12 Layer Flex Circuit Board with Book Binding

Circuit bookbinding is one of the best practices used by Rigiflex engineers for PCB design. For flex PCBs, we offer a 12 layer flex circuit board with bookbinding. An additional small length is added to the circuit, making it move in an outward direction from the bend radius. The use of this method allows the circuit to bend in only one direction.

The amount of length added is based on the number of layers in the PCB and the tightness of the bend. The advantage of circuit bookbinding is that it removes a great amount of tension from the various circuit layers during the bending process. The method also helps to prevent buckling of the circuits at the exact bend radius.
