What is IEC 60068 temperature cycling ?

IEC 60068 temperature cycling is a standardized testing method used to evaluate the performance and reliability of electronic products and components under varying temperature conditions. It is an essential part of the product development and qualification process, as it helps manufacturers ensure that their products can withstand temperature changes in real-life operating environments.

The primary purpose of IEC 60068 temperature cycling is to simulate the thermal stresses that electronic products may experience during their lifetime. By subjecting the products to repeated cycles of extreme high and low temperatures, manufacturers can identify potential weaknesses or failure points and make necessary design improvements. This testing method is particularly important for products that are expected to operate in harsh environmental conditions, such as automotive electronics, aerospace systems, and outdoor communication devices.

The testing procedure typically involves the following steps:

1. Test setup: The first step is to set up the testing environment, which includes the temperature cycling equipment and the electronic products being tested.

2. Test procedures: The next step is to follow the IEC 60068 temperature cycling test procedure to subject the products to the required temperature cycles.

3. Test results: The results of the testing are then analyzed to identify any potential weaknesses or failure points in the products.

4. Defect analysis: Any defects that are identified during the testing are then analyzed and reported.

5. Design improvements: Based on the results of the testing, manufacturers can make necessary design improvements to their products to ensure that they are suitable for the intended operating environment.

In conclusion, IEC 60068 temperature cycling is a crucial testing method for evaluating the performance and reliability of electronic products and components under varying temperature conditions. By subjecting the products to repeated cycles of extreme high and low temperatures, manufacturers can identify potential weaknesses or failure points and make necessary design improvements to ensure that their products are suitable for the intended operating environment.
