Many people find it strange why the USB data cable plug is easy to rust? So what is the reason? This is directly related to the electroplating layer of the plug of the USB data cable. The electroplating layer on the metal surface of the USB plug can reach the standard thickness and quality, and it will not be easy to rust. If the electroplating layer is poor, it will be easy to rust. The quality of the electroplating layer is poor. Good or bad is a measure of the ability of the metal surface to resist oxidation and rust.

The anti-oxidation and rust resistance of the electroplated layer is regulated by the salt spray test in the industry. There are conventional 8-hour salt spray test, 12-hour salt spray test, 24-hour salt spray test, and 48-hour salt spray test. . The longer the salt spray test time is, the stronger the oxidation and rust resistance will be, and it will not be easy to rust.

USB data cables are also divided into grades, which are divided into mid-to-high-end products, and the salt spray test can last for 24 hours and 48 hours. It is easy to cause the USB plug to rust. Another reason is that the electroplating layer of the plug is damaged, and the internal metal parts are exposed, which makes the USB plug very easy to rust. In order to ensure the quality, the USB data cable produced by the manufacturer also protects the USB plug. Focus on management and control. Engineers design reasonable and matched molds to ensure that the plating layer of the USB plug is not damaged during the production process, so that the USB plug will be more durable and not easy to rust.
