Recently, a new breakthrough in heat dissipation technology in the field of smart mobile products has attracted much attention. China’s leading Vapor Chamber manufacturer, GDLY Electronic Materials Technology Group has successfully developed an ultra-thin soaking plate made of stainless steel with higher strength. This technology provides a new possibility to promote the development of the soaking plate in the direction of low cost. It is widely used in the manufacturing industry of smart mobile electronic products. While bringing a better user experience to consumers, it also creates a broader value- added space for industry development.
With the popularization of 5G products, the heat flux density of power devices in electronic products has become larger and larger, and the ultra-thin Vapor Chamber has become a key component for heat conduction in mobile electronic products. In smart terminal products, the use of Vapor Chamber can not only further heat the chip, battery and screen, but also improve the consumer experience.
GDLY replaces the original brazing process with the laser welding process, and can produce an ultra-thin stainless steel Vapor Chamber with a flatness less than 0.15mm. It can not only maintain good mechanical strength after heat treatment, but is also a conventional copper alloy soaking plate mechanics. Twice the strength, and the previous market’s problems with stainless steel reacting with water to produce hydrogen at high temperatures have been perfectly solved through environmentally friendly surface treatment processes.
In terms of cost, GDLY transfers the mature stamping process to the manufacturing of stainless steel upper and lower covers, replacing the conventional etching process to save costs by 20%-30%, which can better meet the needs of customers to reduce costs and improve quality. From the perspective of heat dissipation, it can also meet the conventional heat dissipation requirements, and it also shows good mass production feasibility for the super large area Vapor Chamber.
This research and development result has shown great market potential in the mobile phone and 5G ecological chain, which can not only bring greater cost space for terminal manufacturers, but also bring better consumer experience to terminal consumers.
It is worth mentioning that GDLY has also applied for multiple invention patents for this technology.
It can be said that GDLY continuously pursues breakthroughs in technology and cost in the research and development of heat dissipation products, and strives to provide customers with more and better choices. At the same time, based on continuous investment and breakthroughs in the research and development of Vapor Chamber materials, it has realized commercial production for some types of Vapor Chamber products such as ultra-thin Vapor Chamber, non-wicking Vapor Chamber, and ultra-large area and ultra-thin Vapor Chamber.
