Curing an assembly that’s narrower than the lamp head above it means paying for coverage the part never uses — and on a dedicated PCB panel line, that mismatch adds up fast.

A Flood Head Shaped for the Lane, Not Just the Part

The Incure CDM™ + L64 pairs the CDM™ 9-inch polypropylene belt conveyor with a 6″×4″ UV LED flood head sized specifically for the standard 4-inch PCB panel lane. Delivered as a complete system — conveyor chassis plus lamp head — it provides 1,900 mW/cm² at 385/395/405 nm (1,600 mW/cm² at 365 nm) at 2-inch working distance, PLC/RS-232/foot-switch integration, and greater than 20,000-hour LED service life, all at up to 4 inches maximum part width.

Full-Area Flood, No Beam Alignment Between Runs

Unlike the M-Series focused-beam configurations available on the same CDM™ platform — the M51 at 5″×1″ or the M62 at 6″×2″ — the L64 delivers UV simultaneously across its entire 6″×4″ curing footprint. Parts up to 4 inches wide cure in a single pass with no fixturing adjustment or beam-position setup required between product changeovers, which matters on a line running mixed panel sizes within that 4-inch envelope.

A Non-Square Footprint That Fits the Panel, Not Just the Belt

Standard PCB panel conveyors run 4-inch lane fixtures, and the L64’s 6″×4″ format is shaped for exactly that: the 6-inch illumination length along the belt-travel direction covers standard panel gap-to-gap spacing, while the 4-inch width bounds the lane precisely, irradiating the assembly without wasting dose on belt material or fixture hardware outside the panel edge. The wider L88 configuration, at 8″×8″, over-irradiates laterally on a 4-inch lane — the L64 is the deliberately sized alternative rather than a scaled-down version of it.

Confirming which flood footprint actually matches a given panel lane, before ordering the wider configuration by default, is worth a quick check. Email Us with your panel dimensions and Incure can confirm the right fit.

Same Peak Intensity, Right-Sized Coverage

The L64 delivers the identical 1,900 mW/cm² peak intensity at 2-inch working distance as the wider L88 configuration — the intensity isn’t reduced to fit the smaller footprint, only the coverage area is. Belt-speed dose control ranges from 4,750 to 38,000 mJ/cm² UVA depending on speed, with PLC, RS-232, and foot-switch integration available for process control — a real advantage over the arc-lamp configurations on the same conveyor platform, which offer belt speed as the only control option. LED service life exceeds 20,000 hours with typical intensity loss under 20% over that life, well beyond the roughly 1,000-hour rating of the mercury-arc alternatives.

Matching flood footprint, wavelength, and control integration to the actual panel geometry avoids over-specifying the lamp head. This LED head is one of several options on the Incure CDM™ UV Conveyor platform, and shares its array design with the standalone Incure L-Series™ UV LED Flood Lamps family. Confirm your team’s Incure Vison™ eyewear is rated for LED output at this intensity as well.

PLC Integration Changes the Line Design Conversation

Because the L64 offers PLC, RS-232, and foot-switch integration where the arc-lamp configurations on the same CDM™ chassis are limited to belt-speed adjustment, specifying the L64 opens up process interlocks that aren’t practical with the arc lineup — automatic lamp shutoff tied to a part-present sensor, cure-cycle logging for traceability, or integration into a broader line-control PLC that already governs upstream and downstream stations. For a line being designed with those integration goals in mind from the outset, that control difference is worth weighing alongside the flood-footprint sizing question.

Curing Envelope and Control Detail

Curing height on the CDM™ + L64 adjusts from 0.5 to 2.0 inches — a tighter, lower-profile range than the F-series arc configurations on the same conveyor platform, reflecting the LED array’s shorter effective working distance for peak intensity. Belt speed adjusts across the standard 1.5–12.0 ft/min range, and the system supports both timer and continuous operating modes, switchable depending on whether the line runs discrete parts or a continuous web. Wavelength — 365, 385, 395, or 405 nm — is factory-configured at the time of order based on the target adhesive’s photoinitiator absorption peak, so confirming the correct wavelength before ordering matters more than it would with a broadband arc lamp that covers multiple wavelengths simultaneously.

Why Peak Output Runs Higher at Longer Wavelengths

Peak intensity at 385/395/405 nm (1,900 mW/cm²) actually exceeds the 365 nm figure (1,600 mW/cm²) on the L64 array — a characteristic of LED die efficiency at these wavelengths rather than a design trade-off. For adhesive formulations with some flexibility in photoinitiator absorption peak, that efficiency difference is worth factoring into wavelength selection alongside the chemistry itself, since it directly affects available cure energy at a given belt speed.
