Board notes
Soft Start
The opening checks for a fresh PCB come before the line moves into normal output. It focuses on the first boards, print quality and machine state so the build starts with controlled settings, not guesswork.
A soft start on an SMT line is not about moving slowly. It is about warming up the day properly with stencil checks, paste condition, first-board verification and machine status before volume begins. Soft Start turns that routine into a usable note for electronics teams on local production floors.
Teams in Gauteng, KZN and the Western Cape use it to capture stencil condition, paste behaviour and first-piece findings under South African production conditions.
Opening checks before volume
- Plant and shift identified
- First printed board photo saved
- Gerber or drawing revision noted
- Operator and technician names captured
Use the related process pages after this one. The journal follows line observations, while equipment pages tie the note back to the printer, pick and place unit or oven involved in the start-up.
How Soft Start helps when a reflow run first opens
Soft Start covers the first controlled boards of a new PCB on the SMT line. It helps OEM teams bring a fresh build into production with fewer setup changes and less early drift. Use it when the line is ready but the process still needs a measured opening pace.
Write down the PCB name, revision and the line conditions present at start of shift. Inland dust, coastal humidity, load-shedding and dispatch times can all affect paste handling, verification timing and how many opening boards should be held for review. At electronics sites in Johannesburg, Durban, Cape Town and smaller industrial areas, one early check can prevent a longer stop later in the day.
Capture the first board state before settings are adjusted after print or placement. A short sheet kept at the line helps the next shift see stencil wipe frequency, feeder changes and the reason a value was altered. That record is often more useful than trying to reconstruct the opening run from memory after scrap appears.
Records kept after first boards
The result should be a clear record of starting conditions, approved first-board checks and any setting changes made before throughput increased. One traceable Soft Start note is more useful than a loose set of messages when a reflow question or placement fault must be reviewed later.
Link Soft Start to the matching reflow page and a Board notes entry before expanding the build record. Check labels, held boards and operator records once more before dispatch paperwork is closed. SMT line enquiries should name the board type, the placement volume and the machines already on the line.
- Checks matched to your PCB
- Opening print recorded before changes
- Message trail kept with the run
South African start-up conditions
Soft Start has to fit local logistics and the way electronics plants actually open a run. OR Tambo freight timing, Sunnyrock dispatch cut-offs and older factory services around Gauteng can influence when a first-piece record is signed off and when packed boards must leave. If the line is carrying over from a previous product, note that clearly before the new PCB begins.
Coastal air can change paste response and cleaning intervals, especially when the stencil has been standing before shift start. Inland dust affects covers, sensors and feeder tracks, while power interruptions can force repeated machine checks and another first-board approval. A demonstration run should show print, placement and oven behaviour, not just machine movement.
