simple question - how close can the uC's power pin (TQFP pad) and a ceramic cap's PTH pin can get so the PCB fabrication process or later exploitation would not go wrong ? Some ballpark figures for common equipment available in most fabrication houses are desired. uC is going to draw current from a 3.3V rail.

\$\begingroup\$ Is your question "go wrong" referring to electrical safety, or to the manufacturing process? I can't tell you how well the manual solder people can solder... that's something you have to ask them. \$\endgroup\$ – Marcus Müller Mar 14 '17 at 14:07

\$\begingroup\$ @LeonHeller Good idea, but I am the one who is going to do the hand soldering :) \$\endgroup\$ – kellogs Mar 14 '17 at 14:38
