Mark,

We add .020" to the outside pad edge for all chip resistors including
0603's. Design the lands per IPC then add the extra pad. Do not change the
Z-span
of the pads. You want the extra pad on the ends to prevent shadowing. This
can also be applied to Chip capacitors, but add .030" to the edges.

S = .020"  Resistors

S = .030" Capacitors

Hello,

I am trying to come up with a footprint pattern for wave soldering 0603
components.

Does anyone out there wave solder 0603's and can you provide a land design
(that's if it is not proprietary) or direct me to where I could find that
information?

Thanks in advance.
