HELLO TECHNETTERS, DOES ANYONE HAVE ANY ADVICE ON FINDING DERATING CURVES FOR BOARD MATERIALS FR4, Chem1,Chem2 or Chem3? I AM RUNNING THERMAL TESTS ON P.C. BOARDS FOR UL QUALIFICATION AND I AM SEEING TEMPERATURES AROUND 140'c. ANY INFORMATION WOULD BE APPRECIATED GREATLY. THANK YOU FOR YOUR TIME AND CONSIDERATION. J.A.S. James A. Seamon James A.
