Abstract

Synchronized thermography (ST) is utilized in the characterization of a flexible hybrid electronics. ST is used for both in the analysis of the structural uniformity and electrical functionality. Flexible lighting foils combining conventionally manufactured light-emitting diode (LED) chips and current regulators with a printed wiring on polyethylene terephthalate (PET) substrate were used as test samples. The measurement results proves that ST measurement method is a feasible method for the uniformity and electrical functionality characterization of large-area printed thin films with conventional electronics. ST is an interesting option to be used as a measurement tool for online quality monitoring of hybrid electronics manufacturing.
