In the electronics manufacturing industry, PCB (Printed Circuit Board) is one of the indispensable core components. In the PCB manufacturing process, the surface treatment process plays a vital role in the quality and performance of the circuit board. Among them, the PCB immersion gold process, namely ENIG (Electroless Nickel Immersion Gold) process, is one of the widely used surface treatment processes.

The PCB immersion gold process first plating a layer of chemical nickel on the copper surface and then plating a layer of gold to form a uniform metal alloy protective layer to improve the welding performance, anti-corrosion performance and reliability of the PCB. However, although the PCB immersion gold process can significantly improve the performance of the circuit board, in practical applications, storage time is also an issue that requires attention.

The storage time of PCB immersion gold process is affected by many factors, including environmental humidity, temperature and other factors. Generally speaking, PCB immersion gold process products can be stored for about 6 months under normal circumstances. However, if the storage conditions are not good, such as high temperature and high humidity environment, the storage time may be greatly shortened.

In order to extend the storage time of PCB immersion gold process, we can take some effective measures. The first is the correct packaging method. You can choose moisture-proof and oxidation-proof packaging materials, and package them in a vacuum or nitrogen environment to reduce the possibility of metal oxidation. The second step is regular inspection and maintenance. Regularly checking whether there are any abnormalities in the appearance of the product, discovering problems in time and dealing with them can effectively extend the service life of the product.

In order to ensure the quality and performance of PCB immersion gold process products, it is recommended to strictly control the process parameters during the production process to ensure that each process meets the standard requirements. In addition, choosing to cooperate with regular PCB immersion gold processing manufacturers is also an important guarantee to ensure product quality.
PCB immersion gold process is an important surface treatment process that can improve the performance and reliability of circuit boards, but it is necessary to pay attention to the issue of storage time during application. Through reasonable preservation and maintenance measures, you can extend the service life of your products and ensure product quality, thereby making your products more durable.
