Abstract
A template (148), having at least one opening (152) therein, is placed in close, spaced, relation to a PCB (30). The opening (152) is circular with a small semicircular notch (154) on the periphery thereof. A chip carrier (10) is positioned in the opening (152) with one corner (22) loosely captured in the notch (154). The PCB (30), template (148) and the loosely captured chip carriers (10) are placed in a condensation soldering facility to reflow the solder. As the solder reflows the chip carrier (10) rotates slightly about the loosely captured corner (22) to self align pads (33) on the PCB (30) to leads (16) on the chip carrier (10) as the bond is being formed.
