Rigid-flex circuit technology is chosen when a compact or moving assembly cannot rely on a rigid board alone.
Gekunflex supports rigid-flex circuit technology from prototype to volume production, covering stack-up, coverlay, and assembly notes.
RA Copper vs ED Copper: Which Foil Fits Flexible PCB?
Compare RA copper vs ED copper for flexible PCB foil selection. See how grain structure, bend life, cost, and thickness affect FPC
Power and Energy Storage FPCs: Manufacturing Process, Materials, Trends, and Future Innovations
Power and Energy Storage FPCs are flexible printed circuits that carry current and signals in BMS units, inverters, and storage racks. They combine thin dielectrics with thick copper and protective coatings. Because space is tight, these circuits often replace round cable bundles. In addition, energy storage FPC manufacturing must control trace width, copper thickness, and bend radius for[...]

Rigid-Flex PCB for TWS Earbuds: Manufacturing Challenges and HDI Process Optimization
Rigid-Flex PCB for TWS Earbuds: Manufacturing Challenges and HDI Process Optimization A rigid-flex PCB for TWS earbuds is a circuit that combines rigid FR-4 areas for components with flexible polyimide areas for bending. The rigid wings carry the SoC, microphone, and battery contacts. The flex tail bends into the stem and nozzle. Therefore, the design removes board-to-board connectors, saves volume,[...]
Coverlay Bonding Strength in Rigid-Flex PCB: Multi-Factor Optimization Study
Coverlay bonding strength is the peel force that holds a polyimide coverlay to a rigid-flex circuit after lamination and thermal cycling. It depends on four inputs: copper surface condition, adhesive type and adhesive layer thickness, lamination pressure and temperature, and the mechanical stress the flex zone sees in service. Control all four, and peeling drops sharply. What Coverlay Bonding[...]

Research on the Manufacturing Process of Semi-Rigid Flex Printed Circuit Boards
Semi-rigid printed circuit boards form a type of rigid-flex printed circuit board (R-FPCB). The conventional rigid board manufacturing process produces them by milling or cutting out openings (windows) in areas requiring flexibility. They eliminate the need for expensive flexible materials like polyimide (PI), reducing costs while offering more stable electrical performance. These boards commonly serve in static or semi-dynamic[...]
