Dave, I know what you mean. The first time I saw my boards soldering themselves, it was like magic…
Trust me, the magic eventually fades…I saw it over 200 times last week and it lost its appeal sometime around the 20th batch in the oven…sore back and neck and eyes from placing lots of 0603 and 0.5mm pitch components. I wish our potential pick n’ place contractor had gotten back to me after the new year but it had to get done somehow.
