Ultrasonic Spraying of Photoresist onto Alumina Ceramics
Ultrasonic Spraying of Photoresist onto Alumina Ceramics Ultrasonic spraying of photoresist onto alumina ceramics is a common microelectronics manufacturing technology used to prepare high-quality fine patterns. The following are the basic steps and precautions for ultrasonic spraying of photoresist onto alumina ceramics: Steps: Photoresist solution preparation: Prepare the photoresist solution. Photoresist is usually mixed with a solvent (such as acetone, isopropyl alcohol, etc.) to make a sprayable solution. The concentration [...]
