In addition to the selection and circuit design of components, good printing circuit board (PCB) design is also a very important factor in electromagnetic compatibility. The key to the design of PCB in EMC is to reduce the return area as much as possible and let the return path flow in the direction of the design. The most common return current comes from the cracks of the reference plane, the tra...
LPCE-2 Integrating Sphere Spectroradiometer LED Testing System is for single LEDs and LED lighting products light measurement. LED’s quality should be tested by checking its photometric, colorimetric and electrical parameters. According to CIE 177, CIE84, CIE-13.3, IES LM-79-19, Optical-Engineering-49-3-033602, COMMISSION DELEGATED REGULATION (EU) 2019/2015, IESNA LM-63-2, IES-LM-80 ...
Due to the strong oxidizing effect of ozone, it can accelerate the aging of rubber and metals; Therefore, what the rubber industry absolutely cannot lack is an ozone aging test chamber, which simulates and strengthens the ozone conditions in the atmosphere, and is used to test the ozone aging resistance test performance of products. It can be divided into static and dynamic types according to cust...
In industrial production, when testing electronic components, it is necessary to use a High and Low Temperature Thermal Shock Chamber for testing. It is used for temperature cold and hot impact testing. The time of temperature conversion is short and the change is fast, so it can impact the temperature of product testing. Detect chemical changes or physical damage caused by thermal expansion and c...
The IPX56 waterproof test chamber is a testing equipment used to evaluate the sealing and waterproofing performance of products. It can be used to test products for IPX5 or IPx6 waterproof levels, and its application range is also relatively wide, such as in various electronic and electrical industries and products such as automobiles, LED lighting fixtures, diving, and other fields. The waterproo...
The sand dust chamber is a device that uses artificial simulation systems to simulate the impact of natural dust environment, wind and sand, and to test various electronic devices. Before use, calibration is necessary to ensure the accuracy and credibility of the test results. The sand dust chamber generally has two protection levels and can be used for testing various electronic and electrical pr...
The optical system is the core part of the spectrophotometer. Based on the basic principles of the spectrometer and optical design theory, with the specific design goal of portability, low cost, and meeting the design requirements of the spectral range and resolution, four feasible design schemes, namely the Littrow system, the Albert Fastian system, the Cherney Turner system, and the crossed Cher...
The Glossmeter is an instrument used to measure the surface glossiness of materials such as ceramics, paint, ink, plastic, marble, aluminum, and hardware. The Glossmeters with single angle or with three angles. Firstly, glossiness is a physical quantity that evaluates the ability of a material’s surface to reflect light under a set of geometric specified conditions, with directional reflecti...
The scientific name of sand and dust test chamber is dustproof test chamber, which is implemented according to international national standard parameters such as GB4208-2017 Enclosure Protection Class (IP Code). It is used to test the physical and other related properties of the product by simulating the climatic conditions of natural dust. After the test, the performance of the product can be jud...
