Abstract

The present application discloses a leak detection device for a detection port of a container, which includes a detection tube, the detection tube has a fluid channel, a sealing interface and a high-pressure fluid interface located on both sides of the fluid channel, and the fluid channel is provided with There are marked fluid and high-pressure fluid, and the high-pressure fluid is formed on both sides of the marked fluid, and a transparent window is also set on the side wall of the fluid channel. The application also discloses a method for detecting the tightness of a container detection port. The invention tests the sealability through the displacement change of the symbolic fluid, has high sensitivity, can realize the non-destructive, online, real-time detection of micro-containers, and improves the reliability of micro-container sealing.

Description

technical field [0001] The invention relates to the field of sealing detection equipment, in particular to a detection device and a detection method for the detection port of a sealed container with a volume of less than 1 milliliter. Background technique [0002] In the manufacturing process of high-precision and high-performance sensors or IC devices, the sealing performance of the housing is a very important indicator. The quality of sealing performance directly affects the performance, stability and reliability of sensors or IC devices. Therefore, in the manufacturing process of sensors or IC devices, the following methods are generally used to detect the sealing performance: [0003] 1. Sampling inspection after overall sealing [0004] The entire sealed container is sampled and soaked in some kind of fluid, and then destructively detects the tightness of the detector, such as water immersion method, gas detection method, etc. This detection method has a long detecti...
