What is the Solder Joint Inspection & How does it work?

Solder joint inspection is a critical step in PCB and electronics manufacturing because it directly impacts product reliability and field failure rates. Automated Optical Inspection (AOI) systems scan each joint for voids, bridges, and mis‑alignments, providing rapid feedback to the production line.

The throughput of an AOI system is not a fixed number; it varies with the physical dimensions of the board and the speed at which the inspection head can travel. Larger boards require more scan time, while higher inspection speeds can increase the number of boards examined per hour.

A simple model relates throughput (boards per hour) to the inspection speed (V) and the board’s linear dimensions (length L and width W). By treating the scan path as a linear sweep across the board’s perimeter, the formula below estimates how many boards can be inspected in one hour.

\frac{V times 3600}{L + W}
V = inspection speed (mm/s)
L = board length (mm)
W = board width (mm)
