[Analysis Case] Evaluation of Curing Degree of Polyimide Resin by FT-IR
By capturing changes in functional groups, it is possible to evaluate the imidization rate of the resin.
Resins that excel in chemical resistance and electrical insulation are used as insulators, coatings, and adhesives for various electronic components. FT-IR analysis can investigate the causes of defects such as the degree of curing of the resin, making it effective for product development. As an example, we will introduce a case where the imidization rate was evaluated from the imide groups of polyimide. It is effective for process verification by comparing the imidization rate in the insulating film on the device with data on water resistance, heat resistance, and so on. Evaluation is possible in both chip and wafer states.
