Spray PCB

Ultrasonic spraying technology is regarded as an effective thin-film coating preparation process, such as photoresist coating on the surface of semiconductor circles. Compared with the traditional spin coating process, ultrasonic spraying can prepare the surface microstructure with better wrapping and more uniformity. photoresist coating. CHEERSONIC Ultrasonic’s ultrasonic precision spraying system provides surface coating solutions for semiconductor photoresist coating, PCB flux spraying, microelectronic sensor functional coating coating, etc.
