In its simplest form, a flexible circuit is a vast cumulation of conductors bonded to a thin dielectric, or insulating, film. Silver or copper may be used as an electric conductor. Silver Flex Circuits are a popular alternative to Copper Flex Circuits. Silver ink conductors are added to the flexible film substrate using a screen-printing process, making it the more popular and cost-effective choice. In a Copper Flex Circuit, a very thin sheet of copper is first laminated to the flexible film substrate then chemically etched away, leaving copper traces. The etching process is not as environmentally friendly and more expensive than screen-printing silver traces. Silver Flex Circuit options include:
