**The direct answer:** Heat sinks have fins because fins exponentially increase the surface area available for convective heat transfer, allowing a compact aluminum or copper block
**Direct Answer:** Choose metal stamping for high-volume production (10,000+ parts) where dimensional consistency and low per-unit cost are critical, especially for thin-gauge mate
Thermal Vias in PCB Heat Sink Design: Best Practices and Data**Direct Answer:** Thermal vias are plated through-holes that transfer heat from a PCB's surface to an internal or exte
