Abstract Mechanical impact testing is a critical part of assessing the durability and robustness of various products. This paper explores the application of the spring tester in the context of the LISUN IK01-06 Spring Impact Hammer, which is designed according to the IEC 60068-2-75 standard. The purpose of the test is to simulate mechanical shocks that a product may experience during normal use. T...
Introduction Capacitors are fundamental components in modern electronic systems, offering critical functions such as energy storage, signal filtering, and power management. Accurate measurement of capacitance, particularly in large-capacitance capacitors, is essential for ensuring optimal performance in applications ranging from power electronics to telecommunications. The LISUN LS6515EN Capacitor...
Introduction The IP65 test is a critical procedure for determining the effectiveness of enclosures in protecting internal components from environmental factors such as dust and water. The “IP” in IP65 stands for “Ingress Protection,” while the digits refer to the level of protection the enclosure provides. Specifically, “6” denotes full protection against dust, ...
Introduction The UL flammability rating is a critical standard that classifies materials based on their ability to withstand flame exposure. This rating system is essential for ensuring the safety and reliability of products, especially in industries like electronics, lighting, and household appliances. The UL 94 test method, which includes both horizontal and vertical flammability testing, is wid...
Abstract The hipot test, short for “high potential” test, is crucial for assessing the dielectric strength of electrical components, especially capacitors. It verifies that these components can withstand high voltages without breaking down or leaking excessive current. The key parameter in this test is the hipot test acceptable leakage current, which defines the limit of current that c...
Abstract Electrostatic discharge (ESD) is a critical concern in semiconductor device manufacturing and testing, as it can cause significant damage to integrated circuits (ICs). Among the various ESD models used for testing, the Human Body Model (HBM) is the most prevalent for simulating electrostatic discharges that mimic human contact with sensitive devices. This paper explores the ESD HBM model ...
Introduction In industries where precise color measurements are crucial, such as printing, textiles, plastics, and paint manufacturing, the need for accurate and portable color measuring devices has never been more essential. The pocket colorimeter has become an indispensable tool, offering convenience and precision for quick, on-site color evaluations. One such device is the LISUN CD-320PRO Porta...
Introduction The dustproof rating test is an essential aspect of evaluating electronic devices, enclosures, and other industrial equipment that are exposed to harsh environments. Understanding how effectively a product can withstand dust intrusion is crucial for determining its long-term durability and performance. The dust measuring instrument plays a critical role in accurately assessing the dus...
Introduction When testing the luminous flux and other photometric properties of LED lighting, integrating spheres are essential tools for accurate measurements. These measurements, often referred to in terms of the light meter lumen, provide critical data for quality control and product development. A common debate in the photometry field is whether one-piece (seamless) integrating spheres offer b...
