1L SinkPAD PCB Technology – Ultimate Solution for High-Power LED Thermal Management

- Risk of thermal runaway? – Patented copper-based direct bonding technology achieves ultra-low thermal resistance 0.8W/m·K rating.
- Select solder mask with 85% infrared emissivity.

**Assembly Process Controls‌**

- Apply solder paste with 0.12mm stencil thickness.
- Maintain peak reflow temperature at 245±5°C.
- Implement nitrogen atmosphere during reflow.

**Mechanical Integration‌**

- Allow 0.2mm expansion gap per 10°C expected temperature rise.
- Design for 5N/mm² clamping pressure with heat sinks.
- Include alignment features for ±0.1mm placement accuracy.

**Performance Validation‌**

- Measure thermal resistance from junction to board (
