Two-dimensional angstrom two-point inversion method for measuring the in-plane dynamic thermal diffusivity of flat-plate devices

This paper proposes a two-dimensional Angstrom two-point inversion method for measuring the in-plane dynamic thermal diffusivity of flat-plate devices such as vapor chambers under periodic thermal excitation. The method overcomes the limitations of steady-state thermal resistance...

A few-shot learning framework using multimodal rheological features for local prepreg thickness prediction in multilayer PCBs

As multilayer printed circuit boards (PCBs) move toward high-frequency and high-speed applications, back-drilling stub control and impedance matching have become critical for signal integrity. Their accuracy is strongly governed by the micrometer-level stability of prepreg (PP) d...
