We were lucky enough to be given a USB microscope this christmas so decided to try it out by soldering some Atmega8A in a TQFP32 package that we got REALLY cheap from China. We etched a breakout board using the vinyl on paper – laser print – heat transfer technique (we will write a post up about that later) and prepared to solder.
We realised they were small but hadn’t realised HOW small!
The microscope can also record video – below is our first attempt at soldering this size package. So far everything seems to have been successful!
Not the most thrilling video in the world but it works!
