PCB Test Yield at 70% target pcb test yield: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop target pcb test yield to 70%, then walk the calculation through step by step. Calculate first-pass PCB test yield for controller boards, display drivers, LED controllers, audio boards, power boards, and connected entertainment hardware electronics.

The inputs for this scenario

  • PCBs passing first-pass test: 925 boards (held at the documented default)
  • PCBs tested: 1,000 boards (held at the documented default)
  • Target PCB test yield: 70 % (the input this scenario stresses; the baseline uses 97)

Working through the calculation

  • The calculation starts from the formula this tool documents: PCB test yield rate = PCBs passing first-pass test ÷ PCBs tested × 100.
  • PCB Test Yield rate works out to 92.5 % at these inputs, and this is the headline figure for the scenario.
  • PCB Test Yield gap to target works out to -22.5 points at these inputs.
  • PCBs passing first-pass test works out to 925 count at these inputs.
  • PCBs tested works out to 1,000 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target pcb test yield sits at 97% and the headline result is 92.5 %, this scenario lands almost exactly on the baseline at 92.5 %.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to target pcb test yield, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. First-pass yield doesn't credit boards that pass on retest after rework, so it can understate final shippable yield on lines with high rework recovery.

Results at a glance

  • PCB Test Yield rate: 92.5 % (headline result)
  • PCB Test Yield gap to target: -22.5 points
  • PCBs passing first-pass test: 925 count
  • PCBs tested: 1,000 count
