Manufacturers produce Flexible Printed Circuit Boards (FPCBs), commonly referred to as flexible circuit boards, as highly reliable printed circuit boards with exceptional flexibility, using polyimide or polyester film as the substrate material. Compared to rigid circuit boards, flexible boards offer inherent flexibility, ease of bending, lightweight properties, and thin profile advantages. Structurally, manufacturers form flexible boards by bonding a[...]

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[...]

Before mounting components via SMT, manufacturers must treat the FPC surface and solderable component ends. This ensures solderability, connection reliability, and contact reliability. The surface treatment process significantly impacts SMT placement results and may lead to issues such as soldering defects and assembly failures. Nickel-gold plating serves as an effective surface treatment method. The gold layer prevents oxidation of[...]

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 plate[...]
