Oops, should have said /98.
Slash sheets are better than nothing, but I always find them playing the lowest denometer and not going far enough to be a tight
description of all the material parameters that we are usually face with.
For example, Dk and Df over say 1MHz to 1GHz(or 10GHz) and at a specific resin content.
Volume and surface resistivites that are closer to real materials would be really useful for sensitive analog designs.
Best Regards

4101A/96 would be a good starting point, until 4101B comes out. Look for phenolic resin or non-dicy systems.
All the majors have newish materials. Td >= 300 is a useful metric, and I assume that all 4101B sheets will have this and Tg as
well (what about having relative moisture absorption rates?).

Subject: [TN] board material for high temp
What does everyone us for board material for High temperature solder
applications. We have a new product that will require the use of high
temperature solder. Will the use of conventional FR4 be sufficient.
