Processing of customized special-shaped vapor chambers

Our company can process and customize various vapor chambers:

Capillary liquid absorbent core structure: tungsten copper powder, tungsten copper wire mesh;

Welding process: copper paste welding, diffusion welding;

Maximum size: 500*320mm;

Maximum power: 1500W;

Able to design and manufacture copper/water room temperature vapor chambers and copper/methanol low temperature vapor chambers

VC capillary structure and thickness

vapor chamber thickness

Capillary structure>=1.6mm

Rainbow copper powder+copper powder ring+copper pillar>=0.4mm

Tungsten copper wire mesh + copper powder column <=0.8mm

Sintered special copper powder <=0.8mm

Fluctuating copper wire mesh + fluctuating special copper powder

VC welding process

Welding manufacturing process characteristics application industries

Diffusion lasts for 15 years; cost is high; fixture cost is high communication/database/server,

Copper solder paste has a welding life of 10 years; low cost; low fixture cost computer/mobile phone/electronic consumption
