Feeder Setup Time Calculator

Feeder setup can dominate high-mix SMT schedules, especially when offline carts, verification, moisture-sensitive parts, and barcode traceability are involved. This calculator turns feeder count into a practical setup-time estimate for scheduling and quote assumptions.

What this calculator does

  • Estimate SMT feeder setup minutes from feeder count, verified setup pace, and changeover allowance.
  • an SMT supervisor needs to schedule changeover labor before releasing a high-mix build
  • Returns the estimated changeover minutes required to prepare and verify SMT feeders.

Formula used

  • Base feeder loading time = feeders to load or verify ÷ verified feeder setup pace
  • Estimated feeder setup time = base feeder loading time × kitting and verification allowance factor

Inputs explained

  • Feeders to load or verify: Count feeders that must be loaded, exchanged, scanned, or verified for this setup.
  • Verified feeder setup pace: Use the actual pace for trained operators with your feeder carts and traceability rules.
  • Kitting and verification allowance: Add allowance for missing reels, MSD checks, barcode scans, polarity checks, and offline cart movement.

How to use the result

  • Use it for high-mix scheduling, quote setup assumptions, and deciding whether offline setup carts or common feeder strategy will pay off.
  • It assumes feeder count drives setup effort; it does not separately model stencil change, program download, first article, AOI program checks, or material shortages.

Common questions

  • What does the feeder setup time calculator tell me? It estimates setup minutes for loading and verifying feeders before an SMT run.
  • Which numbers should I enter? Use the feeder count from the program/BOM, a measured feeders-per-minute setup pace, and an allowance for your verification process.
  • How should I use the result? Use the result to reserve operator time, stagger changeovers, quote setup labor, or justify offline feeder preparation.
  • When is this only an estimate? Treat it as a planning estimate when product mix, setup time, operator assist time, feeder readiness, inspection disposition, test escapes, scrap, or supplier yield differs from the data used for the inputs.
