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.
HDI Rigid-Flex PCB Manufacturing Process and Technical Challenges in Advanced Medical Electronics
An HDI rigid-flex PCB combines high-density interconnect layers with a flexible circuit, so one board can bend, fold, and carry dense signals. The high-density rigid-flex process bonds rigid and flexible materials, then uses laser via rigid-flex HDI to link fine traces across the rigid and flex zones. As a result, the board suits compact medical electronics where space[...]

PET vs FPC Selection Guide: How to Choose the Right Circuit for Thin-Film Control Panels
PET vs FPC selection determines the conductor, cost, and bend life of a thin-film control panel circuit. PET uses printed silver ink on a polyester base. FPC uses etched copper foil on polyimide. This guide compares both options by trace width, tooling, volume, and reliability, so you can pick the right build. What a Thin-Film Control Panel Circuit Must[...]
Multi-Layer FPC Manufacturing Process: Complete Step-by-Step Guide from Cutting to Testing
Multi-layer FPC manufacturing builds flexible circuits with three or more conductive layers. Plated through holes or vias connect those layers. The process runs from cutting and inner-layer imaging to multilayer FPC lamination steps, drilling, plating, coverlay, and multilayer FPC testing. This guide explains each step and the controls that protect yield. Multi-layer FPC structure What Is Multi-layer FPC Manufacturing?[...]
High-frequency FPC materials: LCP, MPI, and Low Dielectric Loss Trends (Part II)
High-frequency FPC materials are flexible circuit substrates built to keep signal loss low at GHz frequencies. They use resins with a low dielectric constant and a low dissipation factor, such as LCP, MPI, and fluororesins. This part of the guide explains how these materials differ and where each one fits. What Are High-frequency FPC materials? High-frequency FPC materials are[...]
Experimental Study on Crimp Terminals for FPCB Connectors
Crimp terminals connect an FPCB to a connector without soldering or laser welding: the terminal tip pierces the finger’s insulation and wraps the contact, creating electrical continuity through compression. This FPCB crimp terminal study tests how tool height, pressure, and crimping speed change contact resistance, pull-out force, and surface damage on the FPC finger, with the goal of identifying[...]
Boosting PCB and FPCB Heat Dissipation: Proven Engineering Methods
PCB and FPGA have two completely different performance characteristics in terms of heat dissipation. Rigid PCBs—typically built with FR-4, high-TG laminates, or metal-core substrates—offer relatively strong thermal performance due to their thicker copper layers, stable structure, and the ability to incorporate heat-spreading features such as thermal vias, copper planes, and dedicated cooling interfaces. Flexible PCBs (FPCBs), present a completely different[...]
Cutting-Edge 3D Steel Sheet Assembly Technology for Flexible PCB Applications
With the rapid advancement of technology, flexible printed circuit boards (FPCBs) have gained widespread adoption in electronic devices due to their high flexibility, bendability, and lightweight yet durable characteristics. FPCBs play a pivotal role in automotive electronics, smart wearables, smartphones, aerospace, and other fields. However, as product designs grow increasingly complex and performance demands continue to rise, 3D steel[...]
AI-Driven Optimization of Flexible Circuit Boards Production
AI-driven optimization of flexible circuit board production combines real-time sensor monitoring with closed-loop adaptive control to keep FPCB manufacturing inside narrow process windows. In AI FPCB production, the system detects deformation risks and environmental interference, then adjusts parameters before quality drifts. This approach to flexible circuit board production optimization supports high-precision manufacturing with more consistent quality and efficiency. Flexible[...]
PCB Assembly Process: A Step-by-Step Guide
The PCB assembly process (often called PCBA) is the heartbeat of modern electronics manufacturing. Transforming a bare printed circuit board (PCB) into a functional electronic assembly requires precision, expertise, and rigorous quality control. To understand this process, you need to know more than just the steps. You must also see the key differences between assembling rigid boards and the special challenges of flex PCB[...]
