Abstract

PURPOSE:To bond wires optimumly by allowing a bonding arm to make contact with a cam without delay at high speed. CONSTITUTION:An XY base is moved to place a capillary 3 on upper portion of the first pad to drive a cam 4. An output is produced to a line l1 on the basis of program 12 by a timing signal T1. Thus, a relay RY1 is operated to input a current I1 to an operational amplifier 13 so as to rotate a motor 15. Thus, the wire 10 is wound to apply tension thereto to bond the wire under pressure p1. The pressure p1 is so selected as to set p1>p0, where the p0 represents the pressure at the time of bonding ordinarily so as to sufficiently bond even if the cam 4 is rotated at transient speed. The signal T1 is released, a signal T2 is applied to the line l2 to operate a relay RY2 so as to flow a current I2 through an operational amplifier 13 so as to drive a motor to apply a load p0 thereto. With a signal T3, the middle value between the load p0 and the pressure p1 is applied thereto so that no trouble occurs even if the vibration at the time of moving the arm 1 is retained. Predetermined following weight is applied thereto except bonding time to make always the lever contact with the cam 4 to follow it to eliminate the arm 1 to undesirably vibrate. This configuration can bond the wire optimumly.
