A TMA instrument is used to study the dimensional changes of a material as a function of temperature or time.
Depending on the measurement mode used, TMA allows you to measure:
As with TGA, a TMA instrument can be coupled to a gas analyzer for the analysis of evolved gases.
In this experiment, TMA-MS was used to identify the degradation products formed during the delamination process of a printed circuit board.
Sample: Printed circuit board (PCB) made from fiberglass with a special epoxy matrix resin
Measuring cell: TMA-MS
