Russ, The caps are 0603 case size. I am not sure about the manufacturing details, as I work for the capacitor supplier. The manufacturing details are unclear at the moment, as the customer (South of the border) has not released such detailed inform

for option 3, if you place the connectors on the first pass then flip the board, won't the protruding leads interfere with second pass stencil printing? My vote would be to overprint onto the solder mask. you can print pretty far and still have it w
