2. How Thermo electric separation PCB Work

1. Heat and Electrical Path Isolation

• Traditional PCBs allow heat to spread through copper traces and substrate materials, causing temperature rise and potential component damage.
• Thermoelectric separation PCBs use dedicated thermal layers to redirect heat away from sensitive components, preventing performance issues.

2. Specialized Heat Conduction Layers

• High-power components like LEDs, MOSFETs, and power modules generate significant heat, which must be efficiently dissipated.
• These PCBs incorporate metal-core (MCPCB) technology, where an aluminum or copper heat sink layer transfers heat away from the circuit.
• Thermal vias and heat-spreading techniques further improve cooling efficiency.

3. Electrical Insulation for Safety and Performance

• A dielectric insulating layer ensures electrical separation between the heat dissipation layer and signal traces.
• This prevents short circuits, leakage currents, and electrical interference, ensuring stable operation in high-frequency and high-voltage applications.
