Abstract
The removal of connector pins from a panel, such as a printed circuit board, in which the pin extends from the panel and is soldered to a circuit member on one or both sides of the panel, is achieved by a tool positioned over the pin and having a main body member which is held in contact with the panel surface and with an axially sliding gripping member having a split gripping portion. The gripping member is moved by a tubular member surrounding the gripping member and which, on axial movement, forces the split gripping portion of the gripping member into firm frictional contact with the pin, further axial movement of the tubular member moving the gripping member and pin axially shearing the solder joint. The tubular member is moved by a pivotally mounted handle, the reaction from the pivoting of the handle and pulling on the pin holding the tool firmly against the panel. The pin is removed without damage to the panel and a new pin can be inserted and resoldered using the remaining solder at the joint.
