Small / Thin Microchannel Heat Sinks with Photo Etching and Diffusion Bonding Technology

As electronic devices get more advanced and compact, their power density continues to increase, and the thermal solution comes more important. Effective heat management is crucial for ensuring product longevity. Now the small / thin heat sink demands increase to solve these issues.

What are Small / Thin Heat Sinks?

Small / thin heat sinks are cooling components designed to fit into limited spaces while providing efficient heat dissipation. These heat sinks are specially engineered for cooling small, heat-generating electronic devices, offering exceptional cooling performance despite their compact size. These heat sinks enhance the performance and durability of the devices. Such heat sinks are made possible by advanced materials and precise manufacturing techniques, which enable to create intricate internal channel structures that maximize thermal conductivity in limited spaces.

UPT’s Core Technologies Used in Small / Thin Heat Sinks

UPT designs high-performance microchannel heat sinks by combining key technologies, photo etching and diffusion bonding technology.

  • Photo etching technology: Photo etching technology is the process of using corrosive chemicals liquid to melt the specific areas on a metal sheet, and forms precise, unique and complex metal parts. This allows for the formation of complex channel structures, enhancing the thermal dissipation efficiency with the coolant.
  • Diffusion bonding technology: Diffusion bonding technology is one of bonding techniques that joints metals at atomic level by bringing their surface close together. This technique allows for creation of metal parts with complex 3D internal structures with high precision. Adhesives and spot welding are also used to bond metals commonly, but they have drawbacks such as peeling at high temperature, difficulty in cleaning, and creating gaps. The combination of photo etching and diffusion bonding technology make high cooling performance cooling plates.
