The phenomenon that the 100W USB C data line plug is easy to rust is directly related to the plating layer of the 100W type C data line plug. If the plating layer on the metal surface of the USB plug can reach the standard thickness and quality, it is not easy to rust. If the coating is not good, it is easy to rust. The quality of electrodeposited coating is an index to measure the anti-oxidation and anti rust ability of metal surface.


The anti-oxidation and anti rust ability of the electrodeposited layer shall be classified by salt spray test according to industry regulations. There are 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 anti-oxidation and anti rust ability is, and it is not easy to rust.


Why is the USB data cable plug easy to rust? So what is the reason? This is directly related to the plug plating layer of the USB data cable. If the plating layer on the metal surface of the USB plug can reach the standard thickness and quality, it will not rust easily. If the plating layer is poor, it will rust easily. The quality of the plating layer is a measure of the anti-oxidation rust ability of the metal surface.

The anti-oxidation and rusting ability of Electrodeposited coatings is classified by salt spray test. There are 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 anti-oxidation and rust ability is, and it is not easy to rust.

The USB data cable produced by Yachuang electronics is also divided into medium and high-end products. The salt spray test can last for 24 hours and 48 hours. The USB plug is easy to be rusted. Another reason is that the plating layer of the plug is damaged and the internal metal part is exposed, which makes the USB plug extremely easy to be rusted. In order to ensure the quality, the USB data cable produced by the electronic data cable manufacturer is also the key control for the protection of the USB plug. The engineers design reasonable and matching molds to ensure that the plating layer of the USB plug is not damaged during the production process, In this way, the USB plug will be more durable and not easy to rust.
