I have done this before.
The 1st thing to do is to talk to whoever is
assembling the board.  This can be a nightmare for
them.

This application is used mainly if you only have a few
parts and are routing on one side only and don't need
vias---which would have pads on the bottom side also.
If you have vias--what is the point---no pads on the
bottom for them too??? If you are routing on one side
only--can you?---will you be using carbon ink for
overlapping routing??  Talk to your manufacturer about
this.

Usually the through hole parts are on one side and the
surface mount on the other.  We used silkscreen on
only the through hole side because we hand inserted
the parts.

I imagine this was suggested to save cost but if you
have alot of parts and routing---forget it---you
aren't saving any money.

If you do go this route--make sure the pads for the
through hole components are oversized so there is alot
of solder---don't use the standard library part.

A customer of mine wants a design done with a single
side board (copper on one side). This design has both
SMT and PTH parts, The SMT parts can't fit on the
bottom
side with the PTH pads, I guess I don't feel right
about
putting PTH parts on the same side as the pads? Has
anyone
ever did that? Thanks for any input.
