Could anyone tell me the difference in PCB material Nelco13 and FR4? PCB dielectric material Nelco13 is quite new for me and I knew nothing about it. For imcoming quality control (IQC), I am asked to identify PCB made of FR4 and Nelco13. How to do that? From which point, physical or chemical?

Thanks a lot!

Regards,

George

Nelco was developed by Park [ http://www.parknelco.com/parknelco/highspeed.htm ] Without fairly involved testing, you may be forced to rely on a c of c from your fabricator. Although, Park may be able to give you a lead.
