In larger pad/trace (5/6 mil 20 mil pitch) designs there may not be any
fabrication issues, any smaller and the fabricator may lose the ability to
etch properly. With larger features and round pads, teardrops (or similar
pad trace interface enhancer) may be added, the ability to perform this may
drop off on square/rectangle pads of smaller size. When that happens the
fabricator runs a risk of over etching causing opens or reduced trace width.
Just some things to consider.

Was wondering what people's thoughts/opinions were about routing from
corners of pads.
Thanks,
Matt
