Solder mask processing covers machines and steps used to apply, pattern, and cure solder mask on printed circuit boards (PCBs). Typical equipment includes screen and spray coaters, dispensers, UV/thermal cure ovens, and inspection stations. These systems control mask thickness, registration and adhesion to protect traces during soldering and prevent shorts. Buyers focus on throughput, registration accuracy, chemical compatibility, ease of cleaning, and serviceability.
Inspect machine condition, maintenance records and service history. Verify registration accuracy, lamp hours (UV), oven temperature control, pumps and seals, and cleanliness to avoid contamination. Request demos with your board types and confirm software versions and spare-part availability.
Drain and remove all chemicals, secure moving parts, pack fragile optics and lamps separately, and use heavy-equipment carriers experienced with PCB machinery. Consider climate-controlled transport, adequate crating, full insurance, and correct hazardous-material paperwork for any residues.
Perform daily cleaning of nozzles, squeegees and filters; check UV lamp intensity and oven profiles; replace seals, wipers and consumables on schedule; calibrate registration regularly; and keep critical spares (lamps, pumps, filters) on hand.
