Wire bonding apparatus and method

摘要

A wire bonding apparatus equipped with a chip heating assembly which is installed above a heater block that contains heaters so as to heat the chip portion of a device such as a semiconductor device, and a cooling pipe which is installed in the heater block so as to cool the heater block. The temperature of the bonding surface of the device is maintained by the chip heating assembly at a temperature that allows bonding to be executed while the heater block is cooled by cooling water or a cooling air draft that flows through the cooling pipe so that the temperature of the heater block is maintained at a low temperature that cause no softening of the resin substrate of the device.
