Description

White oil sinking gold 4-layer soft and hard combination plate PCB

The 4-layer gold immersion rigid-flex PCB combines the characteristics of multi-layer structure, gold immersion treatment and rigid-flex design, with the following notable advantages:​ In terms of structure and design, the 4-layer layout provides sufficient wiring space, enabling reasonable partitioning of power, ground and signal layers to meet the integration needs of medium and high complexity circuits. The rigid-flex feature allows it to ensure overall structural stability through the rigid part, while adapting to narrow and irregular assembly spaces by virtue of the bending and folding ability of the flexible part, reducing the use of connectors and simplifying the assembly process.​ In terms of performance, the gold layer formed by gold immersion surface treatment is uniform and dense, with excellent oxidation resistance and wear resistance, which can maintain good solderability for a long time, especially suitable for high-frequency plugging or precision welding scenarios. Moreover, the gold layer has good conductivity, which can improve the signal transmission efficiency.​ In addition, the gold immersion process has high stability, which can ensure the consistency of the surface performance of the board and reduce the production defect rate. Compared with high-order multi-layer boards, the 4-layer structure makes material costs and processing difficulties more controllable under the premise of meeting performance requirements. Combined with mature rigid-flex technology, the production cycle is relatively controllable, making it suitable for mass production. It is widely used in communication equipment, precision instruments, automotive electronics and other fields.
