Flex Aluminum PCB

Like rigid aluminum PCBs, flexible aluminum circuit boards feature three primary layers: conductive circuitry, a flexible dielectric insulator and an aluminum base. The dielectric layer, typically composed of polyimide and ceramic fillers, has a high thermal conductivity, allowing it to pass heat from the circuitry to the aluminum base, where the thermal energy disperses. This unique design gives the flexible aluminum PCB a number of benefits, including that it’s:

• Heat transferring: The dielectric and aluminum layers give these circuit boards increased heat dispersion capabilities. The thermally conductive dielectric layer transfers heat up to 10 times more effectively than standard fiberglass designs, preventing damage from overheating and allowing circuit boards to handle stronger currents.
• Lightweight: Aluminum is a lightweight material, so flexible aluminum PCBs can provide a high performance connection in compact devices without adding impractical bulk.
• Durable: When they’re built with a flexible aluminum alloy, aluminum PCBs provide excellent strength and durability, even when they’re bent.
• Cost-effective: Because aluminum is easily mined and refined, aluminum PCBs offer a cost-effective option for managing heat in high-power circuitry. The flexibility and light weight of these circuits also helps keep overall product costs low.
