The PCB manufacturing process generally includes a final electrical test to verify net continuity and the absence of shorts on the board. In some markets, the increased complexity and variety of pcbs, along with decreasing volumes have determined an extensive use of flying probe type test systems for electrical test.
The longer test times of flying probers, as compared to grid testers, are offset by the benefits of quick set-up and the elimination of expensive bed of nails fixtures, providing double-side testing ready to go as soon as the PCB comes off the manufacturing line
Seica has added another significant benefit to its BBT line,  in the form of automatic loaders/unloaders specially designed for handling today’s variagated production types and volumes.

The Seica range includes:
- Flying probe systems with 4 (2+2) or 8 (4+4) probes and automatic handling (BBT line)
- Flying probe systems with 4 (2+2) probes and manual handling (BBT line)
