How do you calculate lamination yield?

Divide affected pieces by total laminated pieces to get the defect rate. With 8 affected out of 250 the rate is 3.2%, and the gap to a 95% reference is 91.8 points as reported here.

What is a good lamination yield in flexible electronics?

Mature FHE lines target 95%+ good lamination, so a defect rate under 5% is generally acceptable. A 3.2% affected rate is comfortably inside that band.

Why does the calculator show a 91.8-point gap?

The gap subtracts the calculated 3.2% affected rate from the 95% target, producing 91.8 points here. It's a raw point comparison, so read it as distance from the target figure rather than as a pass/fail verdict on its own.

What causes lamination defects?

Trapped air, misaligned nip pressure, aged or under-cured adhesive, incorrect roll temperature, and substrate contamination are the usual culprits. Each shows up as bubbles, wrinkles, or delamination.

Lamination yield vs die-cut yield — how do they differ?

Lamination yield measures bonding quality; die-cut yield measures clean singulation. A part can laminate perfectly and still fail at die-cut, so both are tracked separately along the line.

How do I improve lamination yield?

Stabilize roll temperature and nip pressure, verify adhesive shelf life, add a de-gassing or vacuum step, and keep substrates clean. Trend the defect rate by shift to catch drift early.

Printed Electronics & Flexible Hybrid Electronics calculator

Lamination Yield Calculator

Lamination yield tracks how cleanly you bond cover layers, adhesives, and encapsulants onto printed flexible circuits without bubbles, wrinkles, or delamination. In flexible hybrid electronics the lamination step is a frequent source of scrap because it combines heat, pressure, and dissimilar materials that trap air or shear traces. Quality and process engineers watch this metric to catch drifting roll temperature, adhesive age, or nip pressure before a whole batch is compromised. Here the calculator reports the affected-piece rate and the gap between that rate and your target, so you can see at a glance whether the lamination station is in control.

What this calculator does

Lamination yield tracks how cleanly you bond cover layers, adhesives, and encapsulants onto printed flexible circuits without bubbles, wrinkles, or delamination.
Use it when lamination 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 affected-piece rate by dividing failed laminated pieces by the total laminated, and reports the gap in points between that rate and your target.

Formula used

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

Inputs explained

Delaminated or failed laminated pieces:
Total pieces laminated in the batch:
Lamination yield target:

How to use the result

Use it after a lamination run to log defect rate, or during a shift to check whether the station is drifting against its yield target.
It reports rate and gap from raw counts but does not diagnose the failure mode — bubble, wrinkle, or delamination all land in the same affected count.

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).
