Southern Machinery S-V8000 Vacuum Reflow Oven - Void-Free Soldering for High-Reliability PCBA

The S-V8000 is Southern Machinery's inline vacuum reflow oven for programs where solder-joint voids limit quality: the vacuum stage pulls entrained gas from the molten joint, reducing the solder void rate to 3% or less.

What the S-V8000 Does

The S-V series is designed for R&D, process development, and high-volume production. Applications listed on the product page include IGBT packaging, LED eutectic soldering, laser diodes, hybrid ICs, MEMS, and vacuum packaging.

• 8/8 preheat zones across a 3000 mm tunnel, plus 2/2 cooling zones
• One vacuum zone at 10–100 Pa, with adjustable pumping speed up to 40 m³/h
• Nitrogen consumption of 20–30 m³/h at 500–800 ppm oxygen
• Vacuum module independently controlled and closable for standard air/N₂ reflow
• Touchscreen + Siemens PLC, MODBUS communication, and UPS power-off protection

Line Integration

A conveyorized inline machine with 0.2 mm width adjustment, it fits the reflow position in an SMT line. Southern Machinery also supplies pick-and-place, wave and selective soldering, board handling, depaneling, and inspection equipment.

ROI and Cost Position

Removing voids before X-ray inspection reduces rework and scrap on power and package assemblies. The vacuum stage can also be switched off for standard products, so one oven covers both process classes.

FAQ

Is the S-V8000 a reflow oven or a vacuum chamber?

Both: it is an inline 8-zone reflow oven with one integrated 10–100 Pa vacuum zone.

Which packages benefit most?

IGBT power devices, LED eutectic and flip-chip packages, laser diodes, MEMS, and vacuum packages.

Can it run normal lead-free reflow?

Yes—the vacuum section is independently controlled and can be closed.

What utilities are needed?

380 V 3-phase 5-wire; exhaust 110 m³/min over 2 × φ180 mm; external water cooling.
