AVI S-D330 Inline Wave Solder Inspection by Southern Machinery

An inline AVI is only as good as its decision logic. Here is how Southern Machinery's S-D330 inspects PCBA around the wave solder process.

What the S-D330 checks, and how it decides

The S-D330 is an inline AVI station that inspects PCBA before and after wave soldering. Its classification methods are characteristic extraction, draw colour, OCV and graph comparison; it detects insertion faults (fault component, leakage, polarity reverse) and SMT faults (leakage, chip fault, polarity reverse, excursion).

Programming is manual or by automatic match; the camera reads 1D/2D codes under LED white light.

Where it sits on the line

1. Runs in the feeder line or on the belt for online inspection.
2. Bridge-joint line or belt conveyor options make it inline-ready.
3. OK boards continue down the line; flagged boards exit with their SPC record.

Key selection parameters

• Panel size against the 330 x 250 mm standard range (larger ranges are a customization).
• Defect set: insertion quality, SMT quality, or both.

ROI perspective

Rework caught at the wave outfeed costs less than rework at functional test. The S-D330 takes over repetitive manual visual QC and logs every board automatically; Southern Machinery models ROI case by case.

FAQ

What does OCV mean here?

Optical character verification - reading component markings to confirm the right part.

Manual or automatic match programming?

Both are supported; automatic match runs against a reference.

Can it inspect larger panels?

Yes - larger ranges are a customization.

How does it differ from the SVL501T AOI?

The SVL501T checks THT insertion; the S-D330 checks PCBA around the wave.
