How do I calculate overall yield for a multi-chiplet package?

Multiply the step yields together: die attach, flip chip bonding, underfill, and each chiplet's assembly yield compound into overall packaged yield. The Advanced Packaging Yield calculator does this stacking so you can see how a 99 percent step yield across six operations still lands near 94 percent. Because each package carries multiple known-good die, use Package Scrap Value to weight yield loss by the die value at risk, not just unit count.

What does a test escape cost compared to catching it at final test?

A test escape shipped to a customer can cost 10 to 100 times more than a unit caught at final test once returns, failure analysis, and line-down liability are included. Test Escape Cost combines your escape rate, units shipped, and cost per field failure. Compare it against added Package Test Cost and Final Test Throughput impact to decide whether more test coverage or tighter binning pays for itself.

How much wafer sort or final test capacity do I actually have?

Wafer Sort Capacity and Final Test Throughput derive units per hour from insertion time, index time, sites per touchdown, and yield, then scale by Handler Utilization and uptime. A prober or handler running at 65 percent utilization has substantial hidden capacity. Feed the results into Semiconductor Line OEE to separate availability, performance, and quality losses before you commit to buying another tester.

How do I estimate probe card and test program cost per unit?

Probe Card Cost amortizes card price and touchdown-limited lifetime across the wafers it will test, so a high-pin-count card spread over few lots drives up cost per die fast. Test Program Workload captures development and maintenance effort per device. Roll both into Package Test Cost alongside tester time and handler depreciation to get a defensible cost per tested unit for quoting.

How much underfill and substrate cost goes into each package?

Underfill Usage estimates dispensed volume per package from die gap, fillet, and coverage, converting it to grams and cost per unit, which matters at high volume where a few milligrams per part adds up. Substrate Cost tracks the laminate or organic interposer, often the single largest bill-of-material item in an advanced package. Together they anchor the material side of your per-unit cost and feed Advanced Packaging ROI.

When does an advanced packaging line investment pay back?

Advanced Packaging ROI weighs equipment and facility capital against margin per package, expected volume, and yield ramp. Higher starting yield from Advanced Packaging Yield and lower Packaging Rework Cost shorten payback significantly. Model a conservative yield learning curve and realistic Handler Utilization rather than nameplate capacity, since back-end lines rarely hit theoretical throughput in the first year of a new package.
