SMT Line Restart After Planned or Emergency Shutdown: Parts Inspection SOP 2026
After a weekend, holiday, power-curtailment, or typhoon shutdown, an SMT line that is simply powered back on will fail its first board. This 2026 field SOP grades restart tasks by shutdown duration (under 24h, 1-3 days, 4-7 days, over 7 days) and lists the spare-parts checks for feeders, nozzles, stencils, and reflow ovens that bring first-board yield back above 95% inside two hours. Includes an emergency parts checklist and typhoon / power-curtailment handling for plants in southern China, Southeast Asia, and Mexico. Written for line engineers, maintenance leads, and shift supervisors running Yamaha, Fuji, Panasonic, ASM, and Hanwha SMT lines.
