<< 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.
