MEK ISO-Spector S3 – 3D Solder Paste Inspection System
Proftek supplies the MEK ISO-Spector S3 3D Solder Paste Inspection (SPI) system to SMT manufacturers across Australia and New Zealand. By accurately measuring solder paste volume, height, area, and offset immediately after printing, the ISO-Spector S3 eliminates paste printing defects before they reach the reflow oven. Industry data shows that 60 to 70 per cent of SMT assembly defects originate at the solder paste printing stage, making SPI the single most impactful quality investment for any SMT production line.

Industry research consistently shows that 60 to 70 per cent of all SMT assembly defects originate at the solder paste printing stage. Insufficient paste volume causes cold joints and opens, while excess paste leads to bridging and shorts. The MEK ISO-Spector S3 eliminates these risks by catching printing errors at the source — before boards enter the reflow oven, where defects become costly to rework.
The ISO-Spector S3 integrates with your screen printer via closed-loop feedback, automatically detecting drift in print quality and triggering corrective adjustments in real time. Paired with the MEK Catch traceability platform, every SPI result is stored against the board serial number, providing a complete print quality history for process optimisation and compliance reporting.
