Mobile phone cooling solution upgrade: 

stainless steel strip made VC soaking plate replaces copper VC soaking plate

Stainless steel material has become a choice for mobile phone heat dissipation, mobile phones are more common in the production to use stainless steel strip made VC soaking plate, from the mid-end cost-effective models to high-end folding screen models. After the VC soaking plate replaced the heat pipe design to become the core of the mainstream mobile phone cooling system, stainless steel strip made plate finally seems to have the ability to fully replace copper.

Copper plate and stainless steel strip made plate, in fact, are very common metal materials in our daily life, copper with red-orange metallic luster, has strong electrical and thermal conductivity, is widely used in a variety of electronic products; Stainless steel is usually known for corrosion resistance and rust prevention, and is widely used in a variety of daily necessities. Specifically to the VC soaking plate, in addition to poor thermal conductivity, stainless steel VC has many natural advantages compared with copper VC.

1. Stainless steel strip made VC soaking plate is essentially a piece of metal with a hollow structure, which needs to be designed and hollowed out inside, which will have a certain impact on the strength of the structure.

2. Stainless steel strip has a higher strength than copper, and can have better strength even in thinner cases, so stainless steel VC soaking plate can theoretically be made thinner and more adaptable to the highly integrated trend of smart phones.

3. Stainless steel strip has another advantage over copper: it's cheaper. This cost advantage is mainly reflected in the raw materials and processing links, on the one hand, the price of stainless steel is far cheaper than copper, on the other hand, there is more room for improvement in the process. However, with the development of the mobile phone industry, thinner and larger VC soaking boards will become an inevitable choice. It is true that it is not necessarily replaced by stainless steel, but at least it is certain that stainless steel VC soaking plate has more room for progress than copper VC soaking plate.

With the improvement of mobile phone operation efficiency, the cooling solution is replacing the existing copper VC soaking sheet by a new generation of stainless steel strip made VC soaking plate (Vapor Chamber). After the Chinese mainland mobile phone brands OPPO, vivo, Xiaomi have been imported in 2020, Samsung, Huawei and other brands have officially followed up. The first-line brand factory joined the stainless steel VC camp and became the wind.

As for the American brand factory (Apple) in the supply chain, and China's Taiwan cooling plant to seek, develop stainless steel strip made VC cooling solutions, the world's top five mobile phone brand factory full import of stainless steel VC only one member.

Supply chain said that with the upgrade of smart phone specifications, operation efficiency, copper VC soaking sheet has its physical limitations, stainless steel strip made VC soaking sheet is becoming a new favorite, compared with copper VC, in a high heat environment, stainless steel VC strength is higher, not easy to deform, warping, thermal conductivity is fast enough, in addition, in the price of raw materials, stainless steel prices are lower than copper prices. Less affected by international quotations, the relatively excellent characteristics attract major mobile phone brands to grab into the 2023 is regarded as the first year of stainless steel strip .
