Multitechnology system checks PCBs

Automated optical inspection, x-ray imaging, infrared cameras, and acoustic microscopy are teamed in NDT system.

As the complexity, density, and cost of printed-circuit boards (PCBs) continues to escalate-particularly related to embedded electronics for medical and other real-time critical systems-so does the cost of reworking defective boards. Most finished electronics are checked with in-circuit testing (ICT) of functional blocks; however, inline inspection systems would locate defects before additional value is added to a defective product, thereby reducing repair and rework costs.
