The SME-6300 is a mass-production in-line PCBA cleaning machine by Southern Machinery (Shenzhen). Built around a water-based wash unit, DI water rinse unit and two-stage hot-air dry unit, it clears rosin flux, no-clean flux, water-soluble flux, solder paste balls and organic residues from telecom, medical-device, digital-meter and automotive PCBA — without taking boards off the line.
