The Function and Manufacturing Process of Immersion Gold Board
Immersion gold board, also known as immersion gold process circuit board, is a surface treatment technology. This technology mainly involves covering the surface of printed circuit boards with a layer of stretchable metal to enhance the conductivity and stability of the circuit board. Below, we will provide a detailed introduction to the functions and advantages of the immersion gold board.
Firstly, the immersion gold process can significantly improve the conductivity of circuit boards. Immersion gold treatment refers to covering the surface of a circuit board with a thin and uniform metal layer, which can effectively improve the conductivity of the circuit board, reduce resistance, and make the current flow more smoothly through the circuit board.
Secondly, the immersion gold process can also improve the stability of circuit boards. Due to the fact that the immersion gold treatment covers the surface of the circuit board with a layer of metal, it can effectively protect the circuit board from environmental influences such as oxidation and corrosion. This can greatly extend the lifespan of the circuit board and improve its stability.
In addition, the immersion gold process can also enhance the signal transmission performance of the circuit board. Due to the immersion gold treatment, the surface of the circuit board becomes smooth, which can reduce impedance and reflection during signal transmission, thereby improving signal transmission performance.
In short, the immersion gold process is a very effective surface treatment technique for circuit boards, which can significantly improve the conductivity, stability, and signal transmission performance of circuit boards. Therefore, in many high-precision and high stability electronic devices, the immersion gold process is widely used in the manufacturing of circuit boards.
The PCB board made of immersion gold technology is a type of printed circuit board widely used in electronic equipment manufacturing. This type of PCB board has high precision, high reliability, excellent electrical and mechanical properties, and is therefore widely used in fields such as communication, computer, aerospace, medical equipment, etc.
The manufacturing process of PCB boards using the immersion gold process includes the following steps:
The first step is design. According to the circuit diagram and design requirements, use professional CAD software to design and draw the circuit diagram. In the design process, it is necessary to consider issues such as the size, layout, wiring, and connection methods of the circuit board to ensure that the manufactured PCB board can meet the requirements of practical applications.
The second step is to make the mold. According to the designed circuit diagram, make the corresponding mold. The function of the mold is to copy the shape and size of the PCB board for subsequent manufacturing processes.
The third step is suppression. Stick the copper foil onto the substrate, and then use a mold to press it to the desired shape and size. During the pressing process, it is necessary to control the pressure and temperature to ensure that the pressed PCB board has accurate shape and size.
The fourth step is etching. Use a chemical solution to corrode unwanted copper foil, leaving the required circuit patterns and connections. During the etching process, it is necessary to control time and temperature to ensure the accuracy of the etched circuit patterns and connections.
The fifth step is immersion gold. Cover the circuit board with a layer of metal, usually nickel or copper, to enhance its conductivity and reliability. During the process of immersion gold, it is necessary to control the thickness and uniformity of the metal to ensure that the circuit board after immersion gold has good electrical and mechanical properties.
The final step is detection. Use professional testing instruments to test the PCB board of the immersion gold process to ensure that it meets relevant standards and design requirements. The inspection content includes appearance inspection, electrical performance inspection, mechanical performance inspection, etc.
The PCB board made of immersion gold technology is a high-quality and highly reliable electronic device component with broad application prospects and market prospects.
