The 14-layer immersion gold resin plugging red oil PCB board is a highly advanced printed circuit board.
It consists of fourteen layers of conductive materials and insulating substrates laminated together.
The immersion gold finish provides excellent electrical conductivity and solderability, while also
offering protection against corrosion. The resin plugging process is used to fill in holes in the PCB,
improving the board's reliability and reducing the risk of short circuits. The red oil coating provides
insulation and protection for the board's surface. This type of PCB board is commonly used in
high-performance electronics applications where reliability and performance are crucial,
such as in telecommunications, aerospace, and medical devices.
