Genny,

Make sure the leads on any through hole components are long enough to go
through the board. There is no way to tell if they are soldered if the
tails don't come out.  I inherited a .125" thick development board
assembly with a lot of headers with short pins.  Impossible to get them
all to solder properly.  Ended up redesigning the board to finally make
the software guys stop complaining.  I won't get into why it was .125"
thick.

Subject: Thick PCB potential issues

What are the issues with thick PCB designs - PCB's that are ~0.100"
thick?
So far on my list of things to watch out for are:
	Large aspect ratios in the design
	Needing extra heat (new profiles) for SMT and potentially
pre-heat/extra heat for rework operations.

Other biggies to watch for?
