ABSTRACT:
A method for fabricating upright pins in a base plate, in a mutually orthogonal relationship with respect to the base plate. A first set of holes is made in a base plate at locations needed within an apparatus such as a tape cartridge. The holes are slightly oversize with respect to pins to be permanently seated therein. A second set of holes, a mirror image of the first set of holes, is made in a pin holder plate, except that the holes are not oversize. The second set of holes is adapted to hold pins in frictional contact therein. Once the pins have been disposed in the second set of holes, the holder plate is made to overlay the base plate with the outwardly facing ends of the pins brought into flush alignment with the back side of the base plate by projection through the base plate, but without the pins touching the base plate. The bottoms of the pins are now welded in place by means of a high pulse-power welding apparatus such as a laser working on the back side of the base plate. A programmed mechanical work holder may move a laser relative to pin locations and melt pins and adjacent rims of holes thereby fusing the two together, permanently attaching the pins to the base plate without distortion of either. The holder plate is then removed.
