Abstract

Two superimposed plates 1 and 2 (Fig. 1) are supported for relatively slideable movement over one another along axis X. Plates 1 and 2 have plural identical elongated openings 1A and 2A, respectively, aligned in mirror symmetry along their respective elongated center axes CL which are parallel with axis X. Openings 1A and 2A have enlarged ends 1B and 2B, respectively, and sides that taper inwardly toward their (Image Omitted) respective smaller ends 1C and 2C. It should be understood that the plates 1 and 2 have multiple openings 1A and 2A arranged in an XY rectangular array (not shown) compatible to the pin array of the substrates being recovered. In operation:

Recovering Bent Pins on a Substrate

Two superimposed plates 1 and 2 (Fig. 1) are supported for relatively slideable movement over one another along axis X. Plates 1 and 2 have plural identical elongated openings 1A and 2A, respectively, aligned in mirror symmetry along their respective elongated center axes CL which are parallel with axis X. Openings 1A and 2A have enlarged ends 1B and 2B, respectively, and sides that taper inwardly toward their

respective smaller ends 1C and 2C. It should be understood that the plates 1 and 2 have multiple openings 1A and 2A arranged in an XY rectangular array (not shown) compatible to the pin array of the substrates being recovered. In operation:

1) The pinned substrate (Fig. 1) is put into a corner locating system (not shown) with its pins P facing upwardly.

2) The two superimposed plates 1 and 2 are next positioned over the pins P with each pair of openings 1A and 2A having its large ends 1B and 2B in concentric alignment with a particular pin P (Fig. 1). The pins P are then passed in the Z direction through the aligned larger ends 1B and 2B of the openings 1A and 2A.

3) The plates 1 and 2 are next shifted in opposite directions D1 and D2 along axis X, bringing the smaller ends 1C and 2C of the respective paired openings 1A and 2A to bear against opposite sides of the pins P in a concentric manner (Fig. 2). As a result, any bent pins P are straightened by the sliding or camming action produced between the pin...
