Rolled Copper Foil for FPC: Improving Fold Resistance, Flatness, and Etchability
In recent years, the production of high-qu ality flexible printed circuit boards has placed higher performance demands on its key conductive material— rolled copper foil. This is particularly evident in aspects such as the foil’s fold resistance, high elongation, etchability, and low surface roughness. At the same time, higher demands have been placed on its adaptability to FPC manufacturing[...]
Pattern-Based FPC Routing Algorithm for Optimized Flexible PCB Design(Part II)
Continued part I... › Cost-Based Allocation of Routing Layers In practice, routing often involves multiple layers. Using only a single layer would result in a severe shortage of routing resources and overlook the fact that via placement is permitted in fan-out regions. Multi-Layer Routing Considerations Considering that routing paths on different layers have varying routing parameters and different impacts[...]
Innovative Flexible Circuit Manufacturing Using UV-Assisted Electroless Plating
The current manufacturing of flexible circuits primarily relies on traditional etching methods, conductive ink printing, and electroless copper plating technologies. While traditional etching is suitable for mass-customized circuit production, it suffers from issues such as pronounced side etching effects, complex process flows, lengthy production cycles, and environmental pollution from acid cleaning. These drawbacks make it difficult to meet the[...]
What is the Class-Wire Harness Flexible PCB Manufacturing Technology?
In recent years, the rapid development of high-end industries such as intelligent connected vehicles and low-altitude aircraft has driven continuous innovation in flexible printed circuit boards (FPCBs). In traditional automotive applications, certain wiring and distribution functions rely on wire harnesses, as illustrated in Figure 1. Conventional wire harnesses feature a structure where copper wires are encased in plastic insulation[...]
