In today’s ultra-competitive electronics manufacturing landscape—from smartphones to medical devices—the Printed Circuit Board (PCB) is the silent hero. Yet as these boards grow denser and more complex, detecting tiny, critical defects becomes increasingly challenging. That’s where Intelgic steps in with their next-gen PCB Board Inspection technology, merging machine vision systems, micron-level defect detection, and robotic imaging systems for a revolutionary inspection process.
The Inspection Imperative for Modern PCBs
PCBs now host vast arrays of micro-components—SMDs, BGAs, resistors, capacitors—stacked across multiple depths and miniaturized geometries. Manual or rudimentary optical inspection simply can’t scale to catch subtle issues like misplacements, solder irregularities, or microscopic substrate damage.
- Complex multi-layer boards with hundreds of tiny parts
- Depth variation ranging from flat substrates to tall components
- Critical space for defects such as solder bridges, lifted pins, or substrate scratches at the micron level
Intelgic’s Automated PCB Inspection Solution
Intelgic addresses these challenges with a comprehensive system that pairs machine vision and AI with precision robotics:
Multi-Focus Vision and Microscopic Imaging
Using high-resolution cameras and telecentric lenses, the system performs multi-focus imaging, capturing stacked visuals at different focal points across the board’s Z-axis. These are then stitched into one ultra-clear, deep-of-field image.
Precise Component Detection and Verification
AI algorithms detect and categorize components—recognizing SMD types, reading serial labels, and confirming accurate orientation and placement vs. BOM/CAD models. Missing, extra, or misaligned parts trigger real-time alerts.
Micron-Level Defect Detection
Thanks to ultra-high-resolution imaging and advanced AI analytics, defects as small as a few microns—like solder bridges, cold joints, tombstoning, or substrate scratches—are reliably detected.
Robotic Imaging Systems
Intelgic’s 3-axis robotic rail platform moves the camera and lighting smoothly across X, Y, and Z axes. This enables totally consistent imaging even for large or irregularly shaped PCBs. Height is adjusted in real time to cope with component variation.
Dynamic Lighting and Real-Time Reporting
Adaptable lighting modules—coaxial, ring, or dome—track with the camera to maintain consistent illumination. AI-inspection results are generated in real time, integrated with MES systems, and logged with full traceability.

Real-World Use Cases
Consumer Electronics
In smartphones and tablets with ultra-dense boards, this system prevents errors like misplaced 0201 capacitors and microscopic solder flaws—boosting first-pass yield and reliability.
Automotive Systems
ECUs and BMS boards demand flawless soldering. Robotic AOI ensures defect-free builds by inspecting high-density PCBs with precision, spot-checking lifted pins or cold joints.
Medical Devices
Insulin pumps, diagnostic equipment, and implantable PCBs require microscopic inspection for coating flaws, solder debris, and labeling accuracy. AI-powered AOI brings unmatched consistency.
Aerospace & Industrial Controls
PCBs in avionics or industrial robots need to function flawlessly over years. Micron-level inspections ensure the reliability required in mission-critical environments.
