S-D602 LED Depaneler: V-Cut Buyer Guide

The S-D602 LED depaneler from Southern Machinery is a V-cut PCB separation machine with six cutting knives in three pairs, built for aluminum PCB, FR-4, LED PCB and PCBA boards from 0.5 to 3.0 mm thick. It follows the microgroove in three stages instead of one pass. Final suitability should be confirmed against your board sample.

Why does the blade matter less than the cut path?

Most teams shopping for an LED PCB depaneler compare blade steel first. Yet when a V-cut board is separated hundreds of times a shift, the cutting path and board support determine how stable the result is.

The hidden problem with repeat V-cut separation

You already know the groove is right. What concerns you is the breakout: will the next board, the next long LED strip, the next batch behave the same way? The supplied specification describes smooth separation with reduced risk of board, component and solder-joint defects after breakout. That is the right target to measure any machine against.

What is a repeatable way to choose an LED depaneler?

Use this four-check framework before you request a quote.

1. Material: list the board type. The S-D602 source lists aluminum-based board, FR-4, glass fibre board, PCB and PCBA.
2. Thickness: the listed cutting thickness is 0.5-3.0 mm.
3. Clearance: the distance between parts and the microgroove must be above 1 mm; side width is unlimited as listed.
4. Output: state your target pieces per minute. The source lists 2.5 pcs per minute for a 1200 mm PCB with 10 PCB boards, a supplied condition only. Confirm capacity against your own layout and final configuration.

How does the S-D602 put that framework to work?

The machine is described as a controlled three-stage cutting path. Three pairs of blades divide the cutting action and help locate the V-cut consistently.

Align, cut, release

• Align: position the PCB so the microgroove meets the blade path.
• Cut: three pairs of knives engage the groove in sequence.
• Release: the angled platform arrangement lets the processed board fall away from the working surface.

Blades, platform and calibration

Blades are specified as Japanese SKD-11 high-speed steel. A 2400 mm processing platform is listed for long boards. The supplied data also describes front and rear blade calibration with a double-frequency laser interferometry instrument.

Which specifications should you compare?

| Item | S-D602 as listed in source |

|---|---|

| Name | LED strip Aluminum PCB Depaneling Cutting Machine |

| Voltage | 220V / 110V, 50Hz / 60Hz |

| Cutting thickness | 0.5-3.0 mm |

| Maximum cutting length | Unlimited, as listed |

| Processing platform | 2400 mm, as listed |

| Machine size | 300 x 230 x 220 mm |

| Weight | About 36 kg |

| Working temperature | 10 to 35 C |

| Storage temperature | -20 to 50 C |

| Knives | 6 (three pairs), SKD-11 |

Note: the source lists both a 2400 mm platform and a 300 x 230 x 220 mm machine size. Confirm the final machine and platform arrangement for your project. \"Unlimited\" length is the supplied value; confirm it with the final configuration.

How does it fit a complete PCB assembly line?

A depaneler sits after assembly and inspection, where panels become individual boards. Plan it alongside upstream board handling systems, 3D SPI and AOI inspection, and THT equipment or wave soldering for mixed-technology boards. Southern Machinery, founded in 2011 in Shenzhen and serving 237+ global customers, supplies SMT, THT, wave soldering, board handling and inspection solutions with global service, spare parts support and professional training.

How should you estimate the payback?

ROI formula (example only, depending on configuration and subject to final technical confirmation):

Annual value = (manual separation hours saved x labor rate) + (scrap avoided x board cost) - annual running cost

Worked example with placeholder inputs: 2 hours saved per day x 250 days x 10 per hour = 5,000 saved labor value per year, before any scrap effect. Replace every input with your own data. This is not a guaranteed return.

FAQ

What board types can the S-D602 process? The source lists V-cut PCB, aluminum PCB, FR-4, LED PCB, PCBA and glass fibre board.

What is the blade arrangement? Three pairs of blades, six knives in total, in a staged cutting path.

Which voltage is supported? 220V or 110V, 50Hz or 60Hz; confirm the final electrical configuration for your market.

What should I send with an RFQ? Board material, thickness, V-cut drawing, longest board length, component-to-groove distance, destination voltage and target pieces per minute.

Can my board be tested? The source says to include a board sample or clear drawings so the cutting path and application limit can be reviewed.
