Automate Post-Wave Lead Trimming: S-320AT Inline Auto Lead Cutter by Southern Machinery
Manual lead trimming after wave soldering is hard to staff, slow, and inconsistent. The S-320AT inline auto lead cutter takes that step out of operators' hands — automating the entire process.
What is this machine used for?
The S-320AT is an inline automatic lead cutter designed for through-hole PCBA finishing. It trims leads one by one along a pre-programmed path, vacuums the waste, and automatically recycles the pins.
- Post-wave soldering lead trimming for THT boards up to 250 × 320 mm
- Ideal for power supplies, appliances, LED lighting, automotive, and industrial PCBA
- Perfect for production lines facing recruitment challenges and rising labor costs

How it fits into a complete PCB assembly line
- THT inserters (S-3010B, S-70LD, S-7020) place radial, axial, and odd-form components.
- The board passes through wave soldering (S-WS450, S-WS350B).
- The S-320AT inline station follows the wave, trimming leads along a programmed path at over 7,200 points/hr.
- Trimmed pins are vacuumed away and recycled automatically.
- Finished boards then move to inspection (AVI/AOI).
ROI perspective
The S-320AT replaces 3–5 soldering and trimming workers per shift with one programmable station — directly addressing the key pain points: recruitment difficulty, low efficiency, inconsistent quality, and high labor cost. Per-point trim programming removes hand-trimming variance, and the tungsten cutter provides long service life. ROI modeling is case-specific, so we do not offer generic guarantees.
