Air tightness testing device forelectronic component

Abstract

The invention discloses an air tightness testing device for an electronic component. The air tightness testing device comprises a sealing shell, an electric cabinet module, a carrier module, a platform frame module and a pressure head module; the electric cabinet module is arranged at the bottom of the sealing shell; a to-be-tested part is placed on the carrier module; the carrier module moves into the sealing shell; the to-be-tested part is moved to the position below a platform frame; and the pressure head module and the carrier module are aligned for air pressure airtight test. According tothe air tightness testing device, positive and negative air pressure air tightness testing can be carried out, and visualization of a testing result is achieved; the test precision is high, and the data repeatability and correlation are good; a sealing assembly is contacted with the to-be-tested part, so that the appearance damage of the to-be-tested part is reduced.

Description

technical field [0001] The invention relates to a test fixture, in particular to a device for testing air tightness of electronic components. Background technique [0002] Electronic components must have good sealing, so as to ensure waterproof and dustproof during use, so as to ensure the electrical performance of electronic components. In the prior art, the airtightness of the electronic components is generally tested by immersing them in water, that is, a special person holds the electronic components to be tested and immerses them in water, and visually checks for bubbles. If there are bubbles, it means that the airtightness is not good. Well, it is an unqualified product, and no bubbles are a qualified product. There are many defects in this kind of inspection, (1) After the inspection is completed, it is necessary to use an air gun to blow off the water, which takes about 20 seconds on average, which is time-consuming and laborious; (2) If the product leaks air but th...

In the prior art, the airtightness of the electronic components is generally tested by immersing them in water, that is, a special person holds the electronic components to be tested and immerses them in water, and visually checks for bubbles. If there are bubbles, it means that the airtightness is not good. OK, it is an unqualified product, and it is a qualified product without bubbles

There are many defects in this kind of inspection, (1) After the inspection is completed, it is necessary to use an air gun to blow off the water, which takes about 20 seconds on average, which is time-consuming and laborious; (2) If the product leaks air but the bubbles are small, it is not easy to see, and It is very easy to misjudgment due to subjective factors; (3) Electronic products generally have lubricating oil, LED lights, resistors, coils and other components inside, and immersion in water will definitely affect their reliability and service life
