Where do the default values come from?

They are illustrative line numbers so each page shows a worked answer. Replace them with your own step yields, test times, wafer maps, prices and the targets in your yield and capacity plans.

Why do some results show a warning?

A warning means the plan fails a limit you entered or one from a cited source, such as rolled yield under your target or a test cell short of weekly demand. The message states the gap and what to change.

Can I download the calculation?

Yes. Every calculator has an Excel workbook with live formulas that match the page, so you can check the math or reuse it in a quote.

Why is a result blank?

An input is missing or outside its valid range, so there is no honest number to show. The message above the result names the input to fix.

Best calculators in this category

Advanced Packaging Yield: Rolled yield of an assembly flow from its step yields, the good units out of a lot, and the step losing the most units.
Wafer Sort Capacity: Wafers one prober can sort each week from dies per wafer, dies tested per touchdown, touchdown time and uptime, against your plan.
Final Test Throughput: Units a final test cell finishes each week from its sites, test time, handler index time, retests and uptime, against weekly demand.
Burn-In Capacity: Devices burn-in ovens can screen each week from boards, sockets, burn-in duration, handling time and oven uptime, against weekly demand.
Chiplet Assembly Yield: Yield of a multi-chiplet module from chiplet count, incoming die quality, bond yield and interposer yield, and the die quality the target needs.
Substrate Cost: Substrate cost per good package from strip price, sites per strip, substrate yield and tooling, with the strips to buy for the build.
Package Test Cost: Final test cost per good device from tester hourly rate, seconds per touchdown, test sites and first-pass yield, against your target.
Die Attach Yield: Die attach yield from dies attached and rejects by mode, voids, bondline or tilt, and placement, against your target, with the mode to fix first.
Wire Bond Workload: Wire bonder hours a body of work needs from wires per unit, time per wire and index time, against the bonder hours available.
Flip Chip Yield: Flip chip yield from good and assembled units, the joint defect rate it implies across the bumps, and the joint rate the target needs.
Underfill Usage: Underfill a flip chip needs per die, from die size, the gap, die thickness, fillet width and the share of the gap the bumps fill.
Package Inspection Load: Inspector hours a lot of packages needs, scanning plus reject reviews, from packages inspected, time per package and reject rate, against the hours available.

Live market signals for this industry

The producer price index for primary nonferrous metals (a broad metals benchmark, not copper alone) stands at 566.01 (BLS, Sep 2026), up 46.1% from a year earlier. Quotes priced off last quarter's material cost miss this move. Global copper trades at $14,473 per tonne (IMF via FRED, Sep 2026).
The producer price index for plastic resins and materials stands at 276.296 (BLS, Sep 2026), up 6.5% from a year earlier. Quotes priced off last quarter's material cost miss this move.
The producer price index for paper (not a paperboard or container index) stands at 282.486 (BLS, Sep 2026), up 10.1% from a year earlier. Quotes priced off last quarter's material cost miss this move.
The U.S. has 11,261 computer and electronic products establishments employing about 815,443 workers (Census County Business Patterns, 2023).
