S-MUL350 Mini PCB Unloader by Southern Machinery
Manual PCB unloading at the end of the line ties up an operator and consumes valuable floor space. Southern Machinery's S-MUL350 automates board take-off in a compact 700x650x1400 mm footprint.
What is this machine used for?
This is a small-footprint SMT unloader designed for PCB take-off on SMT and FPC lines. It conveys boards upward, automatically corrects tilted PCBs, and requires no magazine – operators simply remove boards from the track.
- Semi-automatic unloading for SMT, FPC, and mixed lines
- Automatic PCB tilt correction keeps boards aligned

How the product fits into a complete PCB assembly line
- Line-end take-off after reflow, wave soldering, or AOI
- Feeds test, inspection, or packing stations at 900 mm height
- SMEMA-style signaling handshakes with the upstream machine
- Buffer positions smooth flow between fast and manual stations
- Compact layout suits short lines where a magazine unloader cannot fit
Key selection parameters for buyers
- Confirm board size and weight against the 445 x 350 mm / 2 kg limits
- Check transport height against the upstream conveyor (900 mm +/- 20 mm)
- Clarify power (110 VAC or 220 VAC) and unload staffing
ROI perspective
Replacing manual board removal with the S-MUL350 frees one operator per shift for value-added work and clears a line-end bottleneck. ROI modeling is provided case-by-case – no generic guarantees.
