I would suggest that you give your laminate supplier the PCB or sheet of
laminate that you want tested.  They will prepare the sample and run the
test.  Make sure that you specify any particular area of the cross section
that you want analyzed.

        Subject:        [TN] Tg Measurement for PWB
        Importance:     High

             Hi, ALL

             I need to measure the actual Tg of G10 & high temp FR4 by DSC
method.
             My colleague was telling me that the sample need to be made
into fine
             pieces. My question here is how the sample is prepare. Is it
right to
             include the glass fibre that is embedded in the PWB ? I would
             appreciate all your reply.

             Thanks
             CL Chong
