Abstract

This gage 10 (Fig. 2) can check the accuracy of pin alignment on a semiconductor circuit module. The gage has a number of grooves 12 that are placed diagonally across all the rows of pins 14 (Fig. 1). This is done in two directions, one at a 90' rotation to the other. If the pins are within the alignment tolerance, the tool will drop down over them in both directions. If not, it will hang up on the misaligned pin.
