Extreme heat dissipation solution in PWB stage

The original PCB was comprised of 7 layers, as shown in the sketch. Via farm holes connecting all layers were thickly copper electro-plated (35-45 μm), allowing compatibility with speedy heat-dissipation along the Z-Axis. A heat sink attached the PCB from bottom  side. The solution required extreme heat dissipation capacity in the shortest possible time.
