Flexible Printed Circuit

A Solution to a packaging problem Flexible circuits allow unique designs which solve interconnection problems. The formability of a flexible circuit enables a package size reduction. A Flexible circuit makes installation and repair practical and cost effective. Reduce assembly costs Flex circuits can be tested prior to assembly of components. Elimination of connectors and solder joints reduce costs. Replacement for a circuit board and wires Flex circuits simplify system design. Flex circuits reduce the number of levels of interconnection required in an electronic package. Flexible circuits eliminate human error common in wire assemblies as routing is determined by artwork and repeatability is guaranteed. Reduce weight and space Considerable weight reduction is a benefit over wire harnesses. Thickness can be as thin as .004 inches (.10mm) in total. Dynamic Flexing The thinness of the material makes flex circuits the best candidate for flexible applications up to millions of flexures. Thermal management/high temperature applications. Flex circuits dissipate heat at a better rate than any other dielectric materials while providing the added benefits of vastly improved flexibility. Aesthetics Flexible circuits improve the internal appearance of an electronic package, which can have an influence on the decision making process of prospective users of the product. Category Single-side Applied with single side material to make pattern on one side then add the cover layer on the same side Double-side Applied with double sides material to make pattern on both sides then add the cover layer on each side Single-side double access double access Applied with single side material to make pattern but make some window on base film and add the cover layer on pattern top. The final products will have single layer copper but two sides access possibility Multi-layer Binding a single side and a double sides FPC together or binding a double sides and a double sides FPC together. Rigid-flex board Binding flexible and rigid boards structure together in same units as one part
