Application of Mixed Flowing Gas Chamber in the Electronics Industry

One of the most effective ways to assess the durability of electronic hardware, especially in terms of corrosion resistance, is through the use of a mixed flowing gas chamber. These chambers simulate harsh environmental conditions, such as those involving corrosive gases, which electronics may be exposed to during their lifecycle.

The Importance of Mixed Flowing Gas Chambers for Corrosion Testing in Electronics Manufacturing

Corrosion is a major challenge in electronics manufacturing. When electronic components are exposed to gases such as sulfur dioxide (SO₂), hydrogen sulfide (H₂S), or chlorine (Cl₂), they can degrade, leading to potential failures. A mixed flowing gas chamber creates a controlled environment to simulate these corrosive conditions. By testing in these chambers, manufacturers can predict the corrosion behavior of their products and ensure they will function reliably in real-world environments.

These chambers are crucial tools for any manufacturer looking to guarantee the durability of their products under various conditions, from humid climates to industrial pollution. Without such testing, electronics could fail prematurely, leading to costly repairs or replacements and damage to the manufacturer's reputation.

How Mixed Flowing Gas Chambers Help Electronics Manufacturers Meet Industry Standards and Certifications?

The electronics industry must adhere to a wide range of stringent standards, particularly those related to product reliability and safety. Certifications like IEC 60068-2-60 and ASTM B845 require testing under specific corrosive conditions to ensure that products meet quality benchmarks.

Mixed flowing gas chambers help manufacturers meet these certifications by providing a standardized environment for testing. By exposing electronic components to the exact levels of gases specified in these standards, manufacturers can ensure compliance. This not only boosts consumer confidence but also helps avoid costly recalls or product failures in the field.

How to Use Mixed Flowing Gas Chamber for Electronic Component Testing?

This test chamber exposes electronic devices to a mix of corrosive gases, high humidity, and varying temperatures to evaluate the components' resistance to degradation, oxidation, and corrosion.

For instance, during a typical MFG test, a smartphone may be exposed to a gas mixture in an mixed flowing gas chamber at a concentration of 10 parts per million (ppm) for sulfur dioxide (SO₂), 5 ppm for hydrogen chloride (HCl), and 5 ppm for nitrogen dioxide (NO₂), with temperature settings ranging from 25°C to 60°C and humidity levels between 60% and 95%. The test duration typically lasts for 48 to 72 hours, depending on the product's specifications.

In a real-world scenario, a major electronics manufacturer used the MFG chamber to evaluate the performance of circuit boards. After 72 hours of exposure to mixed gases and high humidity, the test revealed that unprotected boards experienced up to a 40% increase in failure rates, particularly in solder joints and copper traces, compared to the control group. This data provided critical insights that allowed for design improvements to better shield components from environmental degradation.
