Autoclave or Pressure Cooker Test (PCT)
Autoclave Test, or Pressure Cooker Test (PCT), or Pressure Pot Test (PPOT), is a reliability test performed to assess the ability of a product to withstand severe temperature and humidity conditions.
It is used primarily to accelerate corrosion in the metal parts of the product, www.hast.cn including the metallization areas on the surface of the die. It also subjects the samples to the high vapor pressure generated inside the autoclave chamber. Figure 1 shows examples of autoclave chambers.
Fig. 1. Examples of Autoclave Chambers from Trio Tech
Autoclave testing consists of soaking the samples for 168 hours at 121 deg C, 100% RH, and 2 atm. Intermediate readpoints at 48H and 96H may also be employed.
Surface-mount samples are preconditioned prior to autoclave testing.www.hast.cn. Preconditioning simulates the board mounting process of the customer. It normally consists of a bake to drive away the moisture inside the packages of the samples, a soak to drive a controlled amount of moisture into the package, and three cycles of IR or vapor reflow.
The samples are tested after preconditioning, failures from which are considered as preconditioning failures and not autoclave failures. Preconditioning failures should be taken seriously, since these imply that the samples are not robust enough to even withstand the board mounting process.
Fig. 2. Another Example of an Autoclave Chamber
Because of the extreme moisture condition during autoclave testing, moisture-related electrical leakage failures may be encountered after the test. Unless predefined to be so, www.hast.cn such failures must not be considered as valid PCT failures. Only permanent failures, such as those arising from corrosion, are considered valid PCT failures.

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.
Daily maintenance tips for high and low temperature test chambers and alternating high and low temperature test chambers
1. High and low temperature test chambers are generally relatively high, and we recommend placing them in a relatively benign temperature environment. Our experience temperature value is 8 ℃~23 ℃. For laboratories that do not have this condition, appropriate air conditioners or cooling towers must be equipped.
2. It is necessary to adhere to professional management by dedicated personnel. Units with conditions should periodically send dedicated personnel to the supplier's factory for training and learning, in order to gain more professional experience and ability in maintenance and repair Hongzhan Instrument.
3. Regularly clean the condenser every 3 months: For compressors that use air-cooled cooling, the condenser fan should be regularly inspected and the condenser should be cleaned and dusted to ensure good ventilation and heat transfer performance; For compressors that use water-cooled cooling, in addition to ensuring their inlet water pressure and temperature, it is also necessary to ensure the corresponding flow rate. Regular cleaning and descaling of the condenser interior is also necessary to obtain its continuous heat transfer performance.
4. Regularly clean the evaporator: Due to the different cleanliness levels of the test samples, a lot of small particles such as dust will accumulate on the evaporator under forced air circulation, and should be cleaned regularly.
5. Cleaning and balancing of circulating air blades and condenser fans: Similar to cleaning evaporators, due to the different working environments of the test chamber, many small particles such as dust may accumulate on the circulating air blades and condenser fans, and should be cleaned regularly.
6. Cleaning of waterway and humidifier: If the waterway is not smooth and the humidifier scales, it is easy for the humidifier to dry and burn, which may damage the humidifier. Therefore, it is necessary to regularly clean the waterway and humidifier.
7. After each experiment, set the temperature near the ambient temperature, work for about 30 minutes, then cut off the power and clean the inner wall of the workshop.
If the equipment needs to be relocated, it is best to do so under the guidance of technical personnel from Hongzhan Company to avoid unnecessary damage or damage to the equipment.
When the product is not in use for a long period of time, it should be powered on regularly every half month, and the power on time should not be less than 1 hour.
10. Maintenance principle:
Due to the fact that high and low temperature test chambers are mainly composed of electrical, refrigeration, and mechanical systems, once there is a problem with the equipment, a comprehensive inspection and analysis of the entire equipment system should be carried out.
Generally speaking, the process of analysis and judgment can start with "external" and then "internal", that is, after excluding external factors, the equipment can be systematically decomposed based on the fault phenomenon. Then, the system can be comprehensively analyzed and judged. Alternatively, the reverse reasoning method can be used to find the cause of the fault: first, check whether there is a problem with the electrical system according to the electrical wiring diagram, and finally check whether there is a problem with the refrigeration system. Before understanding the cause of the fault, it is not advisable to disassemble or replace components blindly to avoid unnecessary trouble.
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)
