AI USE CASE
SMT Line Job Grouping Optimizer
Cuts feeder changeover time for contract electronics manufacturers by grouping jobs with shared components.
What it is
By analysing BOMs and pick-and-place programs, this tool clusters scheduled jobs by component overlap to minimise feeder swaps between runs. On a typical two-line SMT shop, this removes 20–30 minutes of setup time per shift, translating to 2–4 extra productive hours per week. Over a year, that can recover the equivalent of several full production days and reduce operator fatigue from repeated manual changeovers. Implementation requires only existing job files and a basic scheduling spreadsheet.
Data you need
BOM files and pick-and-place programs for each scheduled job, ideally in a structured format (CSV, XML, or vendor-specific CAD export).
Required systems
- none
Why it works
- Standardise BOM and pick-and-place export formats across all customers before deployment.
- Run the optimizer on a rolling 2–5 day job horizon so it always has enough jobs to find meaningful clusters.
- Involve the line operator in reviewing suggestions to catch practical constraints the algorithm misses.
- Track actual vs. predicted changeover time per shift to validate and continuously improve the grouping logic.
How this goes wrong
- BOM and pick-and-place files are inconsistently named or formatted, preventing reliable component matching across jobs.
- Planners override suggestions based on customer delivery priorities, eroding the optimisation benefit without capturing lessons learned.
- The tool groups jobs well for components but ignores board-size or solder-paste changeovers, leaving hidden setup time on the table.
- Infrequent job scheduling cadence means the optimizer has too few jobs to group at any one time, reducing its impact.
When NOT to do this
Avoid this tool if your shop runs fewer than three to five different jobs per week — the job pool is too small to yield meaningful groupings and manual planning will outperform it.
