Hi Stephen

I was interested in your comments re board failures in cycling. We have
delivered DYCOstrate pcbs to York rd that have survived over 1500 Mil
thermal cycles. Their is now a commercial version DYCOstrate-C available
which can reduce the number of layers by upto 50%, the board thickness,
improve thermal management etc if you are interested.

Details can be found at

I hope this is of Help
