Temperature Cycling Test

Temperature Cycling, in order to simulate the temperature conditions encountered by different electronic components in the actual use environment, changing the ambient temperature difference range and rapid rise and fall temperature change can provide a more stringent test environment, but it must be noted that additional effects may be caused to material testing. For the relevant international standard test conditions of temperature cycle test, there are two ways to set the temperature change. Macroshow Technology provides an intuitive setting interface, which is convenient for users to set according to the specification. You can choose the total Ramp time or set the rise and cooling rate with the temperature change rate per minute.

List of international specifications for temperature cycling tests:

Total Ramp time (min) : JESD22-A104, MIL-STD-8831, CR200315

Temperature variation per minute (℃/min) : IEC 60749, IPC-9701, Bellcore-GR-468, MIL-2164

Example: Lead-free solder joint reliability test

Instructions: For the reliability test of lead-free solder joints, different test conditions will also be different in terms of the temperature change setting mode. For example, (JEDEC JESD22-A104) will specify the temperature change time with the total time [10min], while other conditions will specify the temperature change rate with [10℃/ min], such as from 100 ℃ to 0℃. With a temperature change of 10 degrees per minute, that is to say, the total temperature change time is 10 minutes.

The first natural environment icing test station in China, jointly built by Chongqing University and Huaihua Electric Power Bureau, has settled in Xuefeng Mountain!

On January 16th, the "Xuefengshan Natural Ice Cover Test Station" Insulator Ice Cover Test Technology Exchange Seminar, jointly organized by Chongqing University and Hunan Huaihua Electric Power Design Institute, was held in Huaihua. Experts in transmission and distribution lines and insulation technology from well-known universities across the country, as well as electrical experts from Japan's NGK company, gathered together to celebrate the official completion of the world's only and China's first natural ice cover test station in Huaihua, Hunan, and to discuss follow-up research matters.

At the meeting, Professor Jiang Xingliang, doctoral supervisor of Chongqing University, first expressed gratitude to Huaihua Electric Power Bureau and various units of the power system for their strong support and assistance in the basic design and construction of the experimental base. The attending experts listened to Associate Professor Zhang Zhijin's report on the construction of the Xuefengshan Natural Ice Cover Test Station and the 2009 Ice Cover Test, shared the ice observation and research results at the test base throughout 2009, and conducted in-depth discussions and research on the existing problems. After the meeting, experts also went to the "Xuefengshan Natural Ice Cover Test Station" for on-site investigation, and representatives expressed their affirmation of the site selection and the construction of the test station.

Professor Jiang Xingliang introduced that since the 2008 ice disaster, in order to prevent a large number of line disconnections, tower collapses, and ice flash accidents caused by severe icing, and to maintain the safe and stable operation of the power grid, the Ministry of Science and Technology of China has listed grid icing and protection technology as one of the important research topics of the National Key Basic Research and Development Plan (973 Plan). With the support of projects such as "Ice Cover, De icing, and Melting Mechanisms of Transmission Lines" by State Grid Corporation of China, Professor Jiang Xingliang's research team conducted a comprehensive investigation of typical ice cover conditions in China, analyzed and compared ice cover phenomena and micro meteorology in Liupanshui, Guizhou, Qinling Mountains, Shaanxi, Jingmen, Sichuan, and Lushan, Jiangxi. Based on the representativeness, duration, and transportation conditions of ice cover, it was determined to establish a "natural ice cover test base" in Xuefengshan, Hunan. It was believed that the natural conditions of Pingshantang in Xuefengshan and the technical strength of Huaihua Design Institute met the requirements for the construction of natural ice cover test bases. Finally, the site selection and cooperation partner were determined.

In 2009, Professor Jiang Xingliang, Associate Professor Zhang Zhijin, and Dr. Hu Jianlin, among other key members of the research group, led more than ten graduate students from the Department of High Voltage and Insulation Technology at Chongqing University to overcome various difficulties in work and life under harsh natural conditions. They worked together with the Huaihua Bureau Design Institute to build a natural experimental base while conducting experimental research. In the first year of the experiment, the icing, thawing, and de icing processes of six typical specifications of conductors commonly used in high voltage, ultra-high voltage, and ultra-high voltage transmission lines were studied. The icing processes of various types of insulators were observed and compared. Multiple technical measures to prevent conductor icing, such as mechanical and hydrophobic coatings, as well as coatings to prevent insulator icing and differences in insulator icing arrangements, were experimentally investigated. The twisting process and mechanism of conductor icing were analyzed, and the tension changes and ice wind load changes after conductor icing were analyzed. In addition, AC and DC icing tests were conducted in natural environments. A large amount of key experimental data was accumulated to overcome the world-class problem of power grid icing, and many effective studies and explorations were made.

Toshiyuki Nakajima, Chief Engineer of the Electric Power Division of NGK Corporation in Japan, stated in an interview with reporters during his inspection of the Xuefengshan Natural Ice Cover Test Station that he has been engaged in research on power grid ice cover in the United States for 10 years. Although international experts have conducted long-term research on power grid ice cover under laboratory artificial simulation conditions, they unanimously believe that there is a significant error between the ice cover form in the artificial simulation environment and the actual situation in the natural environment. The first natural ice cover test station built in Xuefengshan will undoubtedly greatly promote the research process of ice cover and melting mechanisms of transmission lines and the anti ice ability of power grids in China and internationally. He wishes his Chinese counterparts to soon obtain the foundation of ice cover on transmission lines in natural environments. Data fills the gap in international research in this field, Overcome the world-class challenge of power grid icing mechanism and anti icing technology as soon as possible.

Zhang Jiwu, President of the Design Institute of Huaihua Electric Power Bureau, stated that with the strong support of Secretary Liang Liqing of the Huaihua Electric Power Bureau Party Committee, the Xuefengshan Natural Ice Cover Test Station has been built in cooperation with Chongqing University. On the one hand, it can make its own contribution to the research on improving the ice resistance of the power grid and reflect the company's sense of social responsibility; On the other hand, it can also enhance its own technological strength and corporate reputation through cooperation and exchange, improve its external competitiveness, and achieve a win-win situation. It is a model of "industry university research" cooperation between enterprises and higher education institutions. (Shu Daisong and Zhang Deming)

VMR- plate Temperature Cycle Transient Break Test

Temperature cycle test is one of the most commonly used methods for reliability and life test of lead-free welding materials and SMD parts. It evaluates the adhesive parts and solder joints on the surface of SMD, and causes plastic deformation and mechanical fatigue of solder joints materials under the fatigue effect of cold and hot temperature cycle with controlled temperature variability, so as to understand the potential hazards and failure factors of solder joints and SMD. The Daisy chain diagram is connected between the parts and the solder joints. The test process detects the on-off and on-off between the lines, parts and solder joints through the high-speed instantaneous break measuring system, which meets the demand for the reliability test of electrical connections to evaluate whether the solder joints, tin balls and parts fail. This test is not really simulated. Its purpose is to apply severe stress and accelerate the aging factor on the object to be tested to confirm whether the product is designed or manufactured correctly, and then evaluate the thermal fatigue life of the component solder joints. The reliability test of the electrical high-speed instantaneous break connection has become a key link to ensure the normal operation of the electronic system and avoid the failure of the electrical connection caused by the failure of the immature system. The resistance changes over a short period of time were observed under accelerated temperature changes and vibration tests.

Purpose:

1. Ensure that products designed, manufactured and assembled meet predetermined requirements

2. Relaxation of solder joint creep stress and SMD fracture failure caused by thermal expansion difference

3. The maximum test temperature of the temperature cycle should be 25℃ lower than the Tg temperature of the PCB material, so as to avoid more than one damage mechanism of the substitute test product

4. Temperature variability at 20℃/min is a temperature cycle, and temperature variability above 20℃/min is a temperature shock

5. The welding joint dynamic measurement interval does not exceed 1min

6. The high temperature and low temperature residence time for failure determination needs to be measured in 5 strokes

Requirements:

1. The total temperature time of the test product is within the range of the rated maximum temperature and the minimum temperature, and the length of the residence time is very important for the accelerated test, because the residence time is not enough during the accelerated test, which will make the creep process incomplete

2. The resident temperature must be higher than Tmax temperature and lower than Tmin temperature

Refer to the list of specifications:

IPC-9701, IPC650-2.6.26, IPC-SM-785, IPCD-279, J-STD-001, J-STD-002, J-STD-003, JESD22-A104, JESD22-B111, JESD22-B113, JESD22-B117 , SJR-01

The working principle of the trough-type electromagnetic vibrating feeder is to utilize the periodic vibration generated by the electromagnetic vibrator to make the materials in the material trough be subjected to an inertial force perpendicular to the direction of gravity. When the inertial force on the material is greater than the friction force between the material and the material trough, the material will move forward in the material trough, thus achieving the purpose of feeding. During the vibration process, the material presents a jumping micro-throwing movement. This movement mode enables the material to be evenly distributed in the material trough and be transported forward at a stable speed.

• Adjustable feeding amount: By changing the working parameters of the electromagnetic vibrator, stepless adjustment of the feeding amount can be easily realized to meet the requirements of different production processes.

• Simple structure: It is mainly composed of parts such as material trough, electromagnetic vibrator, vibration damping device and adjusting device. It has a compact structure, small volume, light weight, and is convenient for installation and maintenance.

• Reliable operation: There are no rotating parts, and there are no mechanical wear and lubrication problems, reducing the failure rate of the equipment and improving the service life of the equipment. At the same time, the working stability of the electromagnetic vibrator is high and it can operate stably for a long time in harsh working environments.

• Low energy consumption: Due to the adoption of the electromagnetic vibration principle, the equipment consumes less electric energy during operation and has a good energy-saving effect.

• Low noise: The noise generated during the operation of the equipment is small, which has little impact on the surrounding environment and improves the environmental conditions of the workplace.

• Metallurgical industry: In the metallurgical production process, trough-type electromagnetic vibrating feeders can be used to transport raw materials such as iron ore, coke, and limestone to equipment such as ironmaking blast furnaces, steelmaking converters, and sintering machines to ensure the smooth progress of metallurgical production.

• Coal industry: It can be used for the transportation and feeding of coal, and uniformly transport coal from coal bins to equipment such as belt conveyors, jigging machines, and flotation machines, improving the washing efficiency and quality of coal.

• Chemical industry: In chemical production, trough-type electromagnetic vibrating feeders can be used to transport various powdery and granular chemical raw materials, such as plastic particles, fertilizers, soda ash, and salt, ensuring the continuity and stability of the chemical production process.

• Building materials industry: Widely used in building materials industries such as cement, glass, and ceramics, it is used to transport raw materials such as limestone, gypsum, quartz sand, and clay, providing a stable material supply for building materials production.

• Food industry: In the food processing process, it can be used to transport food raw materials such as rice, wheat, beans, and candies. It has the advantages of hygiene, no pollution, and uniform feeding, and can meet the production requirements of the food industry.

Electromagnetic vibrating feeder is the good solution of powder conveying/feeding and granular handling/feeding. How do we purchase a high quality electromagnetic vibrating feeder? VRV, the professional vibrating feeder supplier will tell you ways：

• Material characteristics: including the particle size, humidity, viscosity, density, etc. of the material. Different material characteristics have a great influence on the selection of feeders. For example, for materials with larger particle size, higher humidity, and stronger viscosity, a larger model feeder with stronger vibration ability and anti-blocking function should be selected.

• Feeding amount requirements: According to the needs of the production process, determine the required feeding amount range. When selecting a model, a feeder whose feeding amount can meet the production requirements should be selected, and a certain margin should be left to adapt to changes in the production process.

• Installation method: There are two installation methods for trough-type electromagnetic vibratory feeders: seated installation and suspended installation. Seated installation is suitable for occasions with good ground foundation and large space; suspended installation is suitable for occasions with limited space and the need to save floor space. When selecting a model, an appropriate installation method should be selected according to the actual installation conditions on site.

• Working environment: Consider the working environment of the feeder, such as temperature, humidity, dust concentration, etc. If the working environment is harsh, a feeder with higher protection level, corrosion resistance, wear resistance and other properties should be selected to ensure the normal operation and service life of the equipment.

Please be informed that the electromagnetic vibrator is the core component of the electromagnetic feeder. You should not buy an electromagnetic vibration feeder mainly because of its low price. You should seek professional manufacturers and material handling experts for electromagnetic vibration feeders.

<span style=”font-size:16px;font-family:” times=”” new=”” roman”;”=””>In the realm of industrial automation, electromagnetic vibrators play a crucial role in facilitating smooth and optimized material handling processes. A key component of the electromagnetic vibrating feeder, the magnetic vibrator, drives the feeder’s operation with precision and reliability. This article will delve into the benefits of VRV’s magnetic vibrator and highlight its advantages, along with VRV’s exceptional service offerings.

Vibrating feeder is a kind of equipment used to uniformly and quantitatively feed bulk and granular materials from the silo or storage hopper to the receiving device. It plays a huge role in material handling.

I. In terms of uniform feeding

1. Precise control of flow: The vibrating feeder can precisely control the flow of materials by adjusting parameters such as vibration frequency and amplitude. For example, in the ore processing industry, when ore needs to be transported from the silo to the crusher, the vibrating feeder can supply ore uniformly at a set speed. This can ensure that the crusher operates in a relatively stable working state, avoiding clogging of the crusher due to excessive materials or idling of the equipment due to insufficient materials, reducing the production efficiency of the equipment.

2. Ensure stable quality of subsequent processes: In chemical production, for some process processes that require precise batching, the vibrating feeder can ensure that various raw materials are uniformly supplied to equipment such as reactors in appropriate proportions. Taking the production of a certain compound fertilizer as an example, nitrogen fertilizer, phosphate fertilizer, potassium fertilizer and other multiple raw materials need to be uniformly mixed. The vibrating feeder can make each raw material stably enter the mixing equipment to ensure the accurate proportion of the components of the compound fertilizer, thereby ensuring the stability of product quality.

II. In terms of material transportation

1. Realize efficient transportation: The vibrating feeder can transport materials from one location to another, especially for some materials with poor fluidity such as granular and blocky materials. It uses the power generated by vibration to make the materials have a forward movement trend on the trough body. For example, in the construction industry, it is used to transport building materials such as sand and gravel. If these materials rely on natural flow, it will be relatively slow, and the vibrating feeder can quickly transport them to equipment such as mixers, improving the work efficiency of the entire building material processing.

2. Adapt to various material characteristics: It can handle materials with various different characteristics, including wet and sticky materials. For example, in ceramic production, sometimes the raw materials are somewhat sticky, and the vibrating feeder can still effectively transport them. Because vibration can break the sticky connection between materials and make the materials move smoothly on the trough body.

III. In terms of preliminary treatment of material screening

Simple screening function: The vibrating feeder can also perform preliminary screening of materials during the feeding process. Its vibration effect can make smaller particles pass through the screen on the trough body, while larger particles continue to move forward on the trough body. In the coal processing industry, after coal is mined from the mine, it contains particles of various sizes. The vibrating feeder can screen out finer particles such as pulverized coal. Coarse-grained coal is then continuously transported to subsequent washing or crushing processes. In this way, a part of qualified products can be separated in advance, and it is also conducive to the further processing of coarse-grained coal in the future.

According to different driving methods, we can divide vibrating feeders into motor vibrating feeders and electromagnetic vibrating feeders. They have their own advantages. The motor vibrating feeder has a large conveying capacity and is relatively inexpensive. The electromagnetic vibrating feeder handles materials gently and is convenient for speed adjustment, but the price is relatively high.

VRV is an expert in manufacturing vibrating feeders. We can customize feeders according to customer needs. According to the advantages of motor feeders and electromagnetic feeders, we can combine the two. Make this feeding system an important link in the material handling production line.

I. Advantages of electromagnetic vibrator

1. High efficiency: The electromagnetic vibrator can generate high-frequency and high-amplitude vibrations, thereby quickly and effectively transporting materials.

2. Precision: The electromagnetic vibrator can precisely control the amplitude and frequency of vibration by adjusting the current and voltage, so as to meet the transportation needs of different materials. This precision can ensure that the materials will not be damaged during transportation, and at the same time can improve the quality and stability of production.

3. Reliability:

The structure of the electromagnetic vibrator is simple and there are no mechanical transmission parts, so the failure rate is low and the reliability is high. The electromagnetic vibrator has a long service life and can operate stably for a long time in harsh environments. For example, in some industries such as mining and metallurgy, electromagnetic vibrators can work in harsh environments such as high temperature, high humidity and high dust, providing reliable guarantee for enterprise production.
