So I want to make a daughterboard to fit on top of an existing circuit board.
However, there is a 12-pin MTA156 connector in the way.
I’d rather not take the connector off the board if I can help it.
The daughterboard would plug in where the EPROMs currently sit - what I’m trying to do is instead of a ribbon cable from the sockets to the existing interface board and then a second cable to the display, I want to make an updated interface board that sits on top of the logic board (using longer bolts / spacers) then deal with a single cable to the display board.
What would be the better approach? Adding a notch on the EdgeCuts layer or a series of un-plated holes? The MTA connector will not be used at all in this application.
