LED Module Count at 99% smt line uptime: a worked example

This scenario runs the led module count calculation on the strong side: 99% smt line uptime, with every other input held at its documented default. Use it when led module count in signage, displays and architectural graphics is being asked to take on more work and you need to know if there is room.

The inputs for this scenario

  • LED modules populated per pick-and-place cycle: 4 units / cycle (unchanged)
  • Placement cycles available per shift: 480 cycles (unchanged)
  • SMT line uptime: 99 % (raised for this scenario; the documented default is 90)
  • First-pass module yield: 97 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross LED module count capacity = units per cycle × available cycles) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,844 units for good output capacity, the number this scenario is built around.
  • At this operating point the engine returns 1,920 units for gross capacity.
  • At this operating point the engine returns 19.2 units for uptime loss.
  • At this operating point the engine returns 57.02 units for yield loss.

How this compares with the baseline

  • Against the tool's baseline example, where smt line uptime sits at 90% and the headline result is 1,676 units, this scenario comes in 10% above the baseline at 1,844 units.
  • Use it when sizing a shift or a job for LED video walls, ticker displays, or modular signage where modules are produced in repeatable placement cycles. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Good output capacity: 1,844 units (headline result)
  • Gross capacity: 1,920 units
  • Uptime loss: 19.2 units
  • Yield loss: 57.02 units

Run it with your numbers

  • Every input above is editable in the live LED Module Count calculator, which recalculates instantly and can be shared with the inputs intact.
