UV Adhesive Cure Dose at 56% substrate and fixture uv transmission: a worked example

Suppose substrate and fixture uv transmission falls to 56%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate effective UV cure dose from lamp intensity, exposure time, transmission, and process yield.

The inputs for this scenario

  • UV intensity at bond line: 850 mW/cm² (held at the documented default)
  • Exposure time under lamp: 8 s (held at the documented default)
  • Substrate/fixture UV transmission: 56 % (the input this scenario stresses; the baseline uses 78)
  • Cure process first-pass yield: 95 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Theoretical UV dose = UV intensity at bond line × exposure time.
  • Effective UV cure dose works out to 3,618 mJ/cm² at these inputs, and this is the headline figure for the scenario.
  • Theoretical UV dose works out to 6,800 mJ/cm² at these inputs.
  • Transmission loss works out to 2,992 mJ/cm² at these inputs.
  • Process yield loss works out to 190 mJ/cm² at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where substrate and fixture uv transmission sits at 78% and the headline result is 5,039 mJ/cm², this scenario comes in 28.21% below the baseline at 3,618 mJ/cm².
  • It computes the effective UV cure dose reaching the adhesive after accounting for substrate/fixture transmission losses and the fraction of parts that cure correctly. 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

  • Effective UV cure dose: 3,618 mJ/cm² (headline result)
  • Theoretical UV dose: 6,800 mJ/cm²
  • Transmission loss: 2,992 mJ/cm²
  • Process yield loss: 190 mJ/cm²
