
