Abstract
A pin-removal tool (36) for removing a damaged or defective pin (23a) from a printed wiring board (21) includes a handle (37) and a shaft (38) extending from one end of the handle. The tool (21) further includes a sleeve (58) which is threadedly attached to the shaft (23) to facilitate rotational and axial movements therebetween. A pin-removal member (39) is fixedly attached to the shaft (38). The pin-removal member (39) includes a bore (42), a transverse slot (44) at one end of the member and a pair of shoulder-retaining portions (55) which aid in the removal of the pin (23). Laterally extending shoulders (29) of the pin (23a) are positioned within the slot (44) and the tool (36) is rotated ninety degrees to position the portions (55) adjacent to the shoulders. The sleeve (58) is then rotated while being held axially against the board 10. Upon rotation of the sleeve (58 ), the shaft (38) moves axially within the sleeve whereby the portions (55) pull the pin (23a) axially from the board (21).
