Placement of the pin contacts<\/p>\n\n\n\n

The Concept<\/h2>\n\n\n\n

Using a dual sided 0.6mm FR4 ENIG board to create the contacts with an interiour slot for componets. Top side has no copper other than the pads<\/p>\n\n\n\n

VIA’s inside the contact to the bottom layer and then using a 0.12mm Flex board glued to the back, this will complete the the card to create a reasonable thickness of 0.72mm <\/p>\n\n\n\n

Then exposed flex area will allow for functional parts. Later it can be expoxied in. <\/p>\n\n\n\n

Something like a rpi pico chip should fit in the 0.6 profile area not exceeding the card ISO spec of 0.76mm +\/- 0.08mm<\/p>\n\n\n\n

18 Pin test points breakout on the back of the card aslo an optional usb-c pad (also usb via c4 and c8 on sim slot)<\/p>\n\n\n\n

Antenna? Possible?<\/h2>\n\n\n\n
