As the core component of the product, the controller is not waterproof, which causes problems everywhere. Because the controller is waterproofly tested, the air tightness and leakage detection of the controller has become a key quality requirement for the controller. The IPX7 waterproof test is generally used.

Level, there are also IP waterproof test levels.

Do the IPX8 waterproof test of the controller. Currently, the more popular pressure drop method in the air tightness detector is used to perform the IPX8 waterproof test.

The IPx8 waterproof test is an international standard: it means that it is completely protected from the intrusion of foreign objects and dust, and can be submerged under specified water pressure indefinitely to ensure that it will not be damaged by water immersion.Since the IPX8 waterproof test level is relatively advanced, the water soaking method is

It is difficult to achieve, and it is impossible to conduct batch waterproof testing and sealing testing.At present, the more scientific method is to use an air tightness detector to conduct the IPX8 waterproof test of the controller.

How to use an air tightness leak detector to perform IPX8 waterproof testing and identification on the controller

First of all, we first understand the structure of the controller: if there is an inflation port, directly use air tightness leak testing equipment to inflate the controller and test the air leakage rate of the controller to determine whether the controller reaches the original IPX waterproof level.

Implement controller IPX8 waterproof testing.Thirdly, if the controller does not have an inflation port, you need to make a sealing detection tool, and then put the controller into the tool. The air tightness testing equipment will inflate the sealing tooling, and a gas simulation control will be used.

Depending on the environment in which the controller is used, if the sealing is not good, air will leak into the interior of the controller, thereby testing the air leakage rate of the controller and determining whether the controller has reached the original IPX waterproof level, thus achieving the IPX8 waterproof test of the controller.

This air tightness testing method is also applicable to mobile phone waterproof testing, camera waterproof testing, cavity air tightness leak detection equipment, charging pile waterproof testing, charging gun waterproof testing and other products
