Is there any place to get information on various types of laminate to find out such parameters as DK, CTE, Loss Tangent, Tg, etc. Need to determine what type of laminate I can use for RF products which will be the cheapest but still work. For example, need to build a matrix of materials such as standard Fr4, BT, PTFE, Rogers 4003, Nelco4000-13, etc.. etc, . Would take a long time to get this info from each laminate vendor and I do not have much time. thanx.... ############################################################## 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.
