Hi Roland I have tried what you are describing. ( dedicated PCB with conductive elastomer pads ). Bottom line: the principle works but is very sensitive and fragile and yes, expensive. You need to consider things like: Volumes to be tested, cleanliness of the product, surfacefinish of the product etc... I tooled one (high volume flipchip board, 8 mil pitch) using this approach. After a number of issues, I changed to other, more robust technologies. please contact me offline if you like more specifics.
