Abstract

To remove a bifurcated spring connector from a printed circuit board, it is proposed to heat the spring connector with a microflame torch. The solder around the connector tail is softened, and a hook draws the connector out of the plated thru hole while a solder sucker under the board removes the solder.

Spring Connector Removal Machine

To remove a bifurcated spring connector from a printed circuit board, it is proposed to heat the spring connector with a microflame torch. The solder around the connector tail is softened, and a hook draws the connector out of the plated thru hole while a solder sucker under the board removes the solder.

The heat is applied to the selected connector on the module side of the board using an oxy-acetylene torch with a .005-inch diameter orifice in the inserted tip. This ensures that the flame size is controlled and confined to only the defective connector. This overcomes the usual problems of not enough heat to overcome the heat sinking characteristics of the board, while not damaging adjacent connectors and/or other areas of the board.

The hook is programmed to engage the area of the connector under the spring opening and pull it out of the board. Simultaneously, a solder sucker on the wiring side of the board removes the solder from the plated thru hole. A tool can perform these functions in the correct order. This tool uses an X-Y table to locate on the connector to be removal hook on a slide comes down and removes the connector. A heated solder sucker makes contact with the bottom side of the board to remove the solder from the hole. This sequence of operations is set on timers to synchronize the whole process. The deletion site for the signal connection can be drilled to a .024-inch diameter using the original hole minus solder...
