A key design challenge in designing a power bank is passing EMI testing. Electronics engineers often worry about failing EMI tests. If the circuit EMI test fails many times, it will be a nightmare. You will have to work around the clock in the EMI lab to fix problems and avoid delays in product rollouts. For consumer products such as power banks, the design cycle is short and the EMI certification...
On 9th ,October, 2018, the Illuminating Engineering Society of North America (IES) released a new version of the light source color quality evaluation standard – IES TM-30-18 Method for Evaluating Light Source Color Rendition (evaluation of light source color reproduction method), with a partial update to the legacy documentation. Compared with the old version of the document released in 201...
At present, the withstand voltage tester seen on the market adopts the GB4706 (equivalent to IEC1010) standard, and the AC/DC withstand voltage and insulation resistance three-in-one withstand voltage tester with desktop structure is mostly used, which can basically meet the needs of users for testing. And most of the withstand voltage testers on the market currently use the microprocessor-control...
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...
