The film coating machine is a kind of equipment widely used in the preparation of thin films and coating films. In the coating application of solder resist ink, the film coating machine can achieve precise coating thickness and uniform coating quality, thereby improving the performance and service life of solder resist ink.
Membrane method
The film making method of the film coating machine can be carried out according to the following steps:
Prepare the substrate: First, the substrate needs to be prepared, that is, the surface of the material that needs to be coated with solder resist ink. Substrates should be dry, clean, flat, and have a smooth surface.
Preparation of solder resist ink: The prepared solder resist ink needs to be preheated and stirred on the film coating machine to ensure its uniformity and fluidity.
Adjust coating thickness: According to the required coating thickness, the coating speed and coating pressure of the film coating machine can be adjusted to achieve the required coating thickness.
Coating: Put the preheated and stirred solder resist ink into the film coating machine, and then start the film coating machine for coating.
Drying: After the coating is completed, the substrate needs to be placed in a drying chamber for drying, so that the solder resist ink can form a firm film on the substrate.
Inspection: Finally, the prepared film needs to be inspected to ensure that its quality and performance meet the requirements.
In short, the film coating machine is a very important equipment, which plays an important role in the preparation process of solder resist ink. Through reasonable coating parameters and film-making methods, high-quality, high-performance solder resist ink films can be prepared.
