In many applications, miniaturisation is a must. With the FR4 Flex Board, SCHWEIZER has a sophisticated solution for realising "3D PCBs" with a bending angle of up to 180°. Thanks to the bending areas, an assembled PCB can be tailored to complicated installation conditions. FR4 Flex does this without special materials such as polyamide and without jumpers, cables, or plugs. A standard PCB is depth-milled in the bending areas and can be structured with a pattern of up to three layers in these areas.
SCHWEIZER has developed dedicated testing equipment for the qualification of the FR4 Flex technology. Extensive load tests were used to specify the maximum bending angle and the maximum permitted number of bending cycles. The values differ depending on the base material, prepreg type, thickness of the copper cladding, and temperature load profile. Please contact us! We'll find the perfect solution for your 3D challenge.
