Flexible copper-clad laminate (FCCL), serving as the substrate material for flexible printed circuits (FPC), offers distinct advantages such as lightweight, flexibility, compact size, and excellent heat resistance. Manufacturers widely adopt it in electronic products to achieve miniaturization and portability. This approach aligns with the development trends of high-precision electronics industries such as micro-robotics, new energy vehicles, 5G communication devices,[...]

Direct answer: Flexible PCB micro-drilling requires a stack-specific approach. The most effective way to improve hole quality and micro-drill performance is to stabilize the flexible stack with rigid entry and backer materials, select drill geometry suited to polyimide and adhesive layers, and carefully control feed, speed, chip load, peck depth, and hit count. This limits the main flex-circuit drilling[...]

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[...]

With the continuous expansion of flexible printed circuit board (FPCB) applications, certain FPCBs now serve as connectors linking functional modules. Traditional FPCB plugs are prone to wear during connector interface insertion and removal, compromising electrical connection stability. Terminal crimping technology involves the sharp tip of the connector terminal piercing through the insulating material on both sides of the FPCB[...]

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[...]
