Sulfur Vapor Corrosion Chamber and Test Method for Sulfur Vapor Corrosion

Abstract

The invention discloses a sulfur vapor corrosion box and a sulfur vapor corrosion testing method. The sulfur vapor corrosion box comprises a test box body part, a sulfur vapor generation part and a parameter control part, wherein the test box body part comprises a partition plate; the partition plate is provided with a gap and is used for placing a to-be-tested sample; the sulfur vapor generation part is arranged below the partition plate and is separated from the test box body part through the partition plate for generating sulfur vapor; the sulfur vapor enters the test box body part through the gap in the partition plate; and the parameter control part is used for independently controlling parameters of the generated sulfur vapor in the test box body part.

Description

technical field [0001] The invention relates to the field of product corrosion life testing, more specifically, to a sulfur vapor corrosion chamber and a sulfur vapor corrosion testing method for product corrosion life testing. Background technique [0002] The purpose of MFG (Mixed Flowing Gas Environmental Test) is that because electronic information products, such as connectors, PC boards and some metal connection parts, will be affected by the external environment and cause corrosion and oxidation stress, resulting in poor conduction, so that The function of the product is impaired, reducing the life of the product. Therefore, an accelerated environment test becomes very important. [0003] The basic test principle is that since the coating on the surface of the copper substrate may have pinholes (Porosity), some gases in the environment, such as NO 2 , SO 2 , ... etc. will penetrate the substrate through pinholes and cause corrosion changes with copper metal, and the...

AI Technical Summary

Problems solved by technology

[0006] 2. Exfoliation corrosion is prone to occur in MFG test

[0008] 4. The maximum size of the existing MFG test box is only 800mm

Therefore, only components can be put in, and the corrosion test of the whole server cannot be carried out

[0009] 5. The test time of existing MFG is longer, such as 12-16 days

[0010] 6. The existing MFG can only be tested for one working condition

For example, when two products need to be tested in different test environments (for example, G3(Harsh) and G2(Moderate)), they need to be tested one by one, which takes longer
