2. What Is a Vapor Chamber?

A vapor chamber is a two-phase heat spreader that transfers heat by the evaporation and condensation of a working fluid.

It offers extremely fast heat spreading, low thermal resistance, and uniform temperature distribution, making it ideal for high-power, compact electronics.

3. What Is a Vapor Chamber Production Line?

A vapor chamber production line is an integrated manufacturing system designed to produce high-performance vapor chambers with consistent quality and precision. The production line typically includes the following processes:

• Copper stamping
• Groove machining
• Wick sintering
• Vacuum filling
• Laser welding
• Thermal testing and reliability inspection

The production line is optimized for high throughput, efficiency, and reproducibility in thermal performance.

4. Workflow & Manufacturing Stages

Step 1. Copper Material Preparation

• Process of cutting copper sheets
• Cleaning the copper surface
• Stamping copper or CNC forming

Step 2. Wick Structure Production

• Types of Wick:
• Sintered powder wick
• Groove wick
• Mesh wick

Step 3. Sintering

Process of heating copper powder in a sintering furnace to create porous wicking structures.

Step 4. Assembly and Bonding

Upper and lower plates are registered and prepared for welding.

Step 5. Laser Welding

Ensures leak-proof sealing of the chamber.

Step 6. Vacuum Pumping & Working Fluid Filling

Precision in gas removal and filling of the working fluid in micro-dose will ensure phase-change performance.

Step 7. Final Sealing

A second laser welding seals the chamber completely.

Step 8. Performance Testing

• Thermal resistance
• Heat spreading uniformity
• Pressure & leak test
• Reliability
