高温试验

High-temperature test

高温对产品有很多影响，如老化、氧化、化学变化、热扩散、电迁移、金属迁移、熔化、汽化变形等，通常周围环境每上升10℃，产品寿命就会减少到四分之一；当周围环境温度上升20℃，产品寿命就会减少一半，产品寿命遵循“10℃规则”，因而高温试验作为最常用的试验，用于元器件和整机的筛选、老化试验、寿命试验、加速寿命试验，同时在失效分析的验证上起重要作用。

High temperatures have numerous impacts on products, including aging, oxidation, chemical changes, thermal diffusion, electromigration, metal migration, melting, vaporization, and deformation. Typically, for every 10 °C increase in ambient temperature, the product’s lifespan is reduced to one-quarter; when the ambient temperature rises by 20 °C, the lifespan is reduced by half. Product longevity follows the “10 °C rule.” Therefore, high-temperature testing is one of the most commonly used methods, applied to component and system-level screening, aging tests, service life tests, accelerated lifetime tests, and it also plays a crucial role in validating failure analysis.

冷热冲击试验

Cold&Thermal shock test

温度冲击的试验目的是为了在较短的时间内确认产品特性的变化，以及由于构成元器件的异种材料热膨胀系数不同而造成的故障问题。这些变化可以通过将元器件迅速交替地暴露于超高温和超低温的试验环境中观察到。冷热冲击不同于环境模拟试验，它是通过冷热温度冲击发现常温状态下难以发现的潜在故障。

The purpose of temperature shock testing is to confirm, within a short period of time, the changes in product characteristics, as well as failures caused by differences in the coefficients of thermal expansion of dissimilar materials that make up components. These changes can be observed by rapidly and alternately exposing components to extremely high and extremely low temperature environments. Thermal shock differs from environmental simulation testing in that it reveals potential faults that are difficult to detect under normal temperature conditions by subjecting samples to alternating hot and cold temperature shocks.
