Function focus: The glue homogenizer is mainly used to evenly mix adhesives, coatings, adhesives and other materials, and apply them evenly on the substrate after mixing. Spin coating equipment mainly focuses on preparing thin and uniform films on substrates, such as optical films, battery films, conductive films, etc.

Structural composition: The main structural components of the glue homogenizer include a mixing drum, mixer, motor, reducer, etc. The mixing of materials is achieved through the rotation of the mixer, and then the centrifugal force generated by the rotation is used for coating. Spin coating equipment usually includes a turntable, feeder, scraper, nozzle, motor, etc. Its focus is on precise control of the liquid coating process, forming a thin film through the rotation of the turntable and the flow of the liquid.

Coating accuracy: The glue spreader has high requirements for mixing viscosity, temperature, etc., but the coating accuracy is relatively low. Spin coating equipment is mainly used for thin film coating, with high coating accuracy requirements, generally reaching tens of nanometers.

Application scenario: The glue spreader is widely used in fields such as electronic packaging and printed circuit board manufacturing, for coating materials such as glue and solder resist. Spin coating equipment is mainly used in semiconductor manufacturing, optical device preparation, scientific research experiments and other fields, for coating photoresist, preparing functional thin films, etc.

In fact, in many cases, the functions of the glue spreading machine and the spin coating machine are similar, and the boundary between the two is not very clear. Some equipment may have both glue spreading and spin coating functions at the same time.
