电子产品做高低温试验影响为何要做试验

The effect of high temperature and low temperature on electronic (plastic) products:

First, high temperature may cause the product to overheat, affecting the safety and reliability of use, and even damage. Such as:

1. Melting and loss of the grouting glue for insulation or sealing, melting and loss of grease, causing damage to the tower

2, the material properties change

3, the elastic or mechanical properties of the elastic components are reduced, shortening the service life of the product

4. Accelerate the deterioration and aging process of polymer materials and insulating materials, and shorten the service life of products.

Second, the impact of low temperature on machinery, electricians, and electronic products is multifaceted, and varies depending on the characteristics of the product's ability and degree of auxiliary structure, such as:

1. The electrolyte is frozen and t causes the electrolytic capacitor and battery to be used normally.

2. The viscosity of the lubricating oil increases, even the condensation freezes, which affects the starting performance of the product.

3, affect the normal start of electronic products, increase instrument error

4. Make the material brittle. For example, plastics and steel are prone to brittle fracture at low temperatures. The hardness of the rubber material increases and the elasticity decreases.
