SVL501T THT Dual Sided AOI by Southern Machinery

The SVL501T THT dual sided AOI (AVI) checks component insertion before and after wave soldering, catching missing parts, polarity errors and solder defects early.

What is this machine used for?

In-line AOI (AVI) for THT/DIP assembly, checking THT insertion before or after wave soldering. Typical uses:

• Insertion lines with manual or auto THT parts
• Post-wave solder bridge and joint verification
• Polarity check on caps, diodes, ICs, connectors
• Optional press-fit and SMD checks on mixed boards

Verified inspection capabilities (product catalog)

| Inspection | Capability (product page) |

|---|---|

| Component presence | Missing / wrong component, color and band inspection |

| Polarity | All components with text incl. ICs (character verification), connectors |

| Solder quality | Solder bridge and solder joint |

| Press-fit (opt.) | Down to 0.5x0.5 mm2; lifted components, pin shifting (top side) |

| SMD (opt.) | Down to 0603, polarity, bridge, missing down to 0402 |

| OCR / surface / laser (opt.) | Label OCR; surface and laser height down to 0.5x0.5 mm2 |

Confirm parameters and optional modules during quotation.

How it fits into a complete PCB assembly line

1. Component insertion (manual or auto) produces the THT board
2. SVL501T inspects insertion quality before wave soldering
3. Wave soldering completes the solder joints
4. Second pass verifies solder bridge and joint quality
5. Optional press-fit and SMD checks cover mixed boards

Key selection parameters

• PCB dimensions, conveyor width, SMEMA compatibility
• Component mix: THT, press-fit, SMD on the board
• Optional modules and MES data output

ROI perspective

Manual THT inspection is slow and inconsistent. In-line AOI removes the bottleneck between insertion and wave soldering, cuts rework and escapes. ROI modeling is case-by-case.

FAQ

Is it used before or after wave soldering?

Both - before wave soldering for insertion check, after for solder quality, in-line.

Does it detect polarity errors?

Yes - all components with text incl. ICs (character verification) and connectors with polarity requirements.

Can it inspect SMD components?

Optionally - SMD to 0603, missing to 0402, plus polarity and bridge.
