Cell Formation Channel Capacity at 66% formation equipment uptime: a worked example

This worked example runs the cell formation channel capacity numbers for a tougher week than the baseline: 66% formation equipment uptime instead of the typical 92%. Estimate good cell output from formation channels, available cycles, uptime, and formation pass yield.

The inputs for this scenario

  • Cells per formation cycle: 1,200 cells/cycle (held at the documented default)
  • Available formation cycles: 18 cycles (held at the documented default)
  • Formation equipment uptime: 66 % (the input this scenario stresses; the baseline uses 92)
  • Formation first-pass yield: 97 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross formation capacity = cells per formation cycle × available formation cycles.
  • Good formed-cell capacity works out to 13,828 cells at these inputs, and this is the headline figure for the scenario.
  • Gross formation capacity works out to 21,600 cells at these inputs.
  • Cells lost to formation downtime works out to 7,344 cells at these inputs.
  • Cells lost to formation rejects works out to 428 cells at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where formation equipment uptime sits at 92% and the headline result is 19,276 cells, this scenario comes in 28.26% below the baseline at 13,828 cells.
  • Use it for capacity planning a formation area, sizing channels against a cell-start target, or quantifying how downtime and reject losses cut into deliverable formed cells. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Good formed-cell capacity: 13,828 cells (headline result)
  • Gross formation capacity: 21,600 cells
  • Cells lost to formation downtime: 7,344 cells
  • Cells lost to formation rejects: 428 cells
