Hello all, Could somebody tell me how the measurement results differ? I vaguely recall that when measuring the same board by these two different methods, one method would show a slightly higher value than the other. But, I can't recall which one. For example, is 135 C Tg by DSC equivalent to 130 C Tg by TMA? I know there's sample and test variation, but I'm looking at results in general. And, while we're on it, which test method is your preference, especially when it comes to specification issues.
