It is BOTH a handling issue and a solder issue. For example, if a design used ONE 0.015mfd SMT
cap, how in the world would I give it to you? The cap is 0.08 x 0.05 inches, and has NO
markings!!

SMT is 99.99% robotic pick and place. Soldering is done by applying a thick paste on top of the
exposed pads, dropping the part on top, then running the pcb through a giant oven. The entire
board 'cooks' at like 400F for maybe 15 seconds. This melts the paste, the parts "plop" down due
to gravity, and the solder cools.
