What Are Flexible Circuits?Issuing time:2021-07-25 18:01 They consist of conductive strips of metal, usually copper, encapsulated with an insulating dielectric material made of polyimide or a solder mask. Polyimide is an excellent insulator that allows the circuit to bend, resist contamination and withstand high temperatures. PRIME FUNCTION OF A FLEXIBLE CIRCUIT Electronic interconnection device – carries electronic signals and power Similar to a printed circuit board, yet flexible Conforms to small spaces and contoured shapes Eliminates or enables the use of smaller, less expensive connectors Provides mechanical flexing Shields radiated noise for EMI BENEFITS OF A FLEXIBLE CIRCUIT Flexible printed circuit board technology offers a multitude of possibilities for different types of products and designs. Flex is a design solution that delivers the best attributes of wire, cable, connectors and printed circuit boards – all in one interconnect solution. Reduces size and weight – a flex circuit can be up to 70% lighter than a printed circuit board Improves electronic packaging – gives designers the ability to solve packaging and interconnect issues based on the ability to form, bend and move Interconnect solution – reduces the number of interconnects (wire, cables, connectors, PCBs) Conformability – the thinness of the material allows for advanced 3-D packaging Electrical integration – tailored solutions can be created based on the myriad of material choices, plating and designs Heat dissipation/power – Polyimide dielectrics can withstand high temperatures required for a high power application Mechanical and electrical repeatability Cost savings – typically 30% to hand wiring Space savings – typically 60% Assembly savings Reliability improvements Wiring errors eliminated |
