Uncontrolled environmental conditions, such as temperature and humidity, may be achieved in an Environmental Chamber, which is an enclosed chamber. By delivering salt spray within the chamber, certain chambers may also imitate rusting. Temperature chambers enable manufacturers to check test their goods in a controlled environment before shipping them. This chamber’s size might vary substanti...
Hazards in industry: The generation of static electricity is inevitable in industrial production, and the hazards caused by it can be attributed to the following two mechanisms: 1. Hazards caused by electrostatic discharge (ESD): cause malfunction or malfunction of electronic equipment and cause electromagnetic interference. 2. Breakdown of integrated circuits and precision electronic components, ...
Fundamentals and Harmonics In complex periodic oscillations, both fundamental and harmonics are involved. The sine wave component equal to the longest period of the oscillation is called the fundamental wave. The frequency corresponding to this period is called the fundamental frequency. The components of a sine wave whose frequency is an integer multiple of the fundamental frequency are called ha...
For Windows 7/8 USB driver coding, Microsoft explicitly requires drivers to use EV code signature, and after Windows 10/11, the EV coding signature is not enough but need to submit to Windows Hardware Development Center Dashboard to get Microsoft code signature, or the USB driver can’t be run in the newest Windows 10/11 (see Fig 1) even you Disable Digital Driver Signature Enforcement. Fi...
As the speed of integrated circuits is getting faster and the density is getting bigger and bigger, there will inevitably be interference problems, and we must solve this interference. Why should integrated circuits pass EMI/EMC testing? Strictly speaking, all electronic devices require EMI/EMC testing. Electronic devices with excessive EMI/EMC not only work unstable, but also affect other electro...
In the field of environmental testing, and the environmental chamber is a device that enables users to manipulate the ambient conditions in an enclosed space to perform controlled testing on a topic. Researchers, engineers, scientists, and manufacturers make use of these favourable conditions to stimulate innovation and ensure that the products they produce are safe for customers to use. Because o...
RoHS testing stands for Restriction of Hazardous Substances. First implemented as a European Union regulation in 2003 (2002/95/EC), the RoHS test has become an international standard. 2011 saw the implementation of a new RoHS directive (2011/65/EU). RoHS 2 is the official name of this new rule. RoHS broadened the scope of the regulations to include all EEE, cables, and replacement parts of any kin...
UV test also known as UV aging test which is a process of simulating the various factors involved in the actual use of the product to carry out corresponding conditions to strengthen the experiment on the aging of the product. The UV aging test experiment is mainly for plastic materials, and the common aging mainly includes light aging, damp heat aging, hot air aging. The ultraviolet aging test ch...
Vibration test is to simulate the various vibration environment impacts encountered by the product in the transportation, installation. This test is to simulate the various impacts encountered by the product in the transportation, installation and use environment. This kind of vibration environmental impact is used to determine whether the product can withstand various environmental vibrations. Vi...
