L33 — UV LED Flood Curing Lamp, 3″ × 3″ Irradiation Area
Incure L33 is the step up from the L22 — 2.25× the curing area at the same 3,100 mW/cm² output across a 3″ × 3″ zone. Where the L22 covers a 2-inch bond area in one pass, the L33 reaches the 3-inch span: full conformal coating sections, multi-row SMT assemblies, or gasket rings too wide for the L22 to cover without repositioning. Still paired with the same C131C, C131D, and C141C chambers as the L11 and L22.
2.25× the Curing Area of the L22 — No Repositioning for 3-Inch Assemblies
The L33 expands from the L22's 4 sq. in. to 9 sq. in. — the same irradiance, a larger zone. Assemblies that span 3 inches in one or both dimensions no longer require two passes with the L22 or a fixture repositioning step. The 3″ × 3″ array covers one full substrate section per trigger cycle: a single PCB zone, an entire bond-line row, or a square adhesive pattern in one uninterrupted exposure.
Cures Full Conformal Coating Sections and Gasket Rings in One Pass
Conformal coating sections, dome coating areas, and perimeter gasket rings frequently span the 2–3 inch range. The L22 requires two overlapping exposures or a repositioning jig for these geometries; the L33 covers the full zone in one cycle. Consistent single-pass exposure eliminates the dose variation introduced by overlap zones in multi-pass curing workflows.

Irradiance values measured at 100% output intensity at the specified working distance. Peak intensity at 385/395/405 nm configurations exceeds 365 nm output for the L33 array — this is a characteristic of the LED die efficiency at these wavelengths. Static uniformity measured as minimum/maximum intensity ratio across the irradiation area. LED lifespan rated at greater than 20,000 operating hours under standard conditions; no recalibration or bulb replacement required during normal service life.
