Hi,
I am looking for a cost effective and simple solution to interconnect two stacked PCBs.
The PCBs are placed on top of each other with a fixed gap of 21mm. The gap cannot be reduced as it is a fixed parameter given by the enclosure. Both PCB have component side face up.
The signal count is 2 x 20 signals TTL/CMOS logic level (address/data bus, I/O ports, I2C and SPI)
Possible solutions coming to my mind are flat ribbon cable with IDC connectors. But this is expensive as it would need to be custom made, requires additional assembly steps and crimping is error prone.
Any ideas/suggestions?
Ricky
