Copper and aluminum substrates are topics we have repeatedly discussed, at least we have learned to distinguish them, but their existence has a certain reason. Why can't the emergence of copper substrates eliminate aluminum substrates? Because their application areas and product requirements are different!

Thermal conductivity is a concern for many people: the larger the heat dissipation, the longer the lifespan, and copper substrate is the most expensive of all metals and one of the reasons for this - its thermal conductivity is as high as 300W-450W, mostly used in car headlights, taillights, and some equipment (unmanned aerial vehicles), etc; We have conducted our own experiments to prove that installing the two substrate circuit boards in a small sealed space without air vents can only

By conducting heat through its own body and connecting to the same electrical rate, it will generate heat, while copper substrates dissipate heat quickly, and aluminum substrates do the opposite. The temperature is estimated to be comparable to hot lean meat!

Aluminum's heat dissipation and thermal conductivity can only reach around 1W-2W, which is relatively low in cost, so it is mostly used in cost saving areas such as indoor lighting; I hope that through today's presentation, it can help everyone to quickly understand their two types of substrates!

Shenzhen Wuzhou Technology Co., Ltd. is a professional manufacturer specializing in the production of PCB circuit boards (aluminum substrates, copper substrates, fiberglass substrates) and SMT surface mount technology; And we have a professional LED solution R&D and design team, with a complete production chain!

The factory opened in September 2013, formerly known as Shenzhen Yili Weiye Technology Co., Ltd. In order to expand production scale, reduce production costs, and respond to the strict environmental protection measures of the Shenzhen Municipal Government, all PCB factories have been relocated to Nanzha Fourth District, Humen Town, Dongguan City, adjacent to Shenzhen. However, the marketing department is still located in Shenzhen and has a branch in Guangzhou. SMT patches are also kept in Fuyong Town, Shenzhen, making it convenient to connect with various domestic and international customers!
