  • Laser soldering apparatus and method
    Patent number: 4700044
    Abstract: Fine wires are soldered without flux to solder pads on a flexible circuit of a workpiece by a laser. The laser beam is aligned and moved over the solder pad to describe a rectangle by movement of mirrors on a programmed, motor driven X-Y-Z linear table. Wires are deeply sunk into the solder pads by the weight of a cone brought against the wire carried by the X-Y-Z table. Vaporized insulation is restrained within the cone to maintain a clean microelectronic workpiece.
