Problems solved by technology

[0006] The invention provides a device for testing the airtightness of the vacuum connection board and its use method, which solves the problem that the rubber pads carved by hand are usually provided according to the sealing position of the vacuum connection boards, but the rubber pads themselves also exist. The risk of air leakage and the dimensional error of manual engraving lead to inaccurate detection of the airtight performance of vacuum connection plate products, which affects the use of later products under working conditions

Abstract

The invention provides a sealing performance testing device for a vacuum connecting plate and a using method of the sealing performance testing device. The sealing performance testing device for the vacuum connecting plate comprises four upper positioning M3 bolts, a gasket, a lower positioning airtight device bottom table and the vacuum connecting plate. According to the sealing performance testing device for the vacuum connecting plate and the use method of the sealing performance testing device provided by the invention, by virtue of a positioning form comprising four upper positioning M3 bolts and a lower positioning airtight device bottom table, the problems of difficulty in airtightness testing of the vacuum connecting plate and deviation of a detection result caused by errors of a manually-engraved rubber pad are effectively solved; the air tightness testing device for the vacuum connecting plate is matched with the sealing position of a product, four corners are positioned by screws so as to ensure the flatness of the working table, a rubber ring is designed at the contact position of the air tightness testing device and the vacuum connecting plate during air tightness testing, the air tightness testing device and the vacuum connecting plate can be in seamless contact during air tightness testing and vacuumizing, the testing effect is improved, and the detection efficiency is improved.

Description

technical field [0001] The invention relates to the field of testing the airtightness of a vacuum connection board, in particular to a device for testing the airtightness of a vacuum connection board and a method for using the same. Background technique [0002] Electronic packaging is usually used in aviation, aerospace, shipbuilding, electronics, communications, radar weapons and other fields. It is required to have excellent electrical properties and meet the functions of high reliability such as sealing, shielding, heat dissipation, support, anti-corrosion, and photoelectric transmission. Vacuum connection board is a type of hybrid integrated circuit packaging shell, generally including a metal shell, multiple leads inserted on the metal shell, and insulators that run through between the shell and the leads for high sealing and high insulation . [0003] Among them, the sealing performance is a very important performance index of the vacuum connection board. Usually, a ...
