現代汽車不僅僅是代步工具,它同時具備了交通、娛樂、辦公、通訊等功能,這些功能都是由多達幾千個的電子零部件組成的復雜產品。隨著汽車產業的發展,車身控制電子、娛樂多媒體電子、導航及車載通信等電子部件越來越多,使車輛復雜程度不斷加大。而且汽車使用的環境特別嚴酷,例如各種各樣的氣候環境、污染越來越嚴重的大氣環境、顛簸復雜的路面及各種各樣的無線電干擾,都在考驗著汽車電子產品的可靠性。而這些電子零部件產品可靠性直接決定了整車的安全及運行可靠性。GST作為專業的第三方實驗室,能為汽車電子電器供應商提供專業的環境可靠性測試。
In modern times, the automobile has the functions such as entertainment, multimedia, working, communication, besides as a transportation tool. To achieve these functions, thousands of electronic components must be assembled together to form a complex product. With the development of the auto industry, the automobile is equipped with more and more electronic components including auto-body control electronic components, multimedia and entertainment electronic components, navigation system, vehicular wireless communication devices etc., which increase the complexity of the automobile. Moreover, the automobile runs in a particularly harsh environment. The various climates, atmospheric environment with serious pollution, bumpy and complex roads and a variety of radio interference are testing the reliability of the automobile electronic products. The reliability of these electronic components directly determines the safety and serviceability the automobile. As a professional third-party laboratory, GST devotes to provide professional environmental reliability testing to suppliers of automotive electronic appliances.
