Heavy copper flex PCB for maximum reliability
$23.50
MOKOPCB offers high-quality heavy copper flex PCB, which can handle high current loads while maintaining excellent flexibility. These flex circuits feature thicker copper thickness, typically 3 ounces or more. You can find that heavy copper flex circuit boards are popular in applications demanding high current capacity and precise thermal management. At the same time, the flexible structure makes them more easily integrated with complex or constrained spaces.
