Product Description:Chemical MechanicalCMPPolishingCooling Water Temperature Control EquipmentProduct Introduction1. In the field of semiconductor chip manufacturing, the surface treatment process of silicon wafers requires a flat surface during exposure to effectively avoid light scattering and achieve image transfer. Chemical Mechanical Polishing (CMP) is used to meet standard process requirements. As semiconductor chip manufacturing processes advance to the millimeter level, CMP is necessary to achieve the required flatness of the silicon wafer surface.2. The relative motion between the silicon wafer and the polishing pad generates friction, causing the temperature of the polishing pad to rise, potentially reaching up to 80°C. The optimal temperature range for the polishing pad is 30°C to 75°C. If the temperature falls below 30°C or exceeds 75°C, the chemical reaction characteristics between the polishing slurry and the silicon wafer surface deteriorate, affecting the flatness of the wafer surface. Therefore, a Chemical Mechanical CMP Polishing Cooling Water Temperature Control Equipment is required to regulate the water temperature.3. The Chemical Mechanical CMP Polishing Cooling Water Temperature Control Equipment provides low-temperature chilled water to cool the cooling device of the polishing belt in the CMP polisher, addressing the issue of high polishing belt temperatures during operation. The cooling system includes a chilled water tank and a water pump, with the chilled water tank in contact with the polishing surface of the belt, effectively reducing the temperature of the polishing belt during operation.Equipment ApplicationThe cooling of the built-in cooling device in double-sided Chemical Mechanical CMP polishing of silicon wafers utilizes the cold source provided by the Chemical Mechanical CMP Polishing Cooling Water Temperature Control Equipment. The regulation system and display control system allow real-time monitoring of the working temperature via the display panel. The cooling water flows through the cooling channels to cool the lower polishing plate, effectively controlling the processing temperature of the silicon wafer, improving the surface quality of CMP polishing, and reducing the breakage rate of silicon wafers.Product AdvantagesAs a temperature control system for Chemical Mechanical CMP polishing, the Chemical Mechanical CMP Polishing Cooling Water Temperature Control Equipment regulates the polishing temperature, ensuring the silicon wafer temperature remains controlled during polishing.

Product Description:Anodizing Solution Cooling and Heating UnitUnit Introduction1. Electroplating: Electroplating is the process of applying a thin layer of other metal or alloy onto the surface of certain metals using electrolysis. During electroplating, an electrolyte containing ions of the plating metal is typically used as the electroplating solution. The metal product to be plated is immersed in the electroplating solution and connected to the negative terminal of a DC power supply as the cathode, while the plating metal serves as the anode, connected to the positive terminal. A low-voltage direct current is applied, causing the anode metal to dissolve into the solution as cations, which move toward the cathode. These ions gain electrons at the cathode and are reduced to metal, coating the metal product that requires plating.2. Anodizing: A treatment process where metal or non-metal products serve as the anode in a specific electrolyte under particular working conditions. Through the action of direct current, an anti-corrosion oxide film is formed on their surface.3. The temperature of electroplating and anodizing solutions is controlled by the anodizing solution cooling and heating unit. The temperature is adjustable, maintaining the solution within the required range for electroplating and anodizing, thereby improving the yield rate of electroplated and anodized products.4. To meet industry requirements for corrosion resistance, heat exchangers made of titanium or 316 stainless steel are used. Temperature control enhances productivity and product quality. In the electroplating, anodizing, and electrophoretic industries, the anodizing solution cooling and heating unit helps stabilize metal and non-metal ions, allowing metal ions to quickly adhere to electroplated, anodized, or electrophoretic products. This reduces the number of electroplating and anodizing cycles and increases productivity.Unit Features:1. Stable Performance: The unit employs multiple compressors in parallel, each with its own independent refrigeration circuit, including separate evaporators and condensers. All compressors are controlled by a unified microcomputer system, starting and stopping sequentially without interference. With all components made from genuine parts, the failure rate is extremely low, ensuring stable performance and continuous long-term operation without the need for backup units.2. Energy Efficiency: The use of multiple small to medium-power compressors in parallel minimizes grid disturbance during startup and shutdown. The unit automatically determines the number of compressors to operate based on load changes, ensuring optimal working conditions and effective energy savings.3. Long Service Life: The evaporator and condenser are designed rationally and positioned above the compressor. During operation, most of the oil remains in the compressor, ensuring good lubrication.4. Scientifically designed with optimized technical parameters, the unit features advanced and reasonable performance indicators. Custom modifications are available to meet user requirements for different performance specifications.Refrigeration PrincipleThe compressor operates, converting low-temperature, low-pressure gaseous refrigerant into high-temperature, high-pressure gaseous refrigerant, which enters the condenser. Part of the heat from the refrigerant in the condenser is expelled by external cooling water or cooling fans. After releasing heat, the refrigerant liquefies into a high-temperature, high-pressure liquid and flows through a dryer filter for drying and filtration. It then passes through an expansion valve for throttling (rapid cooling) and pressure reduction, becoming a low-temperature, low-pressure liquid that enters the evaporator for heat exchange. The low-temperature, low-pressure liquid refrigerant absorbs heat from the surrounding medium (anodizing solution). During heat absorption, the refrigerant temperature remains constant while its volume changes. The absorbed heat turns the low-pressure liquid refrigerant into a low-temperature, low-pressure gas, which returns to the compressor. After compression, it becomes a high-temperature, high-pressure gas and re-enters the condenser, completing the refrigeration cycle. This effectively cools the anodizing solution, maintaining it at the desired temperature.Heating PrincipleBased on the refrigeration principle, the compressor operates, converting low-temperature, low-pressure gaseous refrigerant into high-temperature, high-pressure gas. This gas passes through a four-way valve and a liquid storage tank before entering the condenser. The heat in the condenser is utilized to heat water in a tank, with water temperatures reaching up to 90°C. After releasing heat, the refrigerant liquefies into a high-temperature, high-pressure liquid and flows through a dryer filter for drying and filtration. It then passes through an expansion valve for throttling and pressure reduction, becoming a low-temperature, low-pressure liquid that enters the evaporator for heat exchange. The low-temperature, low-pressure liquid refrigerant absorbs heat from the surrounding medium (water or oil). During heat absorption, the refrigerant temperature remains constant while its volume changes. The absorbed heat turns the low-pressure liquid refrigerant into a low-temperature, low-pressure gas, which returns to the compressor. After compression, it becomes a high-temperature, high-pressure gas and re-enters the condenser, completing the air-source heat pump cycle. This effectively heats the anodizing solution, bringing it to the required temperature for electroplating or anodizing.Unit Advantages:1. Human-machine interface with microcomputer control panel, adjustable cooling and heating temperature from 5°C to 55°C. The control system uses modular design with multiple built-in protection features. Faults are promptly alerted and displayed. Electronic temperature control with dual digital display and automatic memory function.2. Brand new imported compressors with higher energy efficiency ratio. The condenser features a shell-and-tube design, and the evaporator uses high-efficiency inner-grooved copper tubes for improved heat transfer and easy cleaning.3. High-flow, high-lift water pump from Taiwan, ensuring safe, ultra-quiet, and energy-efficient operation. The unit's exterior is coated with electrostatic powder paint for an elegant appearance. Equipped with a stainless steel water tank for easy and quick cleaning. The tank includes a float ball automatic water replenishment device to measure and control water levels, saving time and improving efficiency.4.
