The type A has metal on both sides of the module. The type C has plastic cover on one side. Also the A obviously has conductive strips that contact both top and bottom covers. So it is shielded somewhat from interference. C does not have the conducive strips at all. So I wonder if the placement of the C type has varying effect due to the plastic cover (facing into the unit) and something causing interference. Thoughts @nrp ? F… I didn’t see a link to the pictures and I’d like to make sure a link is available for future knowledge seekers. --- _[View the full topic](https://community.frame.work/t/guidance-on-disassembling-expansion-cards/11508)._
