How do you calculate die-cut yield?

Divide rejected pieces by the total die-cut, then compare to your target. With 8 rejects out of 250 the reject rate is 3.2% and the gap to a 95% reference is 91.8 points as shown here.

What is a good die-cut yield for flexible circuits?

Well-maintained die-cut stations hold 95%+ good, so a reject rate under 5% is acceptable. The 3.2% here is comfortably inside a healthy range.

What defects lower die-cut yield?

Cracked traces at the cut edge, burrs, torn or fuzzy edges, incomplete cuts, and slug pull are the common rejects. A dull die or bad registration usually drives a cluster of them.

Why is the gap-to-target 91.8 points?

It subtracts the 3.2% reject rate from the 95% target figure, yielding 91.8 points. Treat it as a point distance from the reference number, not as a standalone quality grade.

Die-cut yield vs lamination yield — what's the difference?

Die-cut yield captures singulation and edge quality; lamination yield captures bonding quality upstream. Both use the same rate math but flag failures at different stations, so track them separately.

When should I change or sharpen the die?

When the reject rate trends upward across successive batches — especially with rising burr or incomplete-cut counts — schedule die maintenance before the rate crosses your target rather than after scrapping a roll.

Printed Electronics & Flexible Hybrid Electronics calculator

Die Cut Yield Calculator

Die-cut yield measures how cleanly you singulate printed flexible parts from the web without cracked traces, burrs, torn edges, or slug pull. It's the last major scrap gate on a flexible hybrid electronics line, and because the die contacts already-printed conductors, a dull or misaligned tool can quietly destroy good circuits. Process and tooling engineers track this rate to schedule die maintenance and to decide when kiss-cut depth or registration has drifted out of tolerance. This calculator returns the reject rate and the gap to your yield target so a shift lead can flag a failing die before it eats a whole roll.

What this calculator does

Die-cut yield measures how cleanly you singulate printed flexible parts from the web without cracked traces, burrs, torn edges, or slug pull.
Use it when die cut yield in printed electronics and flexible hybrid electronics needs a clean rate and gap-to-target you can put on a tier board.
It computes the reject rate by dividing die-cut rejects by the total die-cut, and reports the gap in points between that rate and your target.

Formula used

Die Cut Yield rate = affected amount ÷ total amount
Gap to target = target rate - calculated rate

Inputs explained

Die-cut pieces rejected for edge defects:
Total pieces die-cut in the batch:
Die-cut yield target:

How to use the result

Use it after a die-cut run or mid-shift to check whether the cutting tool and registration are holding your yield target.
It aggregates all cut defects into one rate and won't distinguish a dull die from a registration error — you still need to inspect the reject mode.

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).
