+ | I was mostly using 1206 footprints as most parts will fit this size and it's still posible to comfortably route between legs. 0805 is also quite universal if you design PCB. | ||
+ | For capacitors i've used "C 6032" footprint just because i've had some slightly bigger caps at the hand, but it can also take much smaller capacitors, when populated by hand. | ||
+ | |||
+ | Circuit is quite simple and it's meant just for learning of SMD soldering. It's basic 555 astable multivibrator with led and current limiting resistor: | ||
