Developing uniform glue Model MS-1000 purification spin coating machine is suitable for developing semiconductor wafers, such as spin coating film for its wide range of uses, including large-scale semiconductor silicon wafers, chip, chips, and other colloids plate surface coating processes spin coating or lithography process. Integrated circuits and semiconductor parts production process, coated with light-induced anti-corrosive coating equipment and special equipment part of the four-position chip microcomputer control of four stations at the same time work or work separately, that the operation of the station alone drive, turn number of individually adjustable and displayed separately. To ensure that the coating process is not fly sheet, equipment tips and pump the middle four solenoid valves, while adding a negative pressure gas tank, to ensure that the suction piece solid and reliable. The device is equipped with a dedicated air cleaning devices. Main Specifications: Main Specifications developing stations: an operator-bit program time: 1-99 seconds developing dry rinse 1-99 seconds 1-99 seconds rotator revolutions: 500-8000 rev / min (adjustable) silicon Disc Diameter: Φ30-Φ75mm purifying effect: US Federal Standard 100 cleanup operations area speed: 0.3-0.5 m / s airflow Status: vertical laminar flow Dimensions: 650Χ750Χ1620mm 1. Control range and accuracy: speed control range is: 500-8000 rpm, accuracy of ± 3% 2. Time control ranges: 1-99 seconds with an accuracy of ± 5% 3. Speed ??adjustment using high-precision D / A converter with 128 precision tuning. 4. View speed intelligent. (Automatic Identification which motor on or off) automatically switch to the open motor. Can be preselected, may also view any motor speed during operation. 5. The use of advanced technology and E2PRAM I2C bus digital memory, process parameters can be stored in 10 groups (A-type spin coater machine can I save 10 delay, 40 motor speed parameter .B machines can I save 20 time parameters, 80 speed parameter; developing machine parameters can be saved nine slow start, 30 hours, 30 speed parameter). Brownout saved parameters is not lost for 10 years. Parameters adjusted automatically saved, simplifying operation. 6. With automatic intelligent control functions, when using automatic mode just put away the piece, and then click ATART (start) button, sucker open automatically after 6 seconds delay the timing of the completion of a parked motor automatically turns off after sucker, horn-ming three times, suggesting the job done. Greatly improve the work efficiency. 7. Time and speed of measurement timing of all controlled by software, part of the use countdown timer display, speed measurement section displayed directly measured the number of revolutions per minute of the motor. Adjust the part controlled by the software, and D / A converters, removed the original use of CMOS circuits using dial switch and mechanical potentiometers mechanical contacts. Based on the original increase of automatic functions, reducing the operating procedures to avoid the key switch on the frequent switch panel, greatly reducing the key switch damaged due to frequent use. Improve the overall reliability and service life. Adjust, start, switch, stop, and there is a beep.
