Yes, I thought so too - I was assuming it would have the small posts as=20
many do, or something like that. On checking the datasheet though there=20

That's our problem - I thought of doing just what you mention above, but=20
the board will have components on both sides. I have seen quite a few=20
boards (e.g. MC graphics dev boards - the link I posted previously) that=20
seem to mount directly on top of components (I am assuming they must, as=20
the display covers the entire board on a couple) I would like to know=20
how they do this (preferably without buying one for =A3100 just to have a=20
look :-)  ) and how "professional" it is.
It's not really a big deal to mount a platform a little bit above the=20
board (the design has a few boards stacked anyway to save space) but I=20
am curious about how it's done on the boards I have mentioned, and=20
DisplayTech's advice to use adhesive pads. Any simplifying of=20
parts/assembly is always a good thing.

I will ask DisplayTech for some more advice - I was hoping they had some=20
mounting accessories, but it didn't look that way when I looked on the=20
