Characteristics of the Immersion Gold Process of PCB Surface Treatment

How important is the role of circuit boards in our lives? What I want to tell everyone is that, for us, almost everyone touches the circuit board every day, such as various electrical appliances and electronic products. However, from a PCB circuit board to the finished product, it has to go through a variety of manufacturing processes to complete. Next, let's focus on the gold-immersion process on the PCB surface. In the surface treatment of circuit boards, there is a very common process called Immersion Gold. The gold-immersion process is to deposit a nickel-gold coating with stable color, good brightness, flat coating, and good solderability on the surface of the PCB printed circuit. In addition, the PCB shows a golden yellow color after the gold is deposited. This color is more golden than the gold-plated color, because the gold is brighter and beautiful. This is the saying that the good looks can be sold at a good price. For our customers In other words, what is presented to customers is a piece of high-quality, which looks very comfortable, and customers will be more satisfied with our products; therefore, the editor summarizes its characteristics as follows: 1. The color of the gold plate is bright, and the color is bright. Okay, it looks good, and it has increased the attractiveness of customers. 2. The crystal structure formed by immersion gold is easier to weld than other surface treatments, can have better performance and ensure quality. 3. Because the immersion gold board only has nickel and gold on the pad, it will not affect the signal, because the signal transmission in the skin effect is on the copper layer. 4. Because the immersion gold board only has nickel and gold on the pads, the solder mask on the circuit and the copper layer are more firmly combined, and it is not easy to cause micro short circuits. 5. The project will not affect the distance when making compensation, which is convenient for work. Most manufacturers will receive complaints from customers because they have not been processed by the immersion gold, which results in poor welding. At the same time, it is also because the immersion gold is softer than the gold plating, so the immersion gold plate is not wear-resistant. The flatness and stand-by life of the PCB circuit board immersion gold plate are as good as the gold plate, so most factories currently use the immersion gold process to produce gold plates. PCB has always insisted on using superb technical force, sophisticated production equipment, perfect testing methods, product quality higher than industry standards, and warm and thoughtful service, which has won praise and welcome from global merchants and users.
