Advanced assemblies leave little room for cure variation. The Incure F900P is a programmable UV flood lamp that lets an engineer define an exposure profile, store it as a recipe, and reproduce it exactly on every part, giving demanding electronics, optical, and coating processes a documented, repeatable ultraviolet cure.
What the F900P Is
The F900P is the programmable member of Incure’s F-Series arc flood lamp line. Where a standard flood lamp offers on-off operation, the F900P adds set-point intensity control, timed and multi-stage exposures, and stored recipes selected by part number rather than re-entered by hand.
Why Programmable Control Matters
Light-curable chemistry has a working dose window. Below it, the film stays under-crosslinked and tacky; above it, the polymer can embrittle or discolor. A saved profile keeps every part inside that window across shifts and across duplicate stations. For assemblies that pass through audits or process-capability review, the F900P’s ability to log commanded and measured output turns cure into a traceable step instead of an operator decision.
Multi-Stage Profiles Reduce Stress
A single hard exposure can lock in shrinkage stress at the bond line, especially in thicker sections or across a coefficient of thermal expansion mismatch. A ramp-hold-taper profile lets the adhesive gel gradually, relax, and then reach full conversion, which lowers residual stress and the risk of later delamination.
Building an F900P Recipe
- Take the target dose in mJ/cm² from the material datasheet at its specified wavelength.
- Measure delivered irradiance at the working distance with a band-correct radiometer.
- Set exposure time or profile stages to reach the target dose.
- Confirm cure with hardness, solvent rub, or pull testing on sample parts.
- Lock the recipe, document it, and re-verify irradiance on a schedule as the lamp ages.
Where Staged Profiles Earn Their Keep
Not every cure needs a multi-stage profile. A thin, low-shrinkage coating on a stable substrate cures fine with a single flat exposure. Staging pays off in three situations:
- Thick bond lines: A gentle initial exposure lets the resin gel and vent before full-intensity cure, reducing entrapped stress and voids.
- Dissimilar substrates: Where the bond spans a large expansion mismatch, a slower approach to full conversion lets the joint relax as it stiffens.
- Appearance-critical coatings: A tapered final stage reduces surface haze and orange peel that a hard cutoff can lock in.
Logging and Traceability
The F900P can record commanded and measured output for each cycle. Retaining that log turns a cure into a defensible process step: if a batch is later questioned, the record shows every part received its specified dose. The same data feeds a periodic capability review, comparing measured cure results against the acceptance window to confirm the process still has margin.
Integration Notes
Decide early whether the lamp runs standalone with a footswitch or handshakes with a line controller. PLC integration lets the cure station signal ready, accept a part-present trigger, run the correct recipe by part number, and report a fault if measured output falls outside tolerance. Wiring this in at install is far cheaper than retrofitting it later.

Applications
The F900P suits electronics conformal coating and encapsulation, optical component bonding where stress control is critical, precision coating lines with tight appearance limits, and specialty adhesive assembly. For very large fields or cool-running LED cure, the L-Series UV LED flood lamps are the companion option.
Selection and Integration
- Wavelength matched to the photoinitiator, commonly 365, 385, or 405 nm equivalents for arc output.
- Power headroom above the target dose so an aging lamp still qualifies.
- Profile capability: confirm the number of stages and ramp control your process needs.
- Field size and uniformity covering the largest cured area within roughly 10–15 percent edge falloff.
- Line interface: footswitch, PLC handshake, or controller integration.
Maintenance
Clean the emitting window and reflector on a fixed interval, replace the bulb at its rated hours rather than at first defect, and keep the radiometer calibrated so logged output reflects real delivered energy.
Frequently Asked Questions
Q: When does a staged profile beat a single flat exposure?
A: On thick bond lines, across a large expansion mismatch between substrates, and on appearance-critical coatings. A thin, low-shrinkage coating on a stable substrate does not need staging.
Q: Can the F900P integrate with a line controller?
A: Yes. It can accept a part-present trigger, run the correct recipe by part number, and report a fault if measured output falls outside tolerance. Wire this in at install rather than retrofitting later.
Q: How is the cure recipe validated?
A: Run 30 or more parts on a locked profile, measure cure by hardness or pull strength, and confirm the results stay inside the acceptance window with margin. Retain the per-cycle output log as the ongoing record.
