| Project Background

The insulating substrate (usually composed of resin matrix, reinforcing materials, fillers, flame retardants, etc.) is the skeleton and insulating body of the PCB. The composition of the insulating substrate is related to electrical insulation, mechanical strength, dimensional stability, heat resistance (Tg, Td), moisture resistance, flame retardancy, coefficient of thermal expansion (CTE), etc. These properties directly affect the reliability of the PCB, the soldering yield, the long-term use stability, and the safety of the final product.

| Project Overview

The test is carried out by Fourier transform infrared spectroscopy (FTIR) and pyrolysis gas chromatography-mass spectrometry (PYGCMS). Fourier transform infrared spectroscopy (FTIR): It is good at qualitative analysis of polymer functional groups and is sensitive to the main organic components (resin type). Pyrolysis gas chromatography-mass spectrometry (PYGCMS): It is good at providing molecular information of pyrolysis products and has strong ability to identify resin types and additives (especially small-molecule additives and flame retardants).
