Rigid Flex circuits are often used when components are mounted on both sides of the rigid section. Rigid Flex Issues Several approaches have been use since the 1970s for rigid flex Rigid flex can reduce overall complexity and increase reliability However, the cost for rigid flex is greater than for either rigid or flex due to a number of factors-PI flex materials more expensive than FR4 laminates (~ 3X). Balance the conductor weights and material thicknesses on each side of the neutral bend axis. Rigid flex circuits and assemblies are hybrid constructions consisting of rigid and flexible substrates laminated together into a single structure.

The thin films used in flexible circuitry offer significant width and space savings over traditional rigid designs and allow the development of printed boards that can be bent and folded in three-dimensional (3-D) configurations. Additionally, some designs may need epoxy strain relief if a bend is situated close to the rigid PCB section or the stiffener. Rigid electrical conduit is bent using machine which has a “ former “ to suit the diameter of the conduit used. For ease of ˜ exing multilayer and rigid ˜ ex designs, the use of staggered length design is commonly employed. @Allison, boots with fitting on the end avoid having to turn the flex, but they are among the worst performers. 0 Total offset in any run of flexible duct shall not exceed 90 degrees. In the case of a 90° bend, for example, the same right-angle can often be achieved with a sharp (small radius) angle or a more gradual (large radius) angle. This braided self-wrap sleeving is soft and quiet in high vibration environments.
