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

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.

No. That is a job for ceramic-based clad laminate. The experts in that material are Bergquist.

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?

Thanks in advance,
Paul Jackson
