Introduction Flexible circuit boards, also known as flex circuits, are made of flexible insulating substrate materials that allow circuits to bend and flex without damage. Compared to traditional rigid printed circuit boards (PCBs), flex circuits can withstand repeated bending and twisting, making them ideal for use in dynamic applications where flexibility is required. Some key…

Introduction Printed circuit boards (PCBs) are essential components in nearly all modern electronic devices. They provide the physical structure and electrical connections between electronic components. While the most common type of PCB uses rigid FR-4 fiberglass as the substrate material, polyimide PCBs offer superior thermal and mechanical performance for demanding applications. Polyimide is a high-performance…
