A tool has been developed for straightening bent module pins on semiconductor modules. The air-operated machine uses a rotating plate to straighten bent pins without contacting those that are already straight. The machine functions to move the bent module pins which do not (Image Omitted) meet specifications to the correct centerline. They are then rotated about their centers to stress relieve them prior to ending the cycle back at the zero position. Referring to Fig. 1, the pinned module 11 (pins not shown) is locked into a template 1. An offset air cylinder 2, activated by a valve 9, moves the form plate 3 to the edge of the pins, moving them to the correct centerline position. A second air cylinder 4, activated by valve 10, drives a rack and pinion 5, providing rotation to an eccentric shaft 6.
