摘要: A device for monitoring a wire bonding process measures an electric signal applied to a bond wire during the bonding process, and generates an output which discriminates between successful and unsuccessful bonding. The device employs at least one variable parameter. The value of the variable parameter is determined beforehand in a learning process by monitoring examples of actual wire bonding operations. Thus, the detection method may adapt to changing requirements automatically and operate under optimal conditions for a large variety of circuits to be processed. The electric signal is preferably oscillating, and the measurement preferably includes its peak or RMS amplitude.

摘要: A method of monitoring a ball forming process in a wire bonder. A glow discharge parameter between an electrode on the wire bonder and an end of a wire mounted on the wire bonder on which the ball is being formed is monitored. The monitored parameter is compared with a reference value to determine whether the ball formed is satisfactory.
