In the present work, three diﬀerent types of copper clad laminates (FR4, CEM3 and Printed circuit boards ROGERS) were subjected to high temperature decomposition, analyzing their performance. Firstly, the samples Dioxin were analyzed by thermogravimetry, both in the absence and in the presence of oxygen in the atmosphere; FR4 Iron-clay catalyst and CEM3 showed a very strong interaction with oxygen, in contrast to ROGERS. Secondly, the laminates un- Thermogravimetry derwent oxidative pyrolysis in the presence of steam at 900 °C in a horizontal laboratory furnace; the experi-
