Polyimide Coating System The following is some information about polyimide coatings: Basic Concepts: - Definition: The "PI" in PI coating stands for polyimide, a high-performance synthetic polymer. PI coatings are primarily composed of polyimide, an aromatic heterocyclic polymer containing imide groups in its molecular structure. - Characteristics: Polyimide exhibits excellent thermal stability, mechanical strength, and chemical stability, which contribute to the excellent performance of PI coatings. Performance Characteristics: [...]

Ultrasonic Spraying Machines Apply Photoresist onto Glass Ultrasonic spraying machines utilize ultrasonic vibrations to create an atomization effect. They are suitable for small-batch production and qualitative testing in scientific research laboratories. When applying photoresist onto glass, ultrasonic sprayers can provide uniform and efficient thin-film coatings. Ultrasonic spraying technology demonstrates advantages for directly applying photoresist coatings onto MEMS wafers and other 3D microstructures, particularly on the sidewalls and tops [...]

Ultrasonic Spraying Laser Cutting Protective Liquid In today's increasingly sophisticated laser cutting technology, especially for high-precision processes such as cover cutting, a seemingly small but far-reaching challenge is becoming increasingly prominent: pollution during the cutting process. When a high-energy laser beam acts on the surface of a material, the intense high temperature generated in an instant not only causes the material to melt and vaporize, but also emits [...]
