continuous piece. Long assemblies of this type may be employed as replacements for complex multibranch EWIS wiring in commercial and military aircraft. Double-sided flex circuits Double-sided flex is also supplied to expand available circuit real-estate within the same basic envelope as a single-sided assembly. Connector terminations for double sided flex include straddle-mount designs for interconnection to conductive pads on both sides of the flexible dielectric film. Multilayer flex circuits Multilayer flex is supplied for applications that need three or more layers of conductors for termination to higher pin-count circular and multi-row rectangular connectors. These assemblies support their higher circuit density with bonded conductive layers that are interconnected with selectively plated through- holes called “vias.” Glenair can support up to 8 such layers in a conventional multilayer flex circuit build. Rigid-Flex circuits Rigid-Flex Circuits are hybrid constructions that consist of flexible circuit assemblies, laminated together with rigid board elements. Rigid-Flex circuits are used for surface mounting of electronic components or to provide strengthening or mounting features to the flex assembly. Glenair manufactures numerous variations of rigid-flex, including multi-layer assemblies with up to 27 layers. Rigid-Flex assemblies are also uniquely employed on flex-to-install designs that combine embedded PCB boards and flex circuitry. Supported connector terminations include thru hole, straddle, surface mount, and ZIF. Substrate options include DuPont ™ Kapton ® and Panasonic Felios.
Optical Flex Circuits Glenair optical flex
circuit assemblies are lighter weight, higher density replacements for conventional fiber wire assemblies. Typically
integrated with high-density MT ferrule terminations, the assemblies are designed for use with optical backplanes and card- to-card applications. Glenair optical flex circuit support singlemode, multimode, and specialty fiber as well as hybrid optical and electrical configurations that integrate the two technologies in multilayer assemblies. The principal design benefit of optical flex circuitry is the ability to implement fiber crossing or shuffle circuitry for the complex routing of fiber lines inside control computers and other types of LRUs. Glenair optical fiber circuit assemblies offer reduced installation time and termination errors, reliable, repeatable performance, superior optical fiber management, controlled low-skew routing lengths, controlled bend radii minimizing bend loss, and long length leads 12 inches and up, eliminating the need for splicing within an equipment enclosure. Glenair long-length leads are far more durable that conventional fiber ribbon cable when used in support of MT ferrules and connectors. For all assemblies, Glenair builds in accordance with the IPC-6012/6013 specification standard, although Military customers may alternatively cite specifications IAW MIL-PRF-31032. In both cases, we recommend leveraging our design team for optimization of connector pin-outs to reduce frequency of cross-overs that lead to higher layer counts and increased cost. Our application design and prototyping services are free and highly available.
