Maybe something like this:

Or do you want to have the daughter board sit directly in/above the socket? Then you could take the above DipPlug, without it's top and ribbon cable, and solder the tabs directly to your daughter board. Either that or your machine socket idea.

The daughter board needs to plug directly into the DIP socket in place of the chip. No cables just two rows of pins that plug into the main board DIP.

It would be more than a little work but if no other sollutions are present you can always pull the pins out of the header with plyers mount them in a drill press/dremel tool/power drill type deal and use a grinding stone to trim them down on one end so they're rounded and smaller. That's 28 pins though that's a fair amount of work, if it's a one off project probably not a bad idea.

Try flipping standard headers around, so the plastic part is on the silkscreen part of the board. That way they're not so long (depending on the thickness of the board). The only problem might be soldering them; the solder could interfere with the socket.

EDIT: Whoops, I guess you were talking about the pins being too thick. In that case, it might be good to expand on Sceadwian's idea, but make a mock router table or something to shave in one direction uniformly.

It'd be pretty simple Bob. Get the pins in the position you want in the header before you pull them out. Use a permanent marker so you know where the base of the part that extends from the plastic that will enter your socket is. Once you pull the pins out you'll have that black mark to know where to mount them in the dremel tool chuck. Spin it up and press carefully on a grinding stone. Just watch it, it's easy to grind things to a point in a dremel tool this way =) I've done this to grind toothpicks into perfect little miniature wooden stakes for a piece of scenery I made for a friends Warhammer game. Drill bit through the skull of a model miniature, insert toothpick. Little details like that add a lot to a model scene. But I digress =>

Wow and thanks for the input. It is not important enough to merit that much work.

I know we did this at one time but maybe the trick was to use a machine tool socket on the main board. I have a friend from the old days and will give him a call tomorrow.

hi 3v0 aka Bob?

These component mounting boards fit like an ic into the ic socket, same pin structure as ic.

>> IIRC regular .1 inch strip header pins are too large will ruin the DIP socket on the main board. They do from experience!
