Double-Sided Flex PCB (Flexible Printed Circuit Board) refers to a highly reliable and customizable solution designed for compact and dynamic electronic applications. These circuit boards feature two copper layers on either side of a flexible polyimide (PI) or polyester (PET) substrate, enabling complex routing and high-density interconnects through vias.

Key advantages include lightweight, thin profile, and mechanical flexibility, making them ideal for wearable devices, consumer electronics, and aerospace applications where space constraints and durability are critical. The dual-sided design allows for increased component density and improved EMI performance, while advanced manufacturing processes ensure precise trace dimensions (as small as 0.075mm/3mil) and reliable soldering interfaces. As the demand for flexible electronics grows, Double-Sided Flex PCBs remain a cost-effective alternative to rigid PCBs and multilayer FPCs for medium-complexity designs.
