IEC 60068-2-78 Constant Damp Heat Testing
The IEC 60068-2-78 standard specifies the procedures for constant damp heat testing, which is used to evaluate the performance and durability of materials or products under controlled environmental conditions. This test is particularly important in the semiconductor and microchip industry where reliability under extreme conditions can significantly affect product quality.
Constant Damp Heat (CDH) testing exposes specimens to a humid environment at elevated temperatures for extended periods. The purpose is to simulate real-world exposure scenarios that may cause deterioration or degradation of materials, particularly those used in electronic components such as semiconductors and microchips. This test ensures that these products can withstand moisture and heat without compromising their functionality.
During CDH testing, specimens are exposed to a constant temperature (typically 100°C) and relative humidity ranging from 85% to 93%. The duration of exposure varies depending on the product being tested but is often set at 48 hours. After exposure, the specimens are allowed to cool down before inspection for any signs of damage or degradation.
The results of this test provide critical insights into how well a given material or component will perform under conditions that could lead to failure due to moisture and heat. This information is invaluable for quality assurance processes in R&D, manufacturing, and procurement stages.
Compliance with IEC 60068-2-78 ensures that products meet international standards of reliability and safety, thereby enhancing customer confidence and meeting regulatory requirements.
Key Parameters: Temperature (100°C), Humidity (%RH), Duration (typically 48 hours).
Applications: Semiconductor manufacturing, microchip testing, electronics reliability assurance.

Scope and Methodology
The scope of IEC 60068-2-78 Constant Damp Heat Testing encompasses the evaluation of materials or products under controlled environmental conditions that simulate real-world exposure scenarios. The primary goal is to assess how well these materials or components can withstand moisture and heat without compromising their functionality.
The methodology involves exposing specimens to a constant temperature (typically 100°C) and relative humidity ranging from 85% to 93%. The duration of exposure depends on the specific application but is often set at 48 hours. After exposure, the specimens are allowed to cool down before inspection for any signs of damage or degradation.
The testing process includes careful preparation of the specimens, ensuring they represent the actual product in terms of size and composition. This ensures that the test results accurately reflect the performance of the product under real-world conditions.
Following exposure, detailed inspections are conducted to identify any changes or damages caused by the environmental stress. These inspections may include visual examinations, electrical resistance measurements, or other relevant tests depending on the nature of the specimen being tested.
The results of these inspections provide valuable insights into the durability and reliability of the product under specified environmental conditions. This information is crucial for quality assurance processes in various stages of production, from R&D to final assembly and delivery.
