Wave Soldering

SMT pallets and fixtures carry flux, grease and dust onto your PCBs. Southern Machinery's SME-5200 Aqueous Pallet Cleaning System automates wash, rinse and dry in one machine: a rotating 1 m cleaning basket, 80 L fluid and rinse tanks, three-stage filtration, and PLC control that runs the whole cycle with one push of the start key. Built in Shenzhen and trusted by 237+ global customers, the platform is proven in a Schneider factory performance test. This guide covers what it is used for, typical applications, how it fits a complete SMT/THT line, key selection parameters and the ROI perspective for EMS factories.

The fully automatic selective wave soldering machine from Southern Machinery brings fixture-free, programmable THT soldering to high-mix EMS and electronics factories. Boards are programmed directly in software and soldered with spot, drag, continuous spot or continuous drag modes, so changeover is a programming step instead of a tooling change. Reference configurations offer 100 mm and 200 mm preheat zones, automatic solder feed and non-standard customization, with a 5.0/5.0 rating and 24-hour continuous operation on the reference listing. Founded in Shenzhen in 2011, Southern Machinery supports 237+ customers with complete SMT/THT, wave soldering, board handling and inspection line solutions, including training, spare parts and engineering support. Send your board size and joint count for a configuration within 24 hours.

Boards that lift, shift or sag in the solder wave create bridges and open joints that cost rework. A wave soldering pressure-plate fixture from Southern Machinery holds PCBs flat and stable through the wave, using high-hardness synthetic stone that resists heat and flux corrosion. Each fixture is customized by sample or drawing, with a reference 48-hour prototype before production, so high-mix EMS and electronics factories can ramp faster and keep wave soldering quality consistent. Learn how the fixture fits a complete SMT/THT line and what to specify when requesting a quote.

Every misprint, tombstone and bridge that traces back to unstable tooling quietly taxes an SMT or THT line. Southern Machinery designs custom fixtures, carriers and jigs from your board sample or drawing - high-precision spring-type printing fixtures, reflow carriers, wave soldering pressure-plate carriers, carrier clips, calibration jigs and pallet/fixture cleaning support. Board-specific tooling keeps PCBs flat, aligned and repeatable through solder paste printing, reflow, wave soldering and auto-insertion, cutting rework, stabilizing quality and simplifying line integration. With a 48-hour prototyping reference, aluminum and high-hardness synthetic stone materials, and factory-direct supply from Shenzhen since 2011, the program is built for high-mix EMS, automotive, medical and industrial electronics.

The S-100B desktop selective soldering machine from Southern Machinery brings fixture-free, programmable THT soldering to high-mix, low-volume EMS lines, labs and prototyping. A 3-axis XYZ robot with ±0.05 mm positioning, ST-6 jet fluxing, N2 preheat and an 8 kg titanium solder pot apply solder only where the program says — protecting temperature-sensitive components and eliminating pallet tooling. Board changeover becomes a software step, not a fixture build. Southern Machinery, founded in Shenzhen in 2011, supports 237+ global customers with complete SMT/THT, wave soldering, board handling and inspection line solutions, including training, spare parts and engineering support. Send sample boards for a trial weld and configuration within 24 hours.

Unstable PCB transport is a hidden cause of bridging, skips and icicles in wave soldering. Southern Machinery supplies precision titanium claws and fingers that hold boards steady through fluxing, preheating, soldering and cooling - reducing rework, protecting throughput and extending part life. With 200+ stocked models for Jintuo, Nitto, Vitronics Soltec, ERSA, Kaitai and more, plus exact replication from sample or drawing, teams can replace OEM fingers without production delays. This guide covers geometry selection, machine compatibility, line integration and how to match the right claw to your wave solder conveyor.
