I would like to know the pad geometries my colleagues are using for
resistor and capacitor sizes 0603 and 0805 in relation to reflow and
wave solder.

My ops manager insisted on a deviation from IPC specs in the gap
dimension for 0603 caps.  His edict was to use 0.036 X 0.043 pads with
0.074 center to center and a gap of 0.038.  Our contract manufacturer
requested a gap of 0.040 between pads to facilitate their glue dot
dispenser.  Now, to their surprise they are having problems mounting the
caps.

Thanks in advance for all replies.
