Abstract

PURPOSE: To detect a wire cut accurately by a method wherein an AC signal having both positive and negative polarities is impressed between a wire and an object on which it is to be bonded, and by detecting current, a wire cut is determined by the presence or absence of current.
CONSTITUTION: Bonding is operated by pressing bonding wire 5 supported by capillary 8 to semiconductor pellet 3 fixed on lead frame 4. At this time, oscillator 1, which generates a square wave signal, is placed between lead frame 4 and wire 5. While the value of current flowing in series-connected resistor 2 is checked to ±0.5mA, a current is caused to flow between frame 4 and wire 5. Further, current detector 6, which detects positive and negative current, is connected in parallel to frame 4 and wire 5, and its output is fed to flip-flop circuit 7, to which the wire cut signal is fed, and a wire cut is determined by the polarity of the current. By this, the detection can be made regardless of the direction of the pn junction of pellet 3, and the determination becomes accurate.
