I have had bad experiences with zebra strip style connectors. I used to do =
maintenance on a midi computer that used zebra strip style connectors to mo=
unt different style daughter boards on its serial communications I?O board.=
 The strips used were rubbery type strips with columns of graphite type stu=
ff in them, and although constrained in a plastic frame to keep them aligne=
d with the pads and vertical to the PCB they would after a while fail. You =
couldn't see any problem with them when dismantled, and cleaning the PCBs a=
nd replacing the strips for sort it out for a few months. Later on the comp=
uter manufacturer supplied a different strip that we never had problems wit=
h.

However Samtec make a connector that would fit what you want to do.

Look at the FSI range https://www.samtec.com/products/fsi three heights ava=
ilable, 3mm, 6mm and 10mm.

I investigated these a long time ago (but the project hasn't eventuated) fo=
r fitting to a daughter board when I didn't want the expense of fitting a c=
onnector on the master board, but rather some gold flashed pads using the g=
old flash of RoHS board processing.
