S-9300 3D SPI by Southern Machinery — Inline Solder Paste Inspection

Roughly 74% of PCB assembly defects begin at solder paste printing. The S-9300 3D SPI inspects deposits in 3D inline — before placement — on 0201/01005, QFP/PLCC/BGA, automotive and medical boards.

What is this machine used for?

The S-9300 is an inline 3D Solder Paste Inspection (SPI) system for SMT lines. After printing, it flags four defect families: offset (paste outside the process area), insufficient paste, excess paste and bridging.

Verified specifications from the product catalog

| Parameter | S-9300 3D SPI |

|---|---|

| Vision and speed | Colour vector boundary measurement; German 5 MP CCD, telecentric lens; 12 µm (8.8/15 µm option); FOV 29.5 × 24.7 mm; 0.28 s per FOV |

| PCB envelope | 50 × 50 to 415 × 355 mm; 0.6–5.0 mm; under 5 kg; warpage under 3 mm; component height above 10 mm / below 30 mm |

| Structure | Cast iron frame, C4 ball screw, P-class slide, AC servo; ±3 µm repeatability |

| Flow and PC | Left-in right-out standard (reverse optional); online PC, visual programming, production monitoring |

| Utilities | 0.5 ± 0.1 MPa at 5 L/min; 220 V 50 Hz, 1000 VA; 620 × 1310 × 1500 mm; 950 kg |

Optional 200 mm track extension and UPS. Please confirm parameters at quotation.

How the S-9300 fits into a complete SMT line

Sits between the printer and the mounter, inspecting boards inline
BAD-MARK output warns the mounter before bad paste reaches placement
SPI feedback returns to the printer and mounter; SPI-SPC and multi-line quality data consolidate on a server

ROI perspective

Catching a fault at printing costs about $0.5, versus $5 after placement and $35 after rework. According to the catalog, a roughly $50k SPI model returns $24k (QC, 2 shifts) + $15k (rework) + $5k (printer optimisation) + $6k (SPC/audit) a year — about a one-year payback.
