We are considering using Polyimide Thermount for some of our applications where in the past we have used Polyimide MLB's with Cu/Invar/Cu or Cu/Moly/Cu foils or cores to achieve CTE's in the range of 8.0 to 11.0 PPM/ degree C. Our applications are primarily for use in the military aerospace environment. I would very much appreciate hearing from PWB fabricators and users of their experiences with using Thermount. Information that I would be interested in, but certainly not limited to would be the following: Handling Storage Conditioning Processing Rework Conformal coating Testing, Thermal & Environmental CTE data Applications (end use) Applications (SMT - leaded/leadless, device types/sizes) ############################################################## TechNet Mail List provided as a free service by IPC using LISTSERV 1.8c ############################################################## To subscribe/unsubscribe, send a message to [log in to unmask] with following text in the body: To subscribe: SUBSCRIBE TECHNET <your full name> To unsubscribe: SIGNOFF TECHNET ############################################################## Please visit IPC web site (http://www.ipc.org/html/forum.htm) for additional information.
