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.
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 Surface Finish Types Explained: Best Options for Flexible PCBs
Introduction: Why Surface Finish Matters in PCB Fabrication Every circuit board requires protection for its copper traces. Without a reliable finish, exposed copper quickly oxidizes, reducing electrical conductivity and making soldering nearly impossible. This is why PCB surface finishes are a critical step in PCB fabrication. Surface finishes serve as a protective layer. They create a flat surface for[...]
PCB Lamination Process Explained: From Rigid Boards to Flexible PCB Manufacturing
PCB Lamination is the step that bonds copper foil, prepreg or adhesive, and a core or polyimide base into one solid board under heat and pressure. It determines layer adhesion, thermal endurance, and mechanical strength. In addition, it is the core of both rigid and flexible PCB lamination. For a flex board or a Rigid-Flex PCB, the idea is the[...]
PCB Etching Process: Flexible PCB & Rigid Flex Manufacturing
PCB Etching Process: Flexible PCB & Rigid Flex Manufacturing Introduction The etching task in PCB design is one of the most important steps in making printed circuit boards. It directly influences the precision of the circuit trails, hence performance, as well as the life of the end product. Accurate etching is important. It is used to create a standard[...]
