8000 Dimensions, 3 Minutes, One Machine

How an international PCB trader hit telecom-grade inspection standards without scaling floor space

8000 Dimensions, 3 Minutes, One Machine

Executive Summary

An international PCB trader specializing in antenna boards faced an ambitious challenge: inspect over 8000 dimensions per board—across 200 transmitting units—while holding inspection time under 10 minutes. Traditional systems took over 40 minutes and required multiple machines running in parallel. Fermi Vision delivered a purpose-built workflow using a dual-phase pre-scan and high-speed fly-capture process that completed inspection in under 3 minutes—on a single machine.

This case exemplifies the intersection of speed, precision, and intelligent sequencing—delivering factory-level throughput with minimal footprint.

Background: Scaling Inspection Throughput

High-volume antenna boards feature hundreds of densely packed circuits, each with strict line width and spacing requirements. Accurate inspection typically requires:

  • High magnification without sacrificing field of view
  • Fast image acquisition across large surface areas
  • Efficient sequencing across thousands of measurements

Traditional methods struggle to balance these needs without scaling up equipment and manpower.

Fermi Vision's Innovation

Instead of treating each transmitting unit as a separate measurement loop, Fermi Vision designed a hybrid strategy:

  • Pre-Scan Optimization: Scanned the full board at low resolution to establish a coarse map
  • Fly-Capture Pass: Executed rapid, high-res measurements only on identified targets using dynamic path planning

This minimized movement, eliminated redundant passes, and kept cycle time under 3 minutes.

Results

  • Time Saved: Cut total inspection time from 40 minutes to <3 minutes
  • Equipment Consolidation: From 6+ machines to just one
  • Accuracy Maintained: No compromise in dimensional precision

With Fermi Vision's help, the trader met aggressive SLAs for high-volume telecom customers while simplifying floor layout and reducing operator demand.

This level of intelligent process engineering is a hallmark of Fermi Vision's commitment to scale without trade-offs.
