I once encountered a three-layer-thick copper design that suffered from localized overheating due to uneven via distribution, revealing that the bottleneck often lies not in the copper foil itself, but in the dielectric layers and the interlayer filling materials. By combining simplified model simulations with actual measurement data, we discovered that excessively thick copper layers can, in fact, compromise the effectiveness of thermal interface materials. We now prefer to utilize small-scale prototype testing and transient temperature rise curves to evaluate thick copper PCB designs...
