Rigid-Flex PCB Project Fit<\/h2>\n

A rigid-flex PCB is appropriate when a conventional rigid PCB plus separate cable or connector creates packaging, reliability or assembly challenges. The rigid sections support components and connectors, while the flexible sections create the controlled interconnection between assemblies. The early decisions are where the flex section bends, how often it moves, how the rigid-to-flex transition is built, and which areas require impedance control or mechanical support.<\/p>\n<\/section>\n

Rigid-Flex PCB Reference Specifications for Quotation<\/h2>

These figures are reference ranges for initial rigid-flex quotation planning. They are not guaranteed in every combination. Final manufacturability depends on the rigid and flex stack-ups, bonded transition, bending condition, copper, stiffeners, via structure, panel layout and released acceptance criteria.<\/p>

Rigid-Flex PCB Design and Build Options<\/h2>\n

Rigid-flex construction typically combines FR-4 rigid areas with polyimide flex areas. Coverlay protects the flex circuit, while stiffeners can provide local reinforcement for connectors or assembly. Depending on stack-up and routing requirements, a project may use plated through holes, blind or buried vias, or microvias. Each choice affects the manufacturing route, panel utilization, electrical performance and quotation, so it should be reviewed with the released design package rather than selected from a generic specification.<\/p>\n

Projects that primarily require a bendable circuit without integrated rigid sections may be better evaluated as a Flexible PCB manufacturer<\/a> project. Dense interconnection involving microvias may also require review against the HDI PCB manufacturer<\/a> process route.<\/p>\n<\/section>\n\n
