Aluminum PCB is one of the most widely used metal core PCBs, also called as MC PCB, aluminum-clad, or insulated metal substrate, etc. The base structure of the aluminum PCB has no much different from other PCBs. The aluminum base is its notable feature. Usually, aluminum PCB includes four layers: a substrate layer (aluminum layer), a dielectric layer (insulating layer), a circuit layer (copper foil layer), and an aluminum base membrane (protective layer).
As we all know, high-temperature situations will appear when the electronics are operating at high speeds. If the thermal energy cannot be directed away quickly, the components which under high temperature may be softened, deformation, parameters changed, and performance changed, even present safety risks. Aluminum bases can remove the heat from components very soon, which allows high-density and high-power PCB designs to be achieved. The heat dissipation efficiency of aluminum PCB is ten times higher than the fiber-glass base PCBs.
If you have the problem of thermal dissipation in your PCB design, the aluminum board should be your primary consideration. YMS provides all types of aluminum PCBs including single-sided aluminum PCBs, multilayer aluminum PCBs, hybrid aluminum PCBs, flexible aluminum PCBs, through-hole aluminum PCBs, etc. Other categories, such as universal aluminum PCB, high thermal-conductive aluminum PCB, and high-frequency aluminum PCBs are also available. Please do not hesitate to contact us if you need more details about our aluminum PCBs.
High-TG PCB Advanced Circuits Specification
The glass transition temperature of PCB, referred to as “Tg”, indicates the point at which the PCB material will begin to transform. If the operating temperature exceeds the designated Tg value, the board will begin to change from a solid to a liquid state, which is likely to have an adverse effect on its ability to function.
Standard PCBs are manufactured with materials offering a TG value of 140°C, which can withstand an operating temperate of 110°C. While this may not be suitable for extreme-temperature processes that are commonplace in applications such as automotive, industrial or high-temperature electronics. In these situations, a PCB made from FR-4 High TG material can often provide the best solution.
