Flexible Circuits, commonly referred to as flex circuits, are innovative electronic components that consist of thin, flexible substrates, typically made from materials like polyimide or polyester. These circuits allow for the integration of electronic components in compact and lightweight designs, making them ideal for applications where space is limited. Flexible Circuits can bend, twist, and fold, enabling them to fit into various shapes and configurations, which is particularly beneficial in consumer electronics, medical devices, and automotive applications. They offer advantages such as reduced weight, improved reliability, and the ability to eliminate interconnection defects commonly found in traditional rigid circuit boards. |
