Pins for Low Temperature PCB

id the sloth

I am not sure if this is the right place to post this, but I was hoping I could get some help from the forums. I am working on a project that requires us to custom make PCB boards for an experiment. I am trying to find pins and receptacles for the PCB, gold-plated ones that will work at liquid Helium temperatures. Every where I have looked, I have found places with large minimum orders when we only need 100 or so pins. I have been looking for a while and was hoping I could get some guidance from someone on the forums. I cannot be the first person who has done this. Any input would be more than welcome!
