消费电子

  • 概述 +


    消费电子产品和元件的耐光性和耐候性测试正在迅速发展。 更多种类和数量的产品是处于移动状态的,并且受到各种光源的照射,例如直接的阳光,并处于不同的气候条件。 消费电子产品OEM厂商关心的是保持品牌形象,满足客户对质量的期望。不仅功能性可能受到环境的负面影响,颜色和外观以及机械和物理性能也可能被破坏。因此,主要OEM厂商需要对新材料和设计上进行环境耐久性耐光性或耐候性测试,并在产品生命周期的整个供应链中进行验收测试。

    这种类型的耐久性测试与在不同条件下的操作和“疲劳测试”是分开的,比如在冰冻温度下进行跌落测试。相反,环境耐久性测试有助于识别在预期使用条件下过早磨损的材料问题,以及产品生命周期中的供应链问题。现在,几家主要的消费电子公司要求在全球供应链中对材料和产品部件进行耐光/耐候测试。


    可以设想若不同档次的消费电子产品和测试要求,各自拥有其独特的测试解决方案:
    • 主要用于户内的产品,如虚拟现实头显和游戏机
    • 通常在干燥环境下暴露于户外的设备,如智能手机
    • 大多在户外使用、可能会被弄湿的物品,比如健身追踪器、运动相机和无人机
    • 用于连续户外暴露的产品,如安全摄像头和户外娱乐系统
    • 可能完全或部分时间暴露于特殊环境的设备,如汽车内饰。


    可避免的问题包括:
    • 塑料、橡胶和弹性体部分发黄、开裂、褪色
    • 装饰和功能涂料的剥离、分层和外观变化
    • 液晶和OLED显示器有机化学像素元素的光降解
    • 连接线接头等金属的腐蚀
    • 日光热负载对电子产品及其外形功能特性的影响

    最后还有一个关于OLED显示器和照明的特别说明,特别是智能手机所使用的AMOLED显示屏。 由于目前材料生产技术成品率较低和批量间的差异性,Atlas Ci系列氙灯老化仪广泛使用在OLED研发和产线上用于验收不同批次的产品。

    Environmental exposures testing to the effects of light, heat and moisture are mostly performed in specialized laboratory exposure test instruments based on xenon-arc lamp technology. With the proper selection of optical filters, test specimens may be exposed to artificial full-spectrum direct sunlight, sunlight as filtered through window glass or automotive glazing, or to artificial indoor lighting, as appropriate. Temperatures, including specimen test surface temperature and moisture, as relative humidity or water sprays, provide complete simulation of specific outdoor, indoor, automotive interior, or other climatic conditions. These durability tests address the longer-term material degradation from exposure to in-service environmental stresses and are different from many of the accelerated reliability and “torture tests” that are used.


    The majority of smaller consumer electronic devices and components, including material test plaques and coupons, or sections cut from larger products, are mostly exposed for lightfastness and weather durability in Atlas Ci-Series xenon arc Weather-Ometers. These are the instruments most likely to be found in, or specified by, global consumer electronic OEM R&D and supply chain quality labs. Xenotest series instruments may also be used, especially for smaller material test coupons and plaques. Both Ci-Series and Xenotest instruments feature rotating specimen racks which move test specimens through the heat/light/moisture environment to provide the high uniformity of exposure required for product acceptance tests.

    The SUNTEST XXL+ flatbed model is useful for testing products that have more 3D dimensionality than can be accommodated in the rotating rack instruments. The UVTest is a fluorescent sunlamp device with or without condensation or water sprays, which is useful for testing thin, flat samples which are known to be sensitive only to the lower portion of the solar UV spectrum; otherwise full-spectrum xenon arc technology is recommended, especially for predicting color and appearance change.



    There currently are no international test standards specifically for consumer electronics, however several major global OEMs have established their own test criteria. While some general test standards, such as those for plastics and coatings, for example, can be used, testing of electronic products (which may be operating) often requires special conditions. Atlas has created a series of recommended test parameters for various circumstances which may be used or modified as needed.

    Metallic components such as connectors, and coatings on metal, are tested for durability in Atlas SF, BCX and CCX series corrosion test chambers. Corrosion testing services are available in Atlas’ Chicago area laboratory.



    Outdoor exposure testing in various locations, particularly for permanent outdoor electronic products, such as entertainment systems, can also be performed at Atlas outdoor exposure test sites in subtropical Miami or the Sonoran Desert in Arizona (US) or any of our more than 20 sites in our Worldwide Exposure Network. Some materials can also be exposed using concentrated natural sunlight in EMMA/EMMAQUA accelerated outdoor weathering devices.

    Laboratory exposure testing of large devices can be performed in large solar/environmental chambers at Atlas’ DSET Laboratories Arizona facility, and both xenon arc and larger product solar/environmental chamber testing is available at Atlas’ Chicago (US) area Germany commercial labs. Through proper testing, risk can be avoided.

    A variety of general international standard test methods are available for testing consumer electronics materials and products. Some are general methods while others are more specific to materials such as coatings or plastics. In addition, Atlas has developed a set of specific test recommendations which are more optimized for typical consumer electronics in-use service conditions. The following is a partial listing only of several common international test methods which may be applicable. Please consult Atlas for the specific requirements of a test method, or for recommendations for your specific needs.
