<p>Attempt at a solderless test board for Xilinx Ultrascale+ parts in the FFVB676 package (AU10P-KU5P) and FFVE1156 (various Zynq RFSoC). I forgot a part and Digikey seems to take a few days to ship now but hopefully this will work.</p><p>Initial tests are promising with all JTAG pins having a protection diode to ground through the pressure interface.</p><p>This is 25 um polyimide with 12 um copper so very flexible. I'm backing it with 0.5 mm silicone rubber, a piece of thick metal. The stack gets clamped.</p>
