Wire bonding spool system |
摘要 |
A wire dereeler for an ultrasonic wire bonder with a bond head has a support for rotatably supporting a reel of wire driven by a stepper motor in incremental steps. Two rollers receive the wire therebetween and are driven by a motor drive for rotating or torquing the rollers and tensioning the wire placed between the rollers. A linkage generally aligns the rollers in parallel with the wire therebetween. A photoelectric sensor determines a given amount of wire at a position between the bond head and the rollers and provides a signal for controlling the stepper motor driving the reel of wire.
