Custom Interconnect Limited (CIL) manufacture high temperature, high stress circuits for well over 20 years. They are based in Andover - in the UK. I know they are a highly approved supplier to the oil and gas business.

Our PCB laminate suppliers have not been able to provide anything which will work for more than 60 minutes at these temperatures. Can anyone recommend a product which is capable and commercially available?
