ProfTek supplies the complete MEK 3D AOI (Automated Optical Inspection) range for SMT, through-hole, and conformal coating PCB inspection. From entry-level inline systems through to high-speed selective 3D AOI for high-mix manufacturing, the MEK range covers every Australian and New Zealand electronics production scale — from prototype to high-volume.
2D AOI catches missing components and gross placement errors, but cannot detect lifted leads, insufficient solder, head-in-pillow defects, or component tilt. 3D AOI uses structured light or laser triangulation to measure exact component height and orientation — catching defects that 2D systems pass and that would otherwise fail in-circuit test or, worse, field deployment. For Australian electronics manufacturers serving aerospace, medical, automotive, and defence markets, 3D AOI inspection is increasingly a customer tender requirement. ProfTek can match the MEK system to your line speed, mix complexity, and CAPA documentation requirements — including full integration with MES and traceability via MEK Catch software.
High-precision Marantz solder paste inspection system for electronics assembly quality control
The SMT AOI range combines 2D and 3D inspection for surface-mounted devices, ensuring precise component alignment, polarity, and solder joint integrity. High-speed cameras and AI algorithms detect missing, misaligned, or defective components with minimal false calls.
These systems integrate seamlessly into SMT lines, supporting both inline and offline configurations, making them ideal for high-volume production or prototype verification.
Accurate solder paste volume and placement are essential for reliable solder joints. Marantz’s Solder Paste Inspection systems use 3D metrology to measure height, volume, and area, ensuring consistent paste deposition. Early detection of printing defects significantly reduces downstream rework and improves first-pass yield.
For mixed technology boards or power electronics, Through-Hole AOI systems perform detailed checks on wave-soldered joints, verifying correct pin insertion, solder coverage, and polarity. These robust systems detect bridging, insufficient solder, and open connections, providing consistent inspection across complex assemblies.
In harsh or high-reliability environments, Conformal Coating AOI ensures protective coatings are applied accurately and uniformly. Using UV light inspection, Marantz systems identify missing, excessive, or misapplied coating, ensuring components are fully protected without covering restricted areas such as connectors or test points.
Marantz offers Desktop AOI systems for manufacturers seeking cost-effective inspection without compromising performance. Ideal for low- to medium-volume production, R&D, or repair stations, these compact solutions deliver the same high-resolution imaging and AI-based analysis as inline models.
For high-volume environments, inline 3D AOI systems provide fully automated inspection between SMT stages or post-reflow, ensuring continuous process control. Stand-alone 3D systems are also available for off-line verification, sampling, or analysis tasks.
These solutions feature AI-driven defect classification and automatic learning algorithms that adapt to new board designs, reducing programming time and false-call rates.
Marantz Electronics integrates AI-powered image processing and true 3D measurement into their latest AOI systems, enabling rapid defect recognition and precise dimensional analysis. With machine-learning capabilities, the system continuously improves accuracy by learning from operator feedback.
The intuitive user interface simplifies inspection setup, data reporting, and traceability, aligning with Industry 4.0 and Smart Factory standards. Integration with MES and data analytics platforms helps manufacturers monitor quality trends and optimise production processes.
