What is IEC 60068-2-105:2014?

The International Electrotechnical Commission (IEC) is an international standards organization that establishes and publishes standards for various electrical, electronic, and related technologies. One of the standards it has set is the IEC 60068-2-105:2014, which focuses on the environmental testing of electronic components.

Environmental Testing of Electronic Components

Environmental testing plays a crucial role in ensuring the reliability and performance of electronic components in various operating conditions. The IEC 60068-2-105 standard specifically addresses the testing of electronic components for resistance to soldering heat, as well as thermal shock performance.

Soldering heat resistance testing aims to evaluate the ability of an electronic component to withstand high temperatures during the soldering process without experiencing any damage or degradation. The test involves subjecting the component to elevated temperatures for a specified period of time and assessing its functionality afterwards.

Thermal shock performance testing, on the other hand, assesses the capability of electronic components to withstand sudden and extreme temperature changes, which they might experience during their lifetime. This kind of testing involves exposing the component to rapid temperature transitions between high and low levels, evaluating its behavior and performance under such conditions.

Importance of IEC 60068-2-105:2014

The IEC 60068-2-105:2014 standard is important for several reasons. Firstly, it helps manufacturers ensure that their electronic components can withstand the stress of soldering processes without any adverse effects on their functionality.

Secondly, the standard allows manufacturers to design and produce electronic components that are more robust and have enhanced durability, ultimately improving the quality and reliability of electronic devices they are used in.

Moreover, complying with the IEC 60068-2-105:2014 standard enables manufacturers to demonstrate the reliability and performance of their electronic components to potential customers. This, in turn, helps build trust and confidence in the products they offer.


The IEC 60068-2-105:2014 standard plays a crucial role in ensuring the reliability and performance of electronic components under challenging environmental conditions. By providing guidelines for soldering heat resistance and thermal shock testing, this standard helps manufacturers produce robust and durable components that meet customer expectations. Adhering to this standard not only enhances the quality of electronic devices but also establishes trust between manufacturers and customers.
