ABSTRACT:
A connector (10) having two rows of opposed terminals (11, 12) joined by a pair of solder bars (13, 14) is mounted on a printed circuit board (16) with the terminals overlaying circuit board edge contact pads (15, 19) on opposite sides of the board. The assembled connector and circuit board is placed in a fixture whereafter pairs of comb devices are manipulated to position the comb tines between adjoining pairs of terminals. The fixture is conveyed at a fast rate in a first direction past a pair of heaters (34, 35) for preheating the two rows of terminals, the solder bars, and the circuit board pads. Next, the fixture is returned in a second opposite direction at a slow rate past the heaters to melt and thereby solder bond the comb held terminals to their corresponding board pads.
