Mats continues his challenge of designing one PCB every week. In week 18 he came up with SMD Practice Skull:
I while ago I chatted with (Re:load) Nick Johnson about making some simple pcbs for learning how to solder smd parts. This is one of the boards that I came up with.
All parts are 1206 except for the transistors that are SOT23 so it should be rather easy to solder this even with a rather coarse tip on the soldering iron. I haven’t tested for how long the battery actually will last, but it will probably flash for a couple of days.
