What is ISO 60068-2-78?

ISO 60068-2-78 is an international standard that specifies methods for testing and evaluating the ability of electronic components to withstand harsh environmental conditions. This standard, titled "Environmental Testing - Part 2-78: Tests - Test Cab: Composite Dry Heat," outlines a series of tests designed to assess the reliability and durability of electronic components when exposed to high temperatures.

of ISO 60068-2-78

This standard focuses specifically on the effects of dry heat on electronic components. It aims to simulate the extreme temperature conditions that may be encountered during operation or storage and their potential impact on the performance and lifespan of the components.

The document describes various procedures for evaluating the ability of electronic components to function properly after exposure to high temperatures. These procedures include methods for determining the resistance of components to elevated temperatures and assessing any changes in performance or physical properties as a result of exposure.

Test Procedures

The ISO 60068-2-78 standard provides detailed guidelines for conducting three specific tests:

Test Db (Constant Damping Oscillation): This test involves subjecting the component to oscillations and vibrations while it is exposed to high temperatures. The purpose is to evaluate the component's ability to withstand mechanical stress under these conditions.

Test Tb (Hot Air Soak): In this test, the component is exposed to hot air in a controlled chamber. The objective is to determine whether the component's performance is affected by prolonged exposure to high temperatures.

Test Tc (Rapid Temperature Change): This test involves subjecting the component to rapid temperature changes within a specified range. It aims to assess the component's ability to withstand thermal shocks without experiencing any detrimental effects.

Benefits and Importance of ISO 60068-2-78

Adhering to the ISO 60068-2-78 standard has several benefits for electronic component manufacturers:

Quality Assurance: By subjecting their products to rigorous testing, manufacturers can ensure that they meet or exceed the required performance and durability criteria.

Reliability and Safety: The standard helps identify potential weaknesses or vulnerabilities in electronic components when exposed to high temperatures, enabling manufacturers to make necessary improvements to enhance reliability and safety.

Marketability: Complying with international standards like ISO 60068-2-78 gives manufacturers a competitive edge by demonstrating their commitment to producing high-quality and robust products.

Ultimately, ISO 60068-2-78 serves as a valuable tool in enhancing product quality, improving customer satisfaction, and fostering innovation in the field of electronic components.
