Rapid temperature change test chamber: Suitable for aerospace, information electronics, instrumentation, materials, electrical, electronic products, and various vital parts to judge whether parameters such as reliability, machine stability, and performance are qualified in high and low temperature or humid heat environments, and will be provided to The basis for you to predict and improve product quality and reliability. The rapid temperature change test chamber is divided into three parts: high temperature area, low temperature area and test area. It adopts the original Japanese Youyi control brand temperature instrument, Chinese and English display control system; it has a fully automatic and high-precision system. Any part of the movement is completely controlled by P.L.C. Locking processing; automatic circuit and warning signal when the parts fail; emergency stop device when the input voltage is unstable. The heating and cooling humidification system of the test chamber is independ...

Abstract With the widespread application of electronic equipment, electromagnetic compatibility (EMC) has become a key indicator in product design and production. This paper takes the LISUN EMI-9KB EMI Receiver Test System as the research object, and analyzes in detail its technical characteristics, testing capabilities and application scenarios. The system adopts a fully enclosed structure and highly conductive materials, achieving excellent shielding effect and fundamentally solving the problem of the equipment’s own interference. Through test procedures and report formats that comply with international standards, the EMI-9KB can meet the requirements of multiple specifications such as CISPR, GB, and FCC, providing reliable support for EMC certification of electronic equipment. Actual test data shows that the measurement accuracy of the system in the 30MHz-1GHz frequency band can reach ±1.5dB, and the repeated test deviation is less than 0.8dB, demonstrating excellent stability and a...

In-depth Analysis of Pressure Testing Methods and Standardization Guidelines Operation Steps and Methods of Ball Pressure Testing: 1. Sample Pressure Treatment: Place the sample under the pressure device and subject it to one hour of pressure, ensuring testing in an abnormally high-temperature environment. This step aims to simulate the behavior of the sample under specific environmental conditions. 2. Heating Stage: Place the sample in a preheating oven, ensuring that the internal temperature stabilizes at 125°C±2°C. After one hour of constant temperature treatment, remove the sphere applied on the sample to facilitate subsequent observations. 3. Cooling Treatment: Quickly immerse the heated sample into cold water, with a cooling time of approximately 10 seconds, to rapidly reduce the temperature to room temperature. This aids in observing the sample’s reaction to temperature changes. 4. Observation of Phenomena: Throughout the entire process, closely observe any changes, deformations...
