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.
