Ultrasonic Semiconductor Wafer Coating
Description:
Wafer coating is a unique process that facilitates the automatic application of chip bonding adhesives at the wafer level, followed by the formation of chip bonding films in the next stage. FUNSONIC's ultrasonic semiconductor wafer coating technology is suitable for wafer coating, which can achieve process speed, thickness control, and material uniformity. After the hot or UVB stage and wafer cutting, chip connections are achieved through heating and pressure to produce consistent adhesive lines and small, controlled corners.
Ultrasonic semiconductor wafer coating technology needs to consider spraying parameters during use, such as ultrasonic frequency, spraying speed, and coating thickness, which need to be optimized according to specific materials and requirements; At the same time, material properties can also have a certain impact on the spraying effect, such as the viscosity, surface tension, and volatility of the coating, which need to be considered when selecting materials.
