Analysis of Flux Spraying Ultrasonic flux spraying, with its unique high-frequency vibration atomization technology, offers unparalleled advantages over traditional spraying. Using high-frequency vibrations of 20-150kHz, it evenly atomizes the flux into tiny droplets of 5-50 microns. The coating thickness can be precisely controlled to 0.1-10 microns, eliminating accumulation and leaks. This effectively avoids residual flux caused by excess flux and cold solder joints caused by insufficient flux. Material utilization rates [...]
