Complete EMS cleaning line — PCBA in-line & batch washers, stencil and screen cleaners, nozzle, pallet, reflow-cooler and bare-board systems — engineered around water-based chemistry, closed-loop filtration and your SMEMA conveyor.
Every photo on this site is a real Southern Machinery installation photos from the ph.smthelp.com image archive — no renders.
Like the best cleaning-equipment sites in the industry, we organize by task first, machine second — because your quality engineer thinks in residues, not in models.
Rosin, no-clean and water-soluble flux residues plus solder balls drive ion contamination and under-package voids. Inline (SME-6300) or batch (SME5600D / AC510) aqueous wash–rinse–dry cells.
PCBA cleaning systems →Paste residue packed in fine-pitch apertures = bridging and insufficient deposits. Pneumatic S-1688 or electric SME800 / BC320 regain 100% aperture flow.
Stencil & screen cleaning →Coated or clogged nozzle tips cause mis-picks and throw errors. S-6200 / SCM24 clean nozzles from 01005 to Ø2.0 mm in a 24-hole jig.
Nozzle cleaning →Flux-smothered carriers destroy seat accuracy and add heat resistance. SME5200 / SME5300 rotate-spray cabinets clean pallets, conformal carriers and trays.
Fixture & pallet cleaning →Scrubbing coolers by hand? The SME5500 batch washer degreases fan modules and cooler fins without disassembly drama.
See SME5500 / BC230 →Dust, adhesive roll residue, fingerprints: SQC brush + vacuum + static-elimination units, plus ultrasonic tanks and your own 18 MΩ DI water plant.
Bare PCB & utilities →Ion contamination and residue-induced leakage pass AOI and fail the customer's reliability audit — field returns cost far more than a washer.
Clogged apertures from yesterday's paste print silently starve today's QFPs. Manual wiping pushes paste into the underside of the foil.
A coated tip changes pick force. Mounters stop, the line supervisor grabs alcohol wipes, and nobody logs the root cause.
Open-solvent cleaning is a fire, health and customs issue. Aqueous chemistry in a sealed stainless cabinet removes all three headaches.
Batch rinsing with a leaking conductivity window lets ionic films re-deposit. Inline DI plants keep rinse water at 0–18 MΩ where it belongs.
Automotive and medical EMS customers ask for cleaning process records. Documented cycles, filters and validation reports answer before they ask twice.
Mix cabinets and in-line cells, share chemistry and filtration know-how, and get one point of contact for spares and service.
