Polarizer Test Conditions

Polarizer is one of the basic parts of the liquid crystal display, is a light plate that only allows a certain direction of light to pass through, in the process of making the liquid crystal plate, must be used above and below each piece, and into the staggered direction placed, mainly used for electric field and no electric field when the light source produces a phase difference and the state of light and dark, to display subtitles or patterns.

Relevant test conditions:

Because the molecular structure of iodine is easy to destroy under high temperature and humidity conditions, the durability of the polarizer produced by iodine dyeing technology is poor, and generally can only meet:

High temperature: 80℃×500HR

Hot and humid: working conditions below 60℃×90%RH×500HR

However, with the expansion of the use of LCD products, the wet and hot working conditions of polarizing products are becoming more and more demanding, and there has been a demand for polarizing plate products that work at 100 ° C and 90%RH conditions, and the highest conditions at present are:

High temperature: 105℃×500HR

Humidity and heat: test requirements below 90℃×95%RH×500HR

The durability test of polarizer includes four test methods: high temperature, wet heat, low temperature and cold and heat shock, of which the most important test is the wet and heat test. The high temperature test refers to the high temperature working conditions of the polarizer at a constant baking temperature. At present, according to the technical grade of the polarizer, it is divided into:

Universal type: working temperature is 70℃×500HR;

Medium durability type: the working temperature is 80℃×500HR;

High durability type: the operating temperature is 90℃×500H above these three grades.

Because the basic materials of the polarizing film PVA film and iodine and iodide are easily hydrolyzed materials, but also because the pressure sensitive adhesive used in the polarizing plate is also easy to deteriorate under high temperature and high humidity conditions, the most important things in the environmental test of the polarizing plate are high temperature and wet heat.

Purpose of Temperature Shock Test

Reliability environmental test In addition to high Temperature, low temperature, high temperature and high humidity, temperature and humidity combined cycle, temperature Shock (cold and hot Shock) is also a common test project, temperature shock Testing (Thermal Shock Testing, Temperature Shock Testing, referred to as: TST), the purpose of the temperature shock test is to find out the design and process defects of the product through the severe temperature changes that exceed the natural environment [temperature variability greater than 20℃/min, and even up to 30 ~ 40℃/min], but there is often a situation where the temperature cycle is confused with the temperature shock. "Temperature cycle" means that in the process of high and low temperature change, the temperature change rate is specified and controlled; The temperature change rate of "temperature shock" (hot and cold shock) is not specified (Ramp Time), mainly requires Recovery Time, according to the IEC specification, there are three kinds of temperature cycle test methods [Na, Nb, NC]. Thermal shock is one of the three [Na] test items [rapid temperature change with specified conversion time; medium: air], the main parameters of temperature shock (thermal shock) are: High temperature and low temperature conditions, residence time, return time, number of cycles, in high and low temperature conditions and residence time the current new specification will be based on the surface temperature of the test product, rather than the air temperature in the test area of the test equipment.

Thermal shock test chamber:

It is used to test the material structure or composite material, in an instant under the continuous environment of extremely high temperature and extremely low temperature, the degree of tolerance, so as to test the chemical changes or physical damage caused by thermal expansion and contraction in the shortest time, the applicable objects include metal, plastic, rubber, electronic.... Such materials can be used as the basis or reference for the improvement of its products.

The cold and thermal shock (temperature shock) test process can identify the following product defects:

Different expansion coefficient caused by the stripping of the joint

Water enters after cracking with different expansion coefficient

Accelerated test for corrosion and short circuit caused by water infiltration

According to the international standard IEC, the following conditions are common temperature changes:

1. When the equipment is transferred from a warm indoor environment to a cold outdoor environment, or vice versa

2. When the equipment is suddenly cooled by rain or cold water

3. Installed in the outside airborne equipment (such as: automobile, 5G, outdoor monitoring system, solar energy)

4. Under certain transport [car, ship, air] and storage conditions [non-air-conditioned warehouse]

Temperature impact can be divided into two types of two-box impact and three-box impact:

Instructions: Temperature impact is common [high temperature → low temperature, low temperature → high temperature] way, this way is also called [two-box impact], another so-called [three-box impact], the process is [high temperature → normal temperature → low temperature, low temperature → normal temperature → high temperature], inserted between the high temperature and low temperature, to avoid adding a buffer between the two extreme temperatures. If you look at the specifications and test conditions, there is usually a normal temperature condition, the high and low temperature will be extremely high and very low, in the military specifications and vehicle regulations will see that there is a normal temperature impact condition.

IEC temperature shock test conditions:

High temperature: 30, 40, 55, 70, 85, 100, 125, 155℃

Low temperature: 5, -5, -10, -25, -40, -55, -65℃

Residence time: 10min, 30min, 1hr, 2hr, 3hr(if not specified, 3hr)

Temperature shock residence time description:

The Dwell Time of temperature shock in addition to the requirements of the specification, some will depend on the weight of the test product and the surface temperature of the test product

The specifications of the thermal shock residence time according to weight are:

GJB360A-96-107, MIL-202F-107, EIAJ ED4701/100, JASO-D001... Let's wait.

The thermal shock residence time is based on the surface temperature control specifications: MIL-STD-883K, MIL-STD-202H(air above the test object)

MIL883K-2016 requirements for [temperature shock] specification:

1. After the air temperature reaches the set value, the surface of the test product needs to arrive within 16 minutes (residence time is not less than 10min).

2. High temperature and low temperature impact are more than the set value, but not more than 10℃.

Follow-up action of IEC temperature shock test

Reason: The IEC temperature test method is best considered as part of a series of tests, because some failures may not be immediately apparent after the test method is completed.

Follow-up test items:

IEC60068-2-17 Tightness test

IEC60068-2-6 Sinusoidal vibration

IEC60068-2-78 Steady Humid heat

IEC60068-2-30 Hot and humid temperature cycle

Tin whisker (whisker) temperature impact test conditions finishing:

4. - 55 (+ 0 / -) 10 ℃ please - 80 (+ / - 0) 10 ℃, 7 min reside, 20 min / 1 cycle, 1000 cycles

Thermal shock testing machine product features:

Defrosting frequency: defrosting every 600cycles [Test condition: +150℃ ~ -55℃]

Load adjustment function: The system can automatically adjust according to the load of the product to be tested, without manual setting

High weight load: Before the equipment leaves the factory, use aluminum IC(7.5Kg) for load simulation to confirm that the equipment can meet the demand

Temperature shock Sensor location: The air outlet and return air outlet in the test area can be selected or both can be installed, which conforms to the MIL-STD test specification. In addition to meeting the requirements of the specification, it is also closer to the impact effect of the test product during the test, reducing the test uncertainty and distribution uniformity.

Reliability Environmental Test Equipment Combined with Multi-track Temperature Control and Detection Applications

Environmental test equipment includes constant temperature and humidity test chamber, hot and cold shock test chamber, temperature cycle test chamber, no wind oven... These test equipment are all in the simulated environment of temperature, humidity impact on the product, to find out the design, production, storage, transportation, use process may appear product defects, previously only simulated test area air temperature, but in the new international standards and the new test conditions of the international factory, the beginning of the requirements based on the air temperature is not. It is the surface temperature of the test product. In addition, the surface temperature should also be measured and recorded synchronously during the test process for post-test analysis. The relevant environmental test equipment should be combined with surface temperature control and the application of surface temperature measurement is summarized as follows.

Constant temperature and humidity test chamber test table temperature detection application:

Description: Constant temperature and humidity test chamber in the test process, combined with multi-track temperature detection, high temperature and humidity, condensation (condensation), combined temperature and humidity, slow temperature cycle... During the test process, the sensor is affixed to the surface of the test product, which can be used to measure the surface temperature or internal temperature of the test product. Through this multi-track temperature detection module, the set conditions, actual temperature and humidity, the surface temperature of the test product, and the same measurement and record can be integrated into a synchronous curve file for subsequent storage and analysis.

Thermal shock test chamber surface temperature control and detection applications: [dwell time based on surface temperature control], [temperature shock process surface temperature measurement record]

Description: The 8-rail temperature sensor is attached to the surface of the test product and applied to the temperature shock process. The dwell time can be counted backward according to the arrival of the surface temperature. During the impact process, the setting conditions, the test temperature, the surface temperature of the test product, and the same measurement and record can be integrated into a synchronous curve.

Temperature cycle test chamber surface temperature control and detection application: [Temperature cycle temperature variability and dwell time are controlled according to the test product surface temperature]

Description: Temperature cycle test is different from temperature shock test. Temperature shock test uses the maximum energy of the system to carry out temperature changes between high and low temperatures, and its temperature change rate is as high as 30 ~ 40℃ /min. Temperature cycle test requires a process of high and low temperature changes, and its temperature variability can be set and controlled. However, the new specification and the test conditions of international manufacturers have begun to require that the temperature variability refers to the surface temperature of the test product, not the air temperature, and the current temperature cycle specification temperature variability control. According to the test product surface specifications are [JEDEC-22A-104F, IEC60749-25, IPC9701, ISO16750, AEC-Q100, LV124, GMW3172]... In addition, the residence time of high and low temperatures can also be based on the test surface, rather than the air temperature.

Temperature cyclic stress screening test chamber surface temperature control and detection applications:

Instructions: Temperature cycle stress screening testing machine, combined with multi-rail temperature measurement, in the temperature variability of stress screening, you can choose to use [air temperature] or [test product surface temperature] to control the temperature variability, in addition, in the high and low temperature resident process, the time reciprocal can also be controlled according to the surface of the test product. In accordance with the relevant specifications (GJB1032, IEST) and the requirements of international organizations, according to the definition of GJB1032 in the stress screening residence time and temperature measurement point, 1. The number of thermocouples fixed on the product shall not be less than 3, and the temperature measurement point of the cooling system shall not be less than 6, 2. Ensure that the temperature of 2/3 thermocouples on the product is set at ±10℃, in addition, according to the requirements of IEST(International Association for Environmental Science and Technology), the residence time should reach the temperature stabilization time plus 5min or performance test time.

No air oven (natural convection test chamber) surface temperature detection application:

Description: Through the combination of a windless oven (natural convection test chamber) and a multi-track temperature detection module, the temperature environment without fan (natural convection) is generated, and the relevant temperature detection test is integrated. This solution can be applied to the actual ambient temperature test of electronic products (such as: Cloud server, 5G, electric vehicle interior, indoor without air conditioning environment, solar inverter, large LCD TV, home Internet sharer, office 3C, laptop, desktop, game console....... Etc.).

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
