  Semiconductor chip high and low temperature test is a necessary test equipment for metal, components, electronics and other material industries. It is used to test the degree of material structure or composite material that can be endured in a continuous environment of high temperature and low temperature in a short time. The chemical change or physical damage caused by thermal expansion and contraction of the internal test sample.
  The high and low temperature test of semiconductor chips has simple and convenient operation performance and reliable equipment performance. Physical changes in defense industry, aerospace, BGA, PCB base, electronic chip IC, semiconductor ceramics and polymer materials.

  

  Special attention should be paid to the high and low temperature test of semiconductor chips. The high and low temperature test of semiconductor chips cannot be easily opened during use. The main reasons are as follows:

  The semiconductor chip high and low temperature test is a test box that simulates the environment. During use, there may be various extreme environments in the test box, such as low temperature, high temperature and high pressure, high temperature and high humidity and other special conditions.

  If a low temperature test of -70°C is being performed in the test box, open the door of the test box at this time, and the cold air flow will overflow the test box. If our fingers touch the samples on the wall of the test box without any protection, they will be frozen instantly. , the muscle tissue at the frostbitten site may even necrosis. In addition, opening the door of the test chamber at a lower temperature may cause frost on the evaporator, which will affect the cooling speed, and may even cause problems such as damage to the compressor.

  If the door of the test chamber is opened during a test at a high temperature of 150°C in the test chamber, the high-temperature gas will burst out of the test chamber in an instant. Combustibles may even cause a fire.

  If it is other environmental test equipment, such as the constant temperature and humidity test chamber in the high temperature and high humidity test chamber, the pressure and steam in the instrument will be very large. If the door of the test chamber is opened at this time, there will also be high temperature and high humidity steam. Running out of the test chamber is also more likely to cause serious burns to the operator.

  Therefore, in the middle of the high and low temperature test of the semiconductor chip, if it is not necessary to open the door of the test box, do not open the door of the test line. Open the test chamber door.

  The accurate selection of the semiconductor test chiller needs to meet 6 conditions. When we need to buy a semiconductor test chiller, choosing a large one will waste material resources, and choosing a small one will not achieve the cooling effect, so how can we accurately select the semiconductor test chiller machine?

  The demand for semiconductor test chillers varies by industry. When selecting the type of the semiconductor test chiller, we can select the type according to the following points.

  1. Temperature range: When selecting a semiconductor test chiller, the factory’s requirements for refrigeration temperature should be considered first. The level of refrigeration temperature has important practical significance for the selection and system composition of the semiconductor test chiller. For example, a semiconductor test chiller for air conditioning and a semiconductor test chiller for cryogenic engineering often have fundamental differences.

  2. Refrigeration and stand-alone cooling capacity: The cooling capacity of the semiconductor test chiller is directly related to the energy consumption and operation effect of the entire unit, especially when designing a cold station, under normal circumstances, there is no single semiconductor test chiller. The main reason is to consider that when a semiconductor test chiller breaks down or shuts down for maintenance, it will not stop production, but should select a reasonable number of units according to the production situation.

  3. Energy consumption: refers to electricity consumption and steam consumption. Especially when choosing a large-scale semiconductor test chiller, the comprehensive utilization of energy should be considered. Because a large-scale semiconductor test chiller is a device that consumes a lot of energy, for large-scale refrigeration stations for cooling, it should be fully considered. Comprehensive utilization and balance of heat and cold, with special attention to the full utilization of waste steam and waste heat, in order to achieve results.

  4. Vibration will occur during operation, but the frequency and amplitude vary greatly due to different types of units. If there is a requirement for anti-vibration, a semiconductor test chiller with a smaller amplitude should be used, or the foundation and pipeline of the semiconductor test chiller should be damped.

  5. The quality of the cooling water has a great influence on the heat exchanger, and its effect on the equipment is fouling and corrosion, which will not only affect the reduction of the cooling capacity of the semiconductor test chiller, but also lead to heat exchange in severe cases. Tubes are clogged and broken.

  There are many kinds of refrigeration equipment in daily use, but the application range of semiconductor test chiller is relatively wide, it can control the temperature within a specific range, and the refrigeration effect is stable, suitable for use in various industries.
