ABSTRACT:
A combination of laser energy and ultrasonic energy is used for soldering an insulated wire to a pad located on a substrate. The combined laser energy and ultrasonic energy strips the insulation from the wire and solders the resulting bare wire to the pad. The method has particular use for soldering insulated wire to pads located on heat sensitive substrates or to pads located in close proximity to heat sensitive devices. A principal application is for soldering fine insulated wires for connecting a thin film magnetic head to a circuit carrier substrate.
