Advanced SMT AOI Equipment for PCB Quality Control

Precision Inspection for SMT Assemblies
Marantz SMT AOI systems are designed to inspect SMT assemblies thoroughly, detecting missing components, miss-alignment, polarity errors, solder defects (bridging, insufficient or excess solder), component text and colour errors, as well as foreign objects on boards. By introducing these tools into the process immediately after reflow (or earlier), manufacturers gain valuable process feedback and reduce the risk of defective products proceeding downstream.

Advanced Technology and Flexibility
Marantz offers a broad range of AOI configurations—from entry-level desktop and inline units to full 3D inspection and dual-side (top + bottom) scanning systems. Key features include multi-angle cameras (up to 9 cameras: one top view, eight side views), telecentric lenses, multi-colour/angle lighting systems, Z-axis measurement of height, and intelligent software algorithms for defect detection and classification. These capabilities enable fast programming times and high throughput with accurate coverage, critical in mixed-model, high-mix SMT manufacturing.

Integration and Traceability
Beyond defect detection, Marantz AOI systems support production line integration and data management via process control software such as the “Catch System”. This allows real-time monitoring, defect trend analysis, and traceability of inspection results, elements increasingly demanded in high-reliability sectors (automotive, medical, defence).

The Benefits for Your SMT Line
By implementing Marantz SMT AOI equipment, manufacturers can expect:

• Higher first-pass yield and fewer costly reworks or scrap

• Early detection of process drift and defects, reducing downstream costs

• Reduced human inspection burden and higher consistency of results

• Scalable solutions, from standalone desktop units to fully inline systems, so your investment aligns with your production volume and budget
