Rigid Flex Circuits combine the best of both rigid boards & flex circuits integrated together into one circuit. The two-in-one circuit is interconnected through plated thru holes.Rigid Flex Circuits provide higher component density and better quality control. Designs are rigid where extra support is needed and flexible around corners and areas requiring extra space.
While the design options are endless when combining rigid boards with flexible circuits, the following types of rigid flex combinations are the most common:
Eight Layer Rigid Flex
Four-Layer – A four-layer combination rigid flex circuit has four conductive copper layers. Typically, a four-layer has two flexible layers and two rigid layers.
Six-Layer - A six-layer combination rigid flex circuit has six conductive copper layers. The two most common design types are as follows:
- Six-Layer Rigid Flex: Two flex layers and four rigid layers
- Six-Layer Rigid Flex: Four flex layers and two rigid layers
Eight-Layer - An eight-layer combination rigid flex circuit has eight conductive copper layers. The two most common design types are as follows:
– Eight-Layer Rigid Flex: Four flex layers with air gap and four rigid layers
– Eight-Layer Rigid Flex: Six flex layers with air gaps and two rigid layers
