How do you calculate package test cost?

Multiply devices by the tester cost per insertion by first-pass coverage, add setup, then divide by devices. The default gives 50,000 × $0.28 × 0.92 + $8,000 = $20,880 total, or $0.4176 per device.

What is a good test cost per device?

It varies widely by device: commodity parts run cents while complex packages can run dollars. The default's $0.42 per device is typical for a moderately complex package; the goal is keeping test a small fraction of total package cost.

How does first-pass coverage affect test cost?

Higher coverage generally means more test content and longer insertions, raising variable cost. At 92% coverage the variable portion here is $12,880; deeper testing adds tester time and cost per unit.

How do I reduce package test cost per device?

Cut insertion time, add test sites for parallelism, raise first-pass yield to avoid retest, and amortize the load-board and program setup over larger volumes. The $8,000 setup here adds $0.16 per device at 50,000 units.

What is included in the setup cost?

Test program development and the load-board or interface hardware are one-time charges. This tool treats them as a fixed adder spread across the lot, separate from per-insertion tester time.

Test cost per good device vs per device tested — which is this?

This tool divides total cost by devices tested to give a per-unit figure. If you want cost per good device after fallout, divide instead by the number that passed, which raises the effective cost.

Semiconductor Advanced Packaging & Test calculator

Package Test Cost Calculator

Package test cost is the fully loaded spend to electrically screen finished packages at final test, spread across a lot to reveal the cost per good device. Test engineers, ATE capacity planners, and product cost owners rely on it because tester time is expensive and often the second- or third-largest line in package cost after substrate and assembly. The number is driven by insertion time on the tester multiplied by an amortized machine rate, plus the one-time program and load-board setup. As device complexity and coverage requirements climb, so does insertion time — making this calculation central to whether a test flow is affordable at volume.

What this calculator does

Estimates the final-test cost burden on packaged semiconductor devices.
Use it to weigh tester time, first-pass yield, and program setup when quoting a package test flow.
It computes total final-test spend (variable tester time at your first-pass coverage plus fixed setup) and the resulting test cost per good device.

Formula used

Total = devices x tester cost per insertion x first-pass% + setup
Test cost per good device = Total / devices

Inputs explained

Devices tested at final test:
Tester cost per second of insertion:
First-pass test coverage:
Test program and load-board setup:

How to use the result

Use it when defining a test flow, sizing ATE capacity, or quoting the test line item on a new package.
It uses a flat first-pass coverage and single insertion rate, so it won't model retest loops, multi-site parallelism savings, or binning that changes effective per-good cost.
