The pins are so close together that I can't solder a wire to it, even using high-power optics and the finest soldering iron tip available. > > Are there any special tools, equipment, training, or techniques that might help with this? > > Thanks! > Wide iron tip, not narrow. You don't care if you reflow the adjacent pins, you only care about keeping the (already tinned) blue wire in the right place while the solder is wet. And like riflery or photography, hold your breath out before the delicate bit, not in. Alternatively, you may have better luck finding a via or trace that you can scrape the soldermask off with an Xacto knife than trying to hit the pins proper. -- Rob Gaddi, Highland Technology -- www.highlandtechnology.com Email address domain is currently out of order.
