Boards Per Panel at 69% usable panel yield: a worked example

Suppose usable panel yield falls to 69%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate effective boards per manufacturing panel after panel count basis and usable panel yield are applied.

The inputs for this scenario

  • Candidate board images: 72 board images (held at the documented default)
  • Production panels represented: 12 panels (held at the documented default)
  • Usable panel yield: 69 % (the input this scenario stresses; the baseline uses 96)

Working through the calculation

  • The calculation starts from the formula this tool documents: Candidate boards per panel = candidate board images รท production panels represented.
  • Effective boards per panel works out to 4.14 boards / panel at these inputs, and this is the headline figure for the scenario.
  • Candidate boards per panel works out to 6 boards / panel at these inputs.
  • Usable board images works out to 49.68 board images at these inputs.
  • Panels represented works out to 12 panels at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where usable panel yield sits at 96% and the headline result is 5.76 boards / panel, this scenario comes in 28.13% below the baseline at 4.14 boards / panel.
  • Computes candidate boards per panel from image and panel counts, then scales by usable yield to give effective good boards per panel. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Effective boards per panel: 4.14 boards / panel (headline result)
  • Candidate boards per panel: 6 boards / panel
  • Usable board images: 49.68 board images
  • Panels represented: 12 panels
