heavy copper flex pcb
Product Description
Heavy Copper Flex PCBs integrate thick copper conductors with flexible polyimide substrates, allowing for superior current-carrying capacity, excellent heat dissipation, and high resistance to mechanical stress and harsh environments. These boards are ideal for demanding applications such as power electronics, automotive systems, aerospace, and industrial controls. They support complex designs, tight tolerances, and full customization to meet specific requirements.

Frequently Asked Questions
Heavy Copper Flex PCB refers to a circuit board that is flexible, and has copper thickness of more than 3 oz/ft². It can carry high currents and handle thermal and mechanical stress well in flexible configurations.
Compared with standard flex PCB, heavy copper flex pcb provide higher current capacity, more effective heat dissipation and greater mechanical strength
At MOKO Technology, we support copper thicknesses of up to 5 oz for heavy copper flexible printed circuit boards.
Yes. Our heavy copper flex PCBs can withstand temperatures up to 180°C, as we use high-Tg materials and advanced thermal management techniques.
We offer turnkey PCBA ranging from component sourcing (from our partnered distributors or your BOM), bard board manufacturing, PCB assembly and quality checks.
We ship globally via DHL, FedEx, UPS, and other logistics partners. Shipping typically requires 3 to 7 days, which is decided by your geographical location.
