AVI S-D330 Online Wave Solder Appearance Checking Machine by Southern Machinery

Missing parts, reversed polarity, and soldering defects that escape the wave outfeed can cause rework and delayed shipments. The S-D330 inspects PCBA inline before and after the wave, catching faults before final QC.

What is this machine used for?

The S-D330 is an inline Automated Visual Inspection (AVI) station that checks THT and SMT quality around the wave soldering process.

• Catches insertion faults: wrong or missing components, wrong placement, reversed polarity
• Detects SMT faults: leakage, chip faults, polarity reversal, excursion
• Captures whole-board images with a 14 MP full-color camera
• Operates inline via belt or bridge-joint conveyor; supports SPC export to Excel/TXT

How the S-D330 fits into a complete PCB assembly line

1. After wave soldering, boards enter via bridge-joint or belt conveyor.
2. The system captures a full-board second shot and processes it synchronously.
3. OK boards continue downstream; NG boards are flagged for rework with SPC records.

Key selection parameters for buyers

• Compare PCB size against the standard 330 x 250 mm range (larger sizes customizable)
• Define the defect set: insertion faults, SMT faults, or both
• Evaluate programming mode and Excel/TXT reporting needs

ROI perspective

A post-wave AVI replaces repetitive manual QC at the outfeed and catches polarity, leakage, and wrong-component issues before functional test. Southern Machinery provides ROI modeling case by case.

FAQ

How is the S-D330 different from a THT insertion AOI?

The SVL501T AOI checks THT insertion; the S-D330 checks PCBA before and after the wave for both insertion and SMT quality.

What defects can it detect?

Wrong or missing components, wrong placements, reversed polarity, SMT leakage, chip faults, and excursion.

What PCB sizes can it inspect?

330 x 250 mm standard; larger sizes are customizable.

Can it run inline?

Yes - bridge-joint or belt conveyor options enable inline use.
