Drop test methods and test conditions for electronic products

Date:2024-05-24 11:20:07

The drop test is mainly used to simulate the free fall that a product may experience during transportation, and to examine the product's ability to withstand unexpected impacts. The drop height is usually based on the weight of the product and the likelihood of it falling as a reference standard. The falling surface should be a smooth, hard and rigid surface made of concrete or steel (if there are special requirements, it should be determined according to the product specifications or customer testing specifications).
