RoHS (Restriction of certain hazardous substances directive) is a European regulation aiming to restrict the use of hazardous substances in electronic and electrical equipment. To ensure that products meet RoHS requirements, a RoHS tester has become an important RoHS testing tool. This paper will discuss the application fields, accuracy, usage methods and their roles of RoHS tester. LISUN RoHS is...
The scientific name of the dust sand test equipment is the sand and dust test chamber, which tests whether the product meets the IP protection level standard by simulating the free fall of dust without simulating an environment with wind speed. Dust sand test equipment is suitable for testing the sealing performance of the product’s shell, mainly used for testing the IP5X and IP6X levels sp...
Fluorescent materials are made of metal (zinc, chromium) sulfide or rare earth oxide and trace active agent by calcination. The color is generally colorless or light white. It is the visible light (400-800nm) of various colors under the irradiation of ultraviolet light (200-400nm), depending on the type and content of metal and activator in the pigment. Fluorescent materials absorb light of a cert...
Introduction There are two types of oscilloscopes, digital and analog, from which to choose for your electrical measuring requirements. There are benefits and drawbacks to using either kind of oscilloscope. To help you decide which sort of oscilloscope is best for you, this article will compare digital and analog models. You may pick the oscilloscope that is ideal for your needs by thinking about ...
Introduction Colorimetry and CRI measurements are very important in a wide variety of industries, including lighting, display technology, and the material sciences, amongst others. Integrating spheres have emerged as indispensable tools for accurate color assessment in recent years. These spheres provide a controlled environment for the illumination of samples and the collecting of reflected or tr...
The composite salt spray test chamber, also known as the programmable composite salt spray testing machine, breaks through the concept of traditional salt spray chambers. In addition to having the functions of regular salt spray testing machines, it also combines the functions of alternating (cyclic) salt spray testing, providing testing environments such as idiomorphic corrosion and filamentous ...
What is a integrating sphere: The integrating sphere is also known as a hollow sphere with a highly reflective inner surface. It is mainly a high-efficiency device that collects the scattering or emission of light by samples placed inside or outside the ball and close to a certain window, or the light emitted by the light source itself. It can be used to accurately measure the optical reflection ...
What is a Glow Wire Test? The glow wire test is to test the stability of electronic and electrical products when they are working. The glow wire itself is actually a resistance wire ring with a fixed specification. During glow wire test, it must be heated to a specified temperature with electricity, so that the top of the glow wire contacts the sample for a standard time, and then observe and meas...
Introduction: The reliability of electronic components and systems against ESD occurrences is largely determined by the results of ESD testing. During testing, electrostatic discharge (ESD) guns are often employed to simulate regulated ESD pulses. However, it might be difficult to establish which ESD gun type is the best match for your testing needs due to the market’s abundance of such prod...
