You could even consider clad aluminum. But I encourage you to talk to the folks at Bergquist. Another company who has a LOT of experience in high thermal applications is Analog Technologies. They build clad copper, aluminum, and ceramic assemblies on a daily basis and are quite expert at it. We have used them to design substrates for extremely hot and harsh environments and they have done a great job at that. www.analog-tech.com -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Steven Creswick Sent: Wednesday, October 08, 2014 5:37 PM To: [log in to unmask] Subject: Re: [TN] High Temperature Laminate DBC on alumina is indeed a very good candidate, but so can hermetic HTCC [High Temp Co-fire Ceramics] and LTCC ceramics [Low Temp Co-fired Ceramics] - depending upon the power dissipated in the circuit, etc. -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Stadem, Richard D.

The experts in that material are Bergquist. -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Paul Jackson Sent: Wednesday, October 08, 2014 2:57 PM To: [log in to unmask] Subject: [TN] High Temperature Laminate Hi All, We are looking for help tracking down a copper clad dielectric capable of surviving in continuous temperatures of 200^o C - 260^o C. 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?
