Abstract
In a wire bonding apparatus that includes an air-blower connected to a compressor via an electromagnetic valve so as to provide a bonding wire with back tension by blowing air to the bonding wire, a preparatory tank which can store air is installed between the air-blower and the electromagnetic valve so as to avoid abrupt fluctuations or periodic fluctuations of the air supplied to the air-blower.
