Printed Electronics & Flexible Hybrid Electronics calculator

Inspection Capacity Calculator

Inspection Capacity tells you how many good, dispositioned panels an AOI or optical inspection cell can actually clear in a run, not just how many it theoretically touches. In printed electronics and flexible hybrid electronics (FHE), roll-to-roll and sheet-fed lines feed inspection stations that must keep pace with printing, sintering, and component attach. Process engineers and line supervisors use it to right-size inspection staffing and machine time so QC does not become the bottleneck. It matters because a printed conductor defect missed here becomes a scrapped assembly three stations downstream.

What this calculator does

  • Inspection Capacity tells you how many good, dispositioned panels an AOI or optical inspection cell can actually clear in a run, not just how many it theoretically touches.
  • Use it when inspection capacity in printed electronics and flexible hybrid electronics is being asked to take on more work and you need to know if there is room.
  • It computes the number of good inspected units a cell can produce per run after applying uptime and inspection yield to gross cycle throughput.

Formula used

  • Gross inspection capacity capacity = units per cycle × available cycles
  • Good capacity = gross capacity × uptime × yield

Inputs explained

  • Panels inspected per index cycle:
  • Inspection cycles available per shift:
  • Inspection station uptime:
  • Inspection first-pass yield:

How to use the result

  • Use it when balancing an inspection station against upstream printing or attach throughput, or when quoting an inspection sub-contract by the shift.
  • It assumes uptime and yield are stable averages; a single web break or a substrate lot with heavy registration drift will blow past these figures for that run.

Current U.S. benchmarks

  • The producer price index for copper and brass mill shapes stands at 559.593 (BLS, May 2026), up 76.8% from a year earlier. Quotes priced off last quarter's material cost miss this move. Global copper trades at $13,484 per tonne (IMF via FRED, May 2026).
  • The U.S. has 11,261 computer and electronic products establishments employing about 815,443 workers (Census County Business Patterns, 2023).

Common questions

  • How do you calculate inspection capacity? Multiply units per cycle by available cycles to get gross capacity, then multiply by uptime and yield. With 4 units/cycle, 480 cycles, 90% uptime and 97% yield you get 1,920 gross and 1,676 good units.
  • Why is good capacity lower than gross capacity? Gross (1,920 units) assumes the station never stops and every unit passes. Real uptime removes 192 units and yield losses remove another 51.84, leaving 1,676 good inspected units.
  • What is a good inspection uptime for printed electronics AOI? Well-run AOI and web inspection cells hold 88-95% uptime; below 85% usually points to frequent recalibration, substrate feed jams, or false-call reviews stealing operator time.
  • Should yield here be inspection pass rate or process yield? Use the inspection station's own effective throughput yield — units that clear inspection without being pulled for re-scan or manual review — not the upstream printing yield.
  • How do I raise good inspection capacity without buying a machine? Cutting false-call rates lifts effective yield, and reducing changeover and reference-image reloads lifts uptime. Moving uptime from 90% to 94% here alone would add roughly 74 good units per run.
