How do you calculate final test capacity?

Multiply units per test cycle by available cycles for gross capacity, then multiply by uptime and first-pass yield. With 4 per cycle over 480 cycles at 90% uptime and 97% yield, gross is 1,920 and good tested capacity is 1,676 machines.

What is a good first-pass final-test yield for kiosks?

On a mature self-service line, 96-98% first-pass is healthy. Persistent dips usually trace to one subsystem — bill validator calibration, touchscreen alignment, or network provisioning — not to random test flakiness.

Why does final test become the line bottleneck?

Final test runs a long, serial functional sequence per machine, so its cycle time dwarfs most upstream stations. Even at 4 units per cycle, 10% downtime here erases 192 units of throughput, which upstream capacity cannot recover.

How is final test capacity different from flashing capacity?

Flashing validates firmware on a board; final test validates the whole assembled machine end to end. Cycle times, failure modes, and rework paths differ, so size each station separately even if the formula looks the same.

Should I add a test bay or improve yield first?

Compare the loss lines. Downtime costs 192 units versus 52 for yield in the example, so reducing test-bay stalls or adding a bay generally returns more than chasing the last yield points.

How do I turn cycles into hours for scheduling?

Multiply your final-test cycle time by available cycles. A 3-minute test across 480 cycles is 24 hours of test time, which usually means multiple bays running in parallel to fit a shift.

Vending, Kiosk & Self-Service Equipment calculator

Final Test Capacity Calculator

Final Test Capacity estimates how many fully assembled vending machines or self-service kiosks a final-test station can validate and pass in a shift, after downtime and first-pass failures are removed. Test engineers and line managers use it to confirm the end-of-line functional test cell can clear the day's build without becoming the bottleneck that strands finished units on the floor. It is the metric that separates how many machines you built from how many are actually cleared to ship. Because final test exercises coin/note handling, touchscreen, network, and dispense in one run, its cycle time is long and its capacity is often the tightest constraint in the whole line.

What this calculator does

Estimate final test capacity for vending, kiosk and self-service equipment using production-ready inputs so teams can confirm whether capacity can cover demand before committing the schedule.
Use it when final test capacity in vending, kiosk and self-service equipment is being asked to take on more work and you need to know if there is room.
It computes good, passed machines per shift by multiplying units per test cycle and available cycles, then derating for station uptime and first-pass test yield.

Formula used

Gross final test capacity = final test capacity output per cycle × available final test capacity cycles
Good final test capacity = gross capacity × expected final test capacity uptime × expected final test capacity first-pass yield

Inputs explained

Units tested per test cycle:
Available final-test cycles in the shift:
Final-test station uptime:
First-pass final-test yield:

How to use the result

Use it when planning end-of-line functional test throughput, sizing test bays, or checking whether final test can keep up with assembly output.
It assumes a consistent test cycle and flat uptime and yield, so it overstates capacity when failures cluster around a bad component lot or a firmware regression triggers long retests.

Current U.S. benchmarks

Global copper trades at $13,484 per tonne (IMF via FRED, May 2026), up 41.5% in a year, and U.S. industrial electricity averages 8.66 cents per kWh. Both feed electrified-hardware unit economics.
Steel mill PPI stands at 348.53 (BLS, May 2026), up 6.7% from a year earlier. New factory orders are up 2.3% year over year (Census).
