We have encountered issues where the quality of hole walls deteriorated during the drilling process after laminating boards with differing performance characteristics. Thermal imaging revealed temperature differentials exceeding 40\u00b0C at the material interfaces; these high temperatures destabilized the resin, thereby compromising the reliability of the copper plating. Another frequently overlooked risk is a mismatch in Glass Transition Temperature (Tg) values; after prolonged thermal cycling, micron-scale gaps can form between layers, potentially triggering Conductive Anodic Filament (CAF) issues in humid and hot environments. These critical details are particularly pertinent in high-demand applications, such as automotive electronics..."}
