S-D502 LED Tube Separator — Long-Platform V-Cut PCB Depaneling for LED Boards

A 1.2-meter LED strip snapped by hand at the V-groove rarely breaks where it should. The panel flexes, the remaining web cracks past the score line, and a row of LEDs lifts off the pad — quietly, on a board that already passed reflow. The S-D502 LED Tube Separator is built for exactly this job: a long-platform, motor-driven V-cut separator that singulates pre-scored LED boards and long panels up to 1200 mm in a single pass.

The cost you haven't named: long-panel hand breaking

Long boards punish manual depaneling more than short ones, yet most lines still treat the break as a bench task nobody measures.

Edge cracking on flexible webs. Hand-breaking a 1200 mm panel bends it across its whole length; the V-score propagates past the groove and micro-cracks the FR4 or aluminum substrate under the components.
Component stress near the cut. LEDs, connectors, and capacitors close to the score line take shear load during a manual snap, causing intermittent opens that fail only under thermal cycling at the customer.
Dust and residue at the bench. Hand tools and sheared edges throw glass-fiber dust into the operator's breathing zone and onto nearby placements, a problem a sealed motor-driven blade largely removes.
Throughput ceilings. A bench operator breaks long panels slowly and inconsistently; the depaneling station becomes the bottleneck right after a fast reflow oven.

The Four-Point Long-Board Depaneling Audit

Before specifying any separator for LED or long-panel work, frame the purchase as a repeatable audit rather than a one-off buy. Call it the Four-Point Long-Board Depaneling Audit.

1. Measure the longest board. Record the maximum panel length you must singulate, including tube strips and any future wider product. That single number decides whether a 360 mm, 1000 mm, or 1200 mm platform is the right base.

2. Score the web geometry. Capture the V-groove depth, remaining thickness (0.25–2.0 mm is typical), and board thickness (0.2–5.0 mm). This sets the blade alignment tolerance the machine must hold to avoid cracking.

3. Count the dust-exposed steps. Tally how many boards pass a person before cleaning, and where fiberglass dust lands. The audit shows whether a motor-driven, low-residue cut is worth the floor space.

4. Set the clean-break target. Define acceptance as zero web cracking past the score, burr-free edges, and a consistent cycle. That statement becomes your incoming inspection test at delivery.

The vehicle: S-D502 LED Tube Separator

The audit above maps directly onto how the S-D502 is deployed in an LED or EMS line.

Measure the longest board → 1200 mm platform. The S-D502 handles LED tube strips and long panels up to 1200 mm in a single pass, against sister models S-D500 (360 mm) and S-D501 (1000 mm) for shorter work.
Score the web geometry → precise blade alignment. Upper and lower circular blades align to the V-groove with manual adjustment, holding the cut within the scored web so the remaining substrate stays intact.
Count the dust-exposed steps → motor-driven low-residue cut. Motor-driven circular blades produce minimal dust and residue compared with hand shearing, keeping the operator and nearby placements cleaner.
Set the clean-break target → adjustable speed control. Cutting speed is manually adjustable across 80, 120, 200, and 500 mm/s, letting the operator match feed rate to board thickness and component density for a consistent break.

Specification note: exact cutting length, blade alignment range, voltage option, and lead time should be confirmed at quotation, because they depend on your board mix, V-groove depth, and local supply spec rather than a single factory default.

The loop: re-audit every product change

Long-panel programs change more often than the separator does. Build a loop: every time a new LED tube or long panel enters the line, repeat the Four-Point Long-Board Depaneling Audit, re-check the V-groove depth against the blade alignment, and review the scrap count at the depaneling station with your line lead. If a board family pushes past 1200 mm or below 0.2 mm thickness, re-specify before ramping. Treat the audit as a living document — the loop is what keeps the S-D502 cutting clean instead of quietly reintroducing the edge cracks you bought it to remove.

We will return a depaneling review confirming whether the S-D502 (1200 mm), S-D501 (1000 mm), or a shorter model fits, what speed to set, and what to confirm at quotation.

FAQ

What board lengths does the S-D502 handle?

It singulates pre-scored LED strips, tube boards, and long panels up to 1200 mm in a single pass. Shorter sister models S-D500 (360 mm) and S-D501 (1000 mm) cover smaller work.

How does it reduce edge cracking versus hand breaking?

Upper and lower circular blades align to the V-groove and cut along the scored web, so the remaining substrate is not bent across its length the way it is during a manual snap.

What blade material is used?

Blades are made by a Taiwanese factory using Japanese high-speed steel, supplied for low-residue cutting and re-sharpening over the machine's service life.

Can the cutting speed be changed?

Yes. Speed is manually adjustable across 80, 120, 200, and 500 mm/s so the operator can match feed rate to board thickness and component density.

Which voltage does it run on?

Standard working voltage is 230 V / 50 Hz, with a 110 V / 60 Hz option available. Exact configuration is confirmed at quotation.
