In order to ensure the quality and reliability of electronic and electrical products, various reliability tests are widely adopted. Among them, packaging drop test is an important part of electronic and electrical reliability testing. This article will introduce the significance and role of packaging drop testing, and explore the precautions to be taken when conducting this test.

The packaging drop test is mainly aimed at simulating the situation of different edges, angles, surfaces, and heights falling on the ground after product packaging, in order to understand the damage situation of the product and evaluate the drop height and impact strength that the product packaging components can withstand when falling, so as to improve and perfect the packaging design based on the actual situation of the product and the scope of national standards.

The precautions for the experiment include:

1. Determination of packaging seams

The drop test of packaging is essential to find the seams of the packaging, and in fact, each packaging is very easy to judge.

2. Acceptable degree of packaging damage

Cracks or creases with a diameter of less than 20mm and a diameter of less than 50mm that penetrate the outer packaging are acceptable, but packaging damage beyond this range is not acceptable. Packaging needs to be designed to improve its drop performance. The drop test for new packaging must be repeated to verify the effectiveness of design changes.

3. Packaging placement time

For paper packaging materials, it is not acceptable to store them for a long time before conducting a drop test. It is recommended to conduct the test within 5 working days after the packaging material is produced, as paper packaging materials will absorb moisture from the air after being placed, which will affect the actual performance of the packaging.

4. Can simulated products be used instead of actual products for packaging drop

When a package can accommodate a large number of products, it may not be possible to prepare enough products to fill a package. Can similar items be used as substitutes? The answer is yes, and the corresponding principle is that the distribution of volume, weight, and weight needs to be basically consistent, and corresponding substitutes can be customized according to this standard.

5. Test interruption

The interruption time of the experimental conditions within the allowable error range is not counted as one interruption. If the interruption time of the test conditions exceeds the allowable error range, it is necessary to continue restoring the test conditions for testing to ensure that the sum of the time before the interruption and the continuous test time after restoring the test conditions after the interruption meets the test requirements. However, if there is an interruption in the experiment, it is recommended to make this experiment invalid. This experiment needs to be completely re executed, and the final result of the re executed experiment shall prevail.

When conducting packaging drop testing, many precautions need to be taken, such as selecting appropriate testing equipment, determining testing conditions and methods, preparing test samples, and recording test results. Only by strictly adhering to testing standards and procedures can the accuracy and reliability of test results be guaranteed. In addition, it is necessary to continuously explore and improve testing methods, improve testing efficiency and accuracy, to meet the constantly changing market demands and customer requirements. In the future, with the continuous development of technology and the expansion of application fields, packaging drop testing will face more challenges and opportunities. We look forward to more innovation and breakthroughs.
