Cooling and heating system TES for integrated circuit wafer cooling method

Integrated circuit products have been developed for more than 50 years and are the most advanced high-tech industries. Integrated circuit or chip / chip. The complete chip manufacturing process includes chip design, wafer manufacturing, package manufacturing, and testing. The wafer manufacturing process is particularly complicated.The raw material of the chip is silicon, and the silicon is refined by quartz sand. The wafer is purified by silicon (99.999%), and then these pure silicon are made...

LNEYA New Energy Electric Vehicle Test Temperature Controlled Cooling and Heating Solution

Reactor Thermal Control Unit and Solutions for Chemicals

Temperature control is a process in which the temperature of a substance or a change in temperature is measured or otherwise detected, and the transfer of thermal energy into or out of the space or substance is adjusted to achieve the desired temperature. When dealing with pharmaceutical production, maintaining accurate temperature control is critical. Starting with research throughout production, precise temperature control is required at every stage of the process. We fully understand the i...

Precautions for cooling and heating during operation of various reactors

In many laboratories, various reaction vessels of chemical companies are indispensable reaction vessels, and its operating temperature: -80°C-250°C. The laboratory reactor works at normal temperature, and cooling water must be passed normally to avoid magnetic reduction and demagnetization of the magnetic steel. For the user, there is no headache than not knowing what kind of temperature control equipment to choose to suit their own test or production requirements. The most common requirement...

The significance of temperature in IC testing

Every integrated circuit (IC) goes through two type of tests before it can be sold and used to build a product: the first is called a wafer test; the second is called final test. With the improvement of integrated circuit electrical test technology and requirements, some chip products have integrated temperature sensors, or through the voltage changes of some precision diodes linearly related to temperature changes, the current actual chip under test is calculated through a series of formulas...

What do the LNEYA chiller fault codes mean? What is the solution?

Q: What is the fault code of the chiller? Answer: E1 means extremely high indoor temperature alarm, E2 means extremely high temperature alarm, E3 means extremely low temperature alarm, E4 means indoor temperature controller failure, E5 means water temperature sensor failure, E6 means water output alarm, etc. . The fault codes of industrial chillers are in different manufacturers. The fault codes are different. According to the different chiller fault codes, it is easier to find the fault prob...

All analysis of refrigerant changing process of industrial chiller unit

Refrigerant is an indispensable part of the refrigeration system of the industrial chiller. During the operation of the industrial refrigeration unit, the refrigerant constantly changes in the industrial refrigeration unit to achieve the cooling effect, so what changes have occurred in the industrial refrigeration unit refrigerant! Let me introduce you to the process of refrigerant changes in industrial refrigeration units. What are the relevant contents? Refrigerant change process of industr...

How to solve the common faults of industrial circulating chillers?

For industrial circulating chillers, if they are always in a high-temperature operating state, a large amount of cold air will be seriously lost. After ensuring the sealing effect of the use environment, effective thermal insulation can be carried out for the industrial chiller in a timely manner to ensure that the industrial circulating chiller is in a stable operating state. Stable operating efficiency can increase the efficiency of lowering the temperature in the unit environment and reduc...
