PCB Panel Utilization at 56% target panel utilization: a worked example

Suppose target panel utilization falls to 56%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Measure how much fabrication panel area is occupied by sellable board images after rails, coupons, spacing, and tooling keep-outs.

The inputs for this scenario

  • Board image area used: 128 sq in (held at the documented default)
  • Usable fabrication panel area: 180 sq in (held at the documented default)
  • Target panel utilization: 56 % (the input this scenario stresses; the baseline uses 78)

Working through the calculation

  • The calculation starts from the formula this tool documents: PCB panel utilization = board image area used รท usable fabrication panel area.
  • PCB panel utilization works out to 71.11 % utilized at these inputs, and this is the headline figure for the scenario.
  • Panel utilization gap works out to -15.11 points at these inputs.
  • Board image area used works out to 128 sq in at these inputs.
  • Usable panel area works out to 180 sq in at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target panel utilization sits at 78% and the headline result is 71.11 % utilized, this scenario lands almost exactly on the baseline at 71.11 % utilized.
  • Computes panel utilization as board image area divided by usable panel area, and the point gap to your target utilization. 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

  • PCB panel utilization: 71.11 % utilized (headline result)
  • Panel utilization gap: -15.11 points
  • Board image area used: 128 sq in
  • Usable panel area: 180 sq in
