The early products were named electronic products mainly based on electronic tubes. Leak testing, as the name implies, refers to testing the leak of a sample for leak. The application field is wide. The method is suitable for detecting the sealing performance of packaging bags, boxes, bottles, cans and the like in the industries of military industry, food, medical instruments, chemical industry, automobiles, electronic components, storage and the like. It is also possible to test products which have sealing requirements themselves. The sealing can be divided into static sealing and dynamic sealing. The static seal mainly comprises pad seal, sealant seal and direct contact seal. The static seal can be divided into medium-low pressure static seal and high pressure static seal according to the working pressure. The medium and low pressure static seal is usually sealed by a cushion made of a softer material and wider in width, and the high pressure static seal is sealed by a metal gasket made of a harder material and narrower in contact width. Dynamic seals can be divided into two basic types, rotary seals and reciprocating seals. Whether other parts which move relatively to the sealing element are contacted or not can be divided into contact type sealing and non-contact type sealing; depending on the sealing element and the contact position, these can be further divided into circumferential sealing and end face sealing, which are also referred to as mechanical seals. Centrifugal sealing and spiral sealing in dynamic sealing are sometimes called dynamic sealing because they are sealed by applying power to a medium when a machine is operated.
At present, electronic products have higher and higher requirements on the sealing performance, the sealing performance of the products is always required to be detected before the electronic products in the same batch leave a factory, if the traditional bubbling detection method is adopted for detection, the products are basically scrapped once the detected products have the side leakage condition, and the detection cost is higher, so that a sealing performance detection method which does not damage the internal components of the products is urgently needed.
