Abstract: An apparatus for holding and positioning a work piece in a desired position includes a hand-operated clamp for securing the apparatus to a fixed support, such as a table or workbench, a flexible, multi-segmented arm having one end secured to the hand-operated clamp and the opposite end pivotally secured to a vise. The vise includes a pair of jaws, a pair of essentially parallel tracks, and a screw mounted substantially parallel to said tracks. A small platform having resilient flanges snaps over and secures itself to the tracks. A number of configurations of the platform are possible depending upon the support structure of the electrical connectors or other assemblies which are being soldered or assembled. Work pieces of various shapes and sizes may be secured either to the platform or by the jaws of the vise.
