  • Desoldering apparatus
    Patent number: 4412641
    Abstract: A device for desoldering electronic components from circuit boards has a soldering nozzle which produces a solder wave that is directed from below the circuit board against the component to be desoldered; thereby dissolving previous solder bonds. The component can then be lifted out from above and suction is applied from below to the now-opened bores of the circuit board, to remove residual solder from them. A new component can then be installed, using the same equipment.
