>> 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?
