•IPC 6013, MIL-P-50884 - Type 4•Two or more conductive layers with either flexible or rigid insulation material as insulators between each one; outer layers may have covers or exposed pads.•Rigid-flex has conductors on the rigid layers, which differentiates it from multilayer circuits with stiffeners. Plated through-holes extend through both rigid and flexible layers (with the exception of blind and buried vias). Rigid-flex costs more than a standard circuit with stiffeners.•Access holes or exposed pads without covers may be oneither or both sides. Vias or interconnects can be fully covered for maximum insulation.•Stiffeners, pins, connectors, components, heat sinks, and mounting brackets are optional. •We also manufacture “flush”rigid-flex, where the top surface of contact areas is level with adjacent adhesive/insulation.•Minco is capable of sequentially laminating, drilling, and plating circuits, which allowsfor more flexibility in designing the circuit.

Flex-Coils are flex circuits containing integral wire coilsfor use as antennas or inductors. There are three basic types of Flex-Coils:•Simple, flat coils with wire leads •Coils laminated inside flex circuits •“Rim”coils that are built up in the Z-axisFlex-Coils have the same advantages that a flex circuit does. Wiring errors are reduced because the coil is oriented in the same spotevery time, which provides repeatable signals. Flex-Coils are rugged and easy to assemble, and their design usually guarantees areduced package size. A Flex-Coil can terminate in any manner that a flex circuit can, or to a wire lead. Heavy wire leads are available.See Flex-Coils™ Technical Specification FC01, for more information on Flex-Coil capabilities, design considerations, and the informationrequired for a quote or build.
