The main reasons why circuit boards use immersion gold technology are as follows:
1. Improve conductivity: The immersion gold process can form a metal protective layer, improve the conductivity of the circuit board, make the connection between electronic components more stable and reliable, and reduce signal transmission loss.
2. Improve corrosion resistance: The immersion gold process can effectively block the erosion of moisture and corrosive substances, improve the corrosion resistance of the circuit board, and extend the service life of the circuit board.
3. Improve reliability: The immersion gold process can form a uniform and dense metal protective layer, which can effectively reduce defects such as cracks and pores on the surface of the circuit board, improve the mechanical strength and impact resistance of the circuit board, and increase the service life of the circuit board. .
4. Easy to weld: The immersion gold process can form a smooth and flat welding surface, provide good welding contact, facilitate the welding process, and improve the welding quality and reliability of the circuit board.
5. Beautiful appearance: The immersion gold process can make the surface of the circuit board smoother, making it easier to produce circuit boards of various shapes and structures, and the appearance is more beautiful.
6. Improve product grade: As a high-end circuit board manufacturing process, the immersion gold process can improve the grade and value of the product, making the circuit board more in line with the needs of high-end users.
The immersion gold process can improve the conductivity, corrosion resistance, reliability, ease of welding, beautiful appearance, product quality and other advantages of the circuit board, so it is widely used in some high-end electronic products.
