Eventually, hand soldering surface mount components becomes a pain, especially if you’re doing small manufacturing runs. It’s much easier to work with solder paste and a hotplate.  Joints are higher quality, and you can manufacture more boards at once.  If it was good enough to get Sparkfun started, it’s certainly good enough for us! Working [...]

Another PCB design gets shipped off to China for manufacture! This is a tiny balloon computer.  Without battery or GPS, it weighs less than 40 grams.  It can transmit RTTY or CW at 25 mW on the ham 2M and 70cm bands, and will last up to 16 hours on a single AA. This board [...]
