MOKO have been used in the military and aerospace industries for more than 20 years. In most rigid flex circuit boards, the circuitry consists of multiple flexible circuit inner layers selectively attached together using an epoxy pre-preg bonding film, similar to a multilayer flexible circuit. However, a multilayer rigid flex circuit incorporates a board externally, internally or both as needed to accomplish the design.
Rigid flex circuits combine the best of both rigid boards and flexible 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, we have provided you with rigid flex
combinations that are most commonly utilized.
There are many high level benefits to Rigid Flex circuits including:
Connection Reliability – Connecting rigid layers with flexible cables is the foundation for combination rigid flex circuits.
Lower Part Count – Compared to a traditional rigid board, combination rigid flex circuits require fewer parts and interconnections.
Flexible Design Options – At Flexible Circuit Technologies, we pride ourselves on taking on the most complex of design challenges. Rigid flex circuits can be designed to meet highly complex and unimaginable configurations while utilizing a rigid substrate. Rigid flex circuit designs could entail any of the following:
Highly complex configurations
Three to eight-layer combinations
High Density Applications – More often than not, the rigid component of a rigid flex circuit is utilized for high density device population. In addition, flexible circuits allow for minutely narrow lines giving way to high density device population. Denser device populations and lighter conductors can be designed into a product, freeing space for additional product features.
Package Size and Weight Reduction – Multiple systems in rigid boards create more weight and utilize more space. Combining rigid boards with flexible circuits allows for a more streamlined design thus reducing package size and weight.
In summary, if you have Rigid flex design needs, MOKO can help.
