The products must pass mechanical strength tests - vibration tests.
The concept of mechanical compatibility was introduced for testing products for transport resistance, seismic resistance of products. After transporting the packaged products, there were cases of product failures, it even got to the point that some of the radio components fell off and dangled in the interior of the product body. When the research was carried out, it was revealed that, during transportation, vibrations occur that resonate with the elements of the product and parts of the product fall off from the impact of an irresistible force.
The transport vibration is done on:
Single blows (imitation when the box was dropped from 1.5 or 3 meters)
