Boards Per Panel at 99% usable panel yield: a worked example

Push usable panel yield up to 99% and the picture changes. This example computes every intermediate figure at that operating point. a PCB estimator needs a board-per-panel assumption for quoting or supplier comparison

The inputs for this scenario

  • Candidate board images: 72 board images (unchanged)
  • Production panels represented: 12 panels (unchanged)
  • Usable panel yield: 99 % (raised for this scenario; the documented default is 96)

Working through the calculation

  • Applying the documented formula (Candidate boards per panel = candidate board images รท production panels represented) to the inputs above produces each figure below.
  • At this operating point the engine returns 5.94 boards / panel for effective boards per panel, the number this scenario is built around.
  • At this operating point the engine returns 6 boards / panel for candidate boards per panel.
  • At this operating point the engine returns 71.28 board images for usable board images.
  • At this operating point the engine returns 12 panels for panels represented.

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 3.12% above the baseline at 5.94 boards / panel.
  • Computes candidate boards per panel from image and panel counts, then scales by usable yield to give effective good boards per panel. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Effective boards per panel: 5.94 boards / panel (headline result)
  • Candidate boards per panel: 6 boards / panel
  • Usable board images: 71.28 board images
  • Panels represented: 12 panels
