Uniform glue spin coating machineBy rotating the substrate at high speed and utilizing centrifugal force to evenly spread the adhesive solution dropped on the surface of the substrate, a thin film with a thickness ranging from nanometers to micrometers is formed.

　　Uniform glue spin coating machineComposition:

1. Rotating platform: The core component for placing the substrate, usually fixed by vacuum adsorption or mechanical clamping, and made of corrosion-resistant metal or ceramic materials.

2. Drive system: Driven by a high-precision motor, it can accurately control the rotational speed and acceleration, ensuring stable speed.

3. Control system: Automated control is achieved through microprocessors or PLCs, with preset rotation programs. Some models support touch screen operation and data storage.

4. Protective devices: including transparent protective covers, waste liquid collection tanks, and some models are equipped with ventilation systems.

5. Dropping auxiliary device: Some equipment integrates an automatic dispensing system, which can accurately control the dispensing amount and position, reducing human operation errors.

Key parameters:

1. Speed range: usually 100-10000 rpm, some equipment can reach over 20000 rpm, and the speed accuracy directly affects the uniformity of the film.

2. Rotation time: can be set from 0.1 seconds to several minutes, with multiple time speed combinations to meet complex coating requirements.

3. Acceleration/deceleration: Control the speed of speed changes to avoid splashing or uneven distribution of liquid due to severe acceleration.

4. Base size: Supports circular or square shapes, with different compatibility ranges for different models.

5. Vacuum adsorption force: Ensure that the substrate does not shift during high-speed rotation, and the adsorption force needs to be adjusted according to the substrate material and thickness.
