In view of the cable and the connector because of high frequency signal, mechanical properties, electrical properties and environment changes and other factors affecting the performance, support and consulting service so we need a complete set of test certification program and laboratory professionals, to ensure that products meet quality conditions, perfect to show the functional requirements.
USB2.0&3.0 testing and certification introduction
According to the USB Association (USB-IF) standard, the test process of USB2.0, divided into eight kinds of test categories (group). According to the different nature of the product cable and connector for discrimination, in order to receive electrical properties, mechanical properties, and environmental change of careful test. And electrical testing, mechanical testing, and environmental testing and each contains many different sub item. Therefore, the tested products will accept up to test ranging from dozens of hours to hundreds of hours. In the system of industry, the USB2.0 connector to receive hundreds of hours of environmental testing, the content includes temperature life test, the mixed gas corrosion test, thermal shock test, and the humidity test. As for the USB2.0 cable (Cableassembly), because without environmental part of the test, so the overall test time will be relatively short.
USB3.0, also known as SuperSpeedUSB, the maximum speed can support 5Gbps, so more test items. As for the USB3.0 cable not accept environmental testing, so the authentication test time is relatively not so long. In the certification standard, not all of the two ends of the connector is equipped with cable can be referred to as the USB cable, USB Association have strict rules, connector style can formulate only the USB association was seen for the USB connector. Only USB Association recognized cable category before they can send measured certification and TestID (TID).
According to the provisions of the association, any one category of item fails, the category of all items was re tested, which not only have the shipment time and money cost pressure, how to find the crux of the problem, more manufacturers care most about things. Therefore, to have a trusted partner is a very important thing. Shenzhen Chuangyi USB is the association and a variety of USB2.0&3.0 products by TID.
