Since the emergence of mobile phones to the present development of more than ten years, in addition to the mobile phone more and more powerful, we may also notice the change of mobile phone interface, that is, from the original single universal charger to the current form of Type-C.

USB Type-C, referred to as Type-C, is a kind of USB interface, which is loved by people with its exquisite design, fast transmission speed and large power transmission efficiency. Therefore, this interface in the production of its waterproof performance requirements and high, if its waterproof performance is not good, it is easy to cause poor interface contact, the use of the risk of leakage, directly threatening the user's life safety. Therefore, manufacturers will test its waterproofness when producing. At present, the waterproof detection method of Type-C has two methods: water detection method and air tightness detection, while the traditional water detection method has damaged the type-C interface, so we recommend using the Otto airtightness tester.

Generally speaking, due to the different waterproof levels of electronic products, the waterproof performance presented in the degree of air tightness detection is bound to be different. For the detection of electronic products, Otto is involved in a wide range of fields. Due to the small size of type-C, it is more difficult to detect, so we made a specific fixture to detect its penetration density and used an eight-channel airtight detector for detection.

Pasco's airtight test fixture: through the fixture to fix the Type-C joint, inflate it inside, through the sensor to observe whether the product's tightness is qualified, whether it meets the requirements of waterproofing, which is superior in water testing, water testing is easy to cause Type-C joint damage, with this new type of artifact - airtight machine can avoid this problem.
