Reflow
Audit Week
An SMT path prepared for audit week on South African factory floors, written for teams who already run the job.
Reflow checks before the auditors arrive
Audit Week on this reflow page is aimed at SMT teams preparing evidence for an internal audit, customer review, or purchasing file. The focus is on oven settings, traceability records, machine condition, and the small line habits that usually get questioned when boards are under scrutiny.
Audit prep changes with the board mix, shift pattern, and the risk most likely to stop output on site. Highveld dust, coastal humidity, load-shedding windows, and courier handover times all affect how reflow evidence should be gathered and logged. Johannesburg, Durban, Cape Town, and smaller electronics operations each need different notes, especially where a live demonstration run carries more weight than another file.
Photograph the oven area, loader, and finished board racks before labels are moved or bins are tidied. Include the latest profile printout, any red-tagged issue, and the exact point where operators are stopping to recheck boards. That gives the audit pack a usable record of line condition instead of a cleaned-up version assembled afterwards.
What the pack should contain
The handover should identify the product code, oven recipe, inspection points, and the gap that triggered the review. One clear route through incoming material, placement, reflow, and packed output is more useful than a stack of generic notes with no link to the boards on the trolley.
Pair Audit Week with the matching reflow note and a board record before expanding the scope of the review. Check labels, logged temperatures, and sealed cartons one last time before dispatch leaves site. SMT line enquiries should name the board type, the placement volume and the machines already on the line.

South African audit pressure points
Planning for audit preparation here often means fitting checks around dispatch deadlines, customer visits, and shared factory space. OR Tambo export timing, regional courier handovers, and older industrial premises can all affect how evidence is gathered and stored. Teams running mature SMT equipment should note where a workaround exists rather than writing as if the line is a new installation.
At coastal plants, salt air and moisture can shorten cleaning intervals on exposed metalwork and affect how consumables are stored. Inland sites often need more frequent attention on covers, rails, and sensor areas where dust settles through the day. Where power dips occur, capture first-off records and restart checks at the moment they happen, not from memory later on.

Details worth sending with Audit Week
Brief Audit Week with site photos, production timing, and details of what has already gone wrong on the line. Keep the subject line direct.
Send the board name, top and bottom side status, target throughput, and any reject pattern seen after reflow. It also helps to note whether the issue is tied to a single oven zone, one shift crew, a feeder position, or a batch of components. Those specifics make the audit note useful to production, quality, and purchasing at the same time.
