Brian suggested on Facebook to watch a video on drag soldering and am I ever glad I did. I learned that I have been using the wrong tip to solder with! I went out yesterday and bought a wide flat tip for my iron, and I tried to do drag soldering exactly like I saw on youtube. Wow what a difference! I built about 18 or so REX#/REXCPM today with 100% first pass yield, and much less assembly time. very cool.
What I found was really interesting was that as you sweep the iron along the row of pins, you set up a "wave" of solder that reflows across the entire pin and pad. Wish I had figured this out ***LONG AGO***!!!! Great tip Brian. Steve
