Determination of the thermal endurance of PCB FR4 epoxy laminates via thermal analyses

Popis výsledku v původním jazyce

This study evaluated new experimental parameters and end-point criteria for determining the thermal endurance of fibreglass-reinforced epoxy laminates via thermal analysis. Differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), and dynamic mechanical analysis (DMA) were used in these experiments. The composite was exposed to temperatures ranging from 170 to 200°C for times ranging from 10 to 480 hours in accord with IEC 60216. The maximum heat flow temperature (DSC Tmax) for the first thermo-oxidative reaction, the maximum weight loss temperature (DTGA Tmax), and the maximum decomposition rate were investigated. The change in the glass transition temperature after the thermal ageing was also determined using DMA. The structural changes in the samples were examined via Fourier transform infrared spectroscopy and microscopic analysis. Oxidative degradation at the surface accompanied by pyrolytic degradation in the bulk of the sample was observed. The end-point criteri
