Night Shift
Night Shift deals with the staffing, lighting and fault-capture issues that surface after day shift signs off.
How Night Shift runs across an actual production week
Night Shift looks at what changes on an SMT line after day shift signs off. It focuses on staffing handover, lighting at key stations and fault capture when fewer people are on the floor.
Night Shift starts with the handover gap between crews, not with the PCB alone. Note the hours after day shift, the product still on the line, and any site condition that changes visibility or machine checks. In Gauteng, dust on sensors and covers often shows up late; on coastal sites, moisture and salt residue can alter paste behaviour and storage decisions before midnight.
Capture the line state at sign-off while feeder positions, reject bins and oven settings are still untouched. A printed handover card near the printer or placement machine helps the incoming crew record stoppages, nozzle swaps and first faults without guessing what changed earlier. That record matters most when one missing component count can derail the rest of the night run.
After-hours line control points
Night Shift needs tighter discipline once supervision thins out. Expect a clear handover method, lighting checks at inspection points and a fault log that makes sense at 02:00. Night Shift is for builds where placement, reflow and board handling continue after the main team has gone home.
Link Night Shift with the related reflow settings and board history before extending the after-hours batch. Check packed panels, feeder reloads and oven profile notes before dispatch leaves in the morning. SMT line enquiries should name the board type, the placement volume and the machines already on the line.

Overnight conditions on South African SMT lines
Night work on local SMT lines often has to fit around security access, generator changeover and early courier collection. Johannesburg plants may fight dust after doors open and close through the evening, while Durban and Cape Town teams often need stricter storage attention once humidity rises. Older industrial sites also tend to have uneven task lighting at printers, loaders and repair benches.
When power is unstable, record the exact stop point for the printer, placer and oven before production resumes. Fewer technicians on site means feeder verification and reject confirmation cannot be left to memory. A machine demo area or walk-in viewing space needs its own boundary so visitors do not interrupt fault capture on a live build.

Night Shift handover details
Use Night Shift for board builds that need after-hours placement, reflow planning and handover between crews.
File the handover note before the line is released to the incoming crew. Attach placement exceptions, oven changes and any feeder swaps to the same record so traceability stays intact when a defect appears later. Where buyers ask for supporting paperwork, keep Night Shift with the project file and the related resource page.
