Facing obsolescence problem in FPGA based PCBs. Is it wise to mount FPGA on piggy backed board instead of assembling the FPGA directly on PCB?

Hi Goswami,

Yes, we can use piggyback boards or a socket for FPGA. In ATE testing we use sockets on load board.

You can contact Yamaichi for sockets or other vendors.

Look below links which are useful

Hi Goswami,

Sorry for the delay,

Is any specific test to be done to qualify such design on socket or piggybacked connectivity?

There is no official socket design/piggyback connectivity test specification.

You can discuss with the socket vendor directly or board design team for more input.

Intel FPGA can offers is the FPGA packaging mechanical spec in below link.
