USB type-C, abbreviated as type C, is a type of USB interface that can be used for fast charging and efficient data transmission. Moreover, because the USB type-C interface can be easily plugged and unplugged on both sides, it has no front or back sides, making it convenient to use. Currently, more and more mobile phones are adopting the type-c interface, which supports a power output of 100W. In recent years, the USB type-c interface has also been applied from mobile phones to other devices, such as tablets, laptops, headphones, and other electronic products. If the waterproof performance is not good, there will be a risk of leakage, which will affect usage. So it is necessary to conduct airtightness and waterproofing testing on the USB type-C interface. So, how is the airtightness and waterproofing testing done on the USB type-C interface.

Due to the small and slim size of the type-c interface, as well as the grooves on the edges and internal slots of some products, there are high requirements for fixture design. Moreover, type-C has a small size and a large number of products, making it easy for the upper and lower parts to take up time. In order to improve the efficiency of airtightness and waterproofing testing of the USB type-C interface, there are 2-4 testing ports on the fixture according to requirements, which means that the airtightness and waterproofing of four USB type-C interfaces can be tested simultaneously. The airtightness and waterproofing tester equipment is a conventional waterproofing testing machine. If the USB type-c interface needs to meet the IP67 standard, then a pressure of around 10.5-20kPa can be used for testing, which can effectively ensure the quality of the USB type-c interface product.
