Photonics Assembly Labor at 29% cleanroom handling and cure allowance: a worked example

Push cleanroom handling and cure allowance up to 29% and the picture changes. This example computes every intermediate figure at that operating point. Use this when planning staffing for a photonics assembly cell, quoting labor for a build-to-print order, or deciding whether to add a second shift to meet delivery.

The inputs for this scenario

  • Number of modules to assemble: 48 units (unchanged)
  • Assembly rate per technician: 2 units / hr (unchanged)
  • Cleanroom handling and cure allowance: 29 % (raised for this scenario; the documented default is 25)

Working through the calculation

  • Applying the documented formula (Base assembly time = number of modules / assembly rate per technician) to the inputs above produces each figure below.
  • At this operating point the engine returns 30.96 hr for total assembly labor (with allowance), the number this scenario is built around.
  • At this operating point the engine returns 24 hr for base assembly time.
  • At this operating point the engine returns 29 % for cleanroom handling time added.
  • At this operating point the engine returns 2 pieces / min for assembly rate per technician.

How this compares with the baseline

  • Against the tool's baseline example, where cleanroom handling and cure allowance sits at 25% and the headline result is 30 hr, this scenario comes in 3.2% above the baseline at 30.96 hr.
  • It computes total assembly labor hours by dividing module count by the per-technician assembly rate and inflating that base time by a cleanroom handling and cure allowance. 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

  • Total assembly labor (with allowance): 30.96 hr (headline result)
  • Base assembly time: 24 hr
  • Cleanroom handling time added: 29 %
  • Assembly rate per technician: 2 pieces / min
