What is roll-to-roll LED strip manufacturing?

DENO roll-to-roll LED strip manufacturing — also written reel-to-reel, and abbreviated R2R — uses an electroplated, non-die-cut FPCB kept as one continuous web through plating, etching, SMT assembly and packing. The circuit therefore carries no intermediate PCB splice joints inside its specified continuous length. Cutting interval, powered run length and feed arrangement remain model-specific.

What is an electroplated, non-die-cut FPCB?

A die-cut FPCB starts from rolled-annealed copper foil, typically 35 µm with 50 µm heavy variants, laminated to polyimide and mechanically punched. An electroplated non-die-cut FPCB grows the copper electrolytically onto the base film instead, so DENO's R2R circuits reach copper up to 105 µm or thicker with ±10 µm trace-width control. Compare the documented specifications rather than the process label alone.

What does a splice-free continuous FPCB actually mean?

DENO's electroplated, non-die-cut R2R FPCB has no intermediate PCB splice joints within the specified continuous circuit length. It is not a claim that the strip contains no soldered components, and it is separate from dot-free illumination, which is an optical property of pitch and diffusion. Cutting interval, run length and power-feed requirements remain model-specific.

Is a 50 m LED strip roll the same as a 50 m powered run?

No. The supplied reel length describes packaging; the maximum powered run length depends on the model's operating voltage, power per metre and feed arrangement. Reel formats are model-specific, so confirm both the available reel length and the required power-feed plan — including any mid-run injection — before you specify a long installation.

Which R2R LED strip suits SMD and SOB projects?

R2R SMD LED strip is the general-purpose choice for coves, shelves and architectural lines where discrete packages and standard cut units are appropriate. R2R SOB builds add a coated, dot-free luminous surface for exposed and close-viewing positions. Both use DENO's electroplated, non-die-cut FPCB; cutting interval, run length and power-feed requirements remain model-specific.

Can DENO manufacture a custom or OEM roll-to-roll LED strip?

Yes. As an LED strip and LED tape manufacturer running its own FPCB, SMT and extrusion lines, DENO develops custom and OEM/ODM roll-to-roll builds: board width, copper weight, LED pitch, cut interval, IP construction, reel format, connectors and packaging. Send the length, electrical specification, quantity and environment so feasibility and reel availability can be confirmed for your project.

Roll-to-Roll Long Reel LED Strip Light (#16774)

Every reel is produced on DENO's roll-to-roll line with 99.9% pure copper FPCB and ships CE, UL and RoHS compliant for architectural, retail and hospitality projects. OEM and ODM configurations of length, colour temperature and waterproofing are available on request. This model uses DENO's electroplated, non-die-cut R2R FPCB, with no intermediate PCB splice joints inside the specified continuous length. Cutting interval, rated run length and planned feed positions remain model-specific.

Description

Built on DENO's electroplated, non-die-cut R2R FPCB, this model has no intermediate PCB splice joints within its specified continuous length. Cutting interval, rated run length and feed positions remain model-specific.\nRoll-to-roll manufacturing removes the periodic board-to-board solder junctions found on sheet-to-sheet tape, leaving no intermediate PCB splice joints on the reel. Engineered with a slim 5mm 2oz copper PCB, this 24V LED strip light ensures effective thermal dissipation and steady electrical performance. Featuring 168 high-density 2835 SMD LEDs per meter with precise 35.714mm cutting increments, it delivers smooth dimmable illumination with a 120-degree beam angle. A single continuous SMT pass places every LED on the roll, supporting even light output along long uninterrupted runs. Optimized for retail and commercial displays, this constant voltage LED strip light is available for wholesale project supply and OEM manufacturing requirements.

High-Power LED Strip: Heat Dissipation & Aluminum Channel Guide

At up to 30W/m, 16774 is a high-power SMD LED strip. Above roughly 14.4W/m the tape can no longer shed its own heat through the FPC alone — an aluminum channel is part of the luminaire, not an accessory.

Why high-wattage strips need a heat sink

Aluminum conducts heat roughly 30× faster than the plastics, MDF or gypsum a strip is usually stuck to, so a bare high-power run traps heat under the tape.
LED lifetime (LM-80 / TM-21) is driven by solder-point temperature Tc. Keeping Tc inside the datasheet limit — DENO strips are rated Tc ≤ 75°C — is what preserves the rated L70 lifetime and colour stability.
Never run 14.4W/m or more coiled on the reel, inside a sealed plastic diffuser, or directly on wood, wallpaper or foam.

Sizing rule: FPC width vs channel inner width

Channel inner width ≥ FPC width + 2mm. This strip is 5mm wide, so it needs at least 7mm of inner width.
The 2mm clearance absorbs extrusion tolerance and lets the tape be seated or replaced without scraping the side walls or the wiring.
A frosted or opal PC cover then diffuses the higher lumen output into an even, dot-free line instead of visible hot spots.

Aluminum channels that fit this strip

Recommended LED Channels

Mount this LED strip in a DENO LED aluminum profile for heat dissipation, physical protection and diffused, dot-free output.

This strip is 5mm wide, so it needs a channel with at least 7mm inner width (5mm + 2mm clearance). Every profile below meets that.

Frequently Asked Questions

What are the key specifications of 16774?

16774: 2835, 168 LEDs/m, 24V, 5 PCB, 2oz copper FPCB, cuttable 6LEDs/35.714mm. Full photometric data, wiring diagrams and test reports are available in the downloads section of this page.

What makes the construction of this roll to roll LED strip different?

It is built as a roll to roll LED strip on 2oz copper FPCB with a cutting unit of 6LEDs/35.714mm and an LED pitch of 5.952mm, so it holds its electrical and mechanical performance where standard strips fail.

Can DENO customise this roll to roll LED strip for a project?

Yes. DENO manufactures the Roll-to-Roll SMD Strips series as an OEM and ODM supplier: reel length, colour temperature, CRI grade, PCB width, waterproofing and private labelling can all be specified. Request a quote for lead time and project pricing.

How long can this LED strip roll run in one continuous piece?

This model ships as a continuous roll-to-roll reel with no mid-reel solder joints, so custom single runs beyond the standard 5 m are available. Keep the run within a 3% voltage drop: lower power densities support up to 20 m single-end, higher densities need a both-ends or mid-feed connection. Use the DENO ProCalc voltage-drop tool to confirm the exact limit for your length.

Why choose a roll-to-roll strip over a standard 5 m LED strip reel?

The electroplated continuous FPCB keeps copper thickness uniform along the whole reel, so resistance stays low, brightness stays even end to end, and there are no pieced solder points that can fail during bending or long-run installation.
