SH8650 3D SPI Machine for Solder Paste Inspection by Southern Machinery

SPI (Solder Paste Inspection) after stencil printing is the earliest quality gate on an SMT line. The SH8650 3D SPI from Southern Machinery measures solder paste deposits in 3D before placement, catching defects while they are still cheap to fix. For EMS and ODM factories, it protects first-pass yield before reflow.

What is the SH8650 used for?

3D inspection of solder paste deposits on PCBs after stencil printing
Detects insufficient/excess paste, bridging risk, offset and volume deviation before placement
Handles PCBs up to 510mm x 460mm
Compatible with both lead-free and leaded solder paste
Suited to EMS, ODM, automotive, medical and general electronics lines
