Double-Sided Flexible 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 (as thin as 0.075mm/3mil), 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 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
