Polar Toneohms are ideal tools for the electronics production environment. Able to locate shorts quickly and accurately on both bare and loaded PCBs, they provide a very cost-effective means of minimizing repair and rework of faulty PCBs that have been identified by pass/fail testing on an ATE system.
Manufacturers and assemblers of electronic printed circuit boards are constantly striving to:
- Increase production throughput
- Minimize rejects and scrap
- Reduce rework time and cost
- Maintain and improve quality
A significant percentage of electronics manufacturing and in-service defects are caused by PCB short-circuits or faulty devices loading the circuit. Automatic pcb test equipment or conventional fault detection techniques can be used to diagnose the presence of shorts, but not their physical location. In recent years, shorts location has become more difficult due to the introduction of:
- Multilayer boards
- Bus-structured circuits
- Densely-packed components
- Fine-line tracks
- Power and earth planes
The Toneohm 950 represents the definitive solution to all these problems. Employing innovative Vectored Plane Stimulus techniques, the instrument provides fast and accurate guidance to the origin of PCB shorts. From an operator's point of view, nothing could be easier to use - you just follow the arrows on the instrument's front panel!
