UV Adhesive Cure Dose at 90% substrate and fixture uv transmission: a worked example

This scenario runs the uv adhesive cure dose calculation on the strong side: 90% substrate and fixture uv transmission, with every other input held at its documented default. an applications engineer needs to check UV dose for a light-curable adhesive process

The inputs for this scenario

  • UV intensity at bond line: 850 mW/cm² (unchanged)
  • Exposure time under lamp: 8 s (unchanged)
  • Substrate/fixture UV transmission: 90 % (raised for this scenario; the documented default is 78)
  • Cure process first-pass yield: 95 % (unchanged)

Working through the calculation

  • Applying the documented formula (Theoretical UV dose = UV intensity at bond line × exposure time) to the inputs above produces each figure below.
  • At this operating point the engine returns 5,814 mJ/cm² for effective uv cure dose, the number this scenario is built around.
  • At this operating point the engine returns 6,800 mJ/cm² for theoretical uv dose.
  • At this operating point the engine returns 680 mJ/cm² for transmission loss.
  • At this operating point the engine returns 306 mJ/cm² for process yield loss.

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 15.38% above the baseline at 5,814 mJ/cm².
  • Use it when qualifying a new light-cure adhesive, validating a conveyor or spot-cure recipe, or troubleshooting bonds that test weak despite an apparently adequate lamp setting. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
