I need to solder some Allegro 756 current sensors to PCBs. The current-carrying leads have a fairly hefty rectangular cross-section, and are designed to be soldered to relatively huge solder pads.
The obvious problem I'm facing here is trying to heat the lead and pad up sufficiently to achieve a decent solder joint without damaging the board or IC. Does anyone have any pointers for techniques that might make this job any easier? I'm not a particularly experienced solderer, but I can manage the regular-sized component leads quite well. I have a temperature-controlled soldering station and I'm using lead-free solder.
