1. Overview The spin coater uses the centrifugal coating principle to coat liquid or colloidal materials on silicon, crystal, quartz, ceramics and other substrates to form thin films. This process has a wide range of applications in the field of materials research. The working chamber of the spin coater is made of PMMA, which has the advantages of beautiful, light and easy to observe.

4. Device connection 4.1. Installation location: The installation location should be selected on a flat, stable, spacious and well-ventilated surface. Otherwise, the spinning coating effect may be affected. If you need to deal with glue containing volatile or toxic solvents, be sure to place the equipment in a well-ventilated fume hood. The installation location of the equipment should be away from direct sunlight or cold/heat sources and moisture.
4.4. Loading substrate: Place the substrate to be processed in the center of the tray. The substrate can be wafers, glass slides, small fragments, and other substrates suitable for spinning coating. Notice: The substrate must be larger than and completely cover the surface of the tray. If the selected substrate is smaller than the loading tray, it will cause the glue to flow into the vacuum pipeline of the equipment, thereby blocking or corroding the internal pipeline of the equipment.
5. Experiment operation 5.1. Whole process: 1. Connect the power supply and vacuum pump according to the instructions 2. Install the sample according to the above; 3. Press the power button to enter the operation interface, first set a low-speed (less than 1000rpm) coating program.
