S-PM680 Touch Screen Solder Paste Mixer: Automated Paste Preparation for SMT and EMS Production
Sep 18, 2026

Solder paste is the most process-sensitive material on an SMT line, yet it is often mixed by hand with a spatula. The S-PM680 Touch Screen Solder Paste Mixer from Southern Machinery turns paste preparation into a controlled process step, with digital speed and time settings, selectable positive, negative and alternating rotation modes, intelligent diagnostics and interlocked safety. This guide covers what the machine does, the bridging and voiding defects that inconsistent manual mixing causes, where it fits in a complete SMT and THT line, how it compares with the S-SPM01, S-PM800 and S-SPW01, and the parameters buyers should confirm before specifying one.

SP-1200 Semi-Automatic Screen Printer by Southern Machinery: High-Precision Stencil Printing for Long LED Boards

The SP-1200 from Southern Machinery is a high-precision semi-automatic screen printer engineered for large-format PCBs up to 350 x 1200 mm — the long, narrow boards used in LED tube lights, linear lighting, and signage. A steel squeegee base driven by an SMC rail and Panasonic speed-control motor delivers steady, repeatable solder paste deposition across the full print area. Ideal for LED lamp SMT lines and low-to-mid-volume operations running oversized boards, the SP-1200 delivers consistent print quality without the capital cost of a fully automatic line. Read on for applications, selection parameters, and ROI guidance.

SME800 Auto Stencil Cleaning Machine: How Southern Machinery Optimizes Smart EMS Factory PCB Assembly
Aug 8, 2026

Stencil cleaning is one of the most underrated quality levers on an SMT line. The SME800 electric stencil cleaning machine from Southern Machinery automates the wash-rinse-dry cycle for solder paste and red-glue stencils, removing dried paste, flux residue and solder balls before they become print defects. With ultrasonic plus side-spray cleaning, DI water rinse and hot-air drying, the SME800 helps EMS factories lift first-pass yield and cut rework. This buyer's guide covers what the machine does, where it fits in the line, and what to evaluate before purchase.
