ICT Test Time Calculator

ICT time includes fixture cycle time, contact verification, barcode handling, and retest loops. This calculator gives test engineers a practical minutes estimate for a board family or test queue.

What this calculator does

  • Estimate in-circuit test minutes from boards to test, tested-board rate, and debug/retest allowance.
  • a test engineer is scheduling ICT tester time for a PCB assembly lot
  • Returns the ict test time value for the selected electronics manufacturing scope.

Formula used

  • Base ICT cycle time = boards requiring ICT ÷ ICT tested-board rate
  • Estimated ICT test time = base ICT cycle time × debug and retest allowance factor

Inputs explained

  • Boards requiring ICT: Use a current, same-scope value for boards requiring ict from the traveler, MES, ERP, test log, quote, or validated engineering estimate.
  • ICT tested-board rate: Use a current, same-scope value for ict tested-board rate from the traveler, MES, ERP, test log, quote, or validated engineering estimate.
  • Debug and retest allowance: Use a current, same-scope value for debug and retest allowance from the traveler, MES, ERP, test log, quote, or validated engineering estimate.

How to use the result

  • Use it when production, quality, test, procurement, or estimating teams need a defensible number before schedule or quote decisions.
  • It is an estimate and does not replace detailed routing, validated test programs, supplier DFM feedback, thermal profiling, capability studies, or yield-analysis models.

Common questions

  • What does the ict test time calculator tell me? It gives a ict test time result using electronics, PCB, or semiconductor production inputs that match the same lot, board family, wafer lot, or shift.
  • Which numbers should I enter? Use current values from CAD/CAM, BOM, MES, test logs, supplier quotes, or process records; keep the count, time, yield, and cost basis consistent.
  • How should I use the result? Use the result to support capacity checks, quote rollups, yield reviews, staffing decisions, material planning, or process-improvement priorities.
  • 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.
