ABSTRACT:
A solder evacuation system for removing molten solder from multiple holes in a printed circuit board. The system comprises a hollow cup assembly adapted to contact the printed circuit board. The cup assembly includes a resilient mouth adapted to contact the circuit board and encircle the molten solder area. Conduit means are connected to the cup assembly and in communication with the interior thereof. A vacuum source is connected to the conduit means and is operative for instantaneously generating a vacuum. The vacuum source comprises a hollow cylinder having a piston therein and a port to which the conduit is connected. The piston is connected to spring means which are operative when enabled to instantaneously pull the piston down the cylinder to create the vacuum. Quick-acting latch means are provided coupled to the piston to enable the piston to be withdrawn by the spring instantaneously in response to the unlatching of the latch means.
