2. How Thermoelectric Separation Works

The core concept of thermoelectric separation is to maintain the integrity of electrical signals while efficiently managing heat dissipation. Here’s how it works:

• Heat Source Isolation: Power components like LEDs or MOSFETs generate heat, which is channeled through dedicated thermal paths.
• Thermal Conduction Layers: A specialized thermal layer, often made of metal like aluminum or copper, directs heat away from critical components.
• Electrical Insulation: High-performance insulating materials (like FR-4 or ceramic) separate thermal paths from electrical circuits, preventing interference and maintaining signal integrity.

By designing these separate pathways, thermoelectric separation PCBs ensure that heat generated during operation is quickly and efficiently dissipated, protecting electronic components and maintaining performance.
