Latest Patents

Frushour's latest patent, the Printed Circuit Conductor Test System, introduces a unique approach for testing conductor lines within printed circuit boards. This system encompasses specially designed circuitry that allows for the controlled burning out of constricted regions in the printed circuit lines, ensuring that defects are meticulously identified. It integrates measuring circuitry to monitor resistance in the conductor path, alongside a generator that produces an electrical pulse.

The electrical pulse is cleverly generated by discharging a capacitor that was pre-charged to a specific voltage level. The system includes a pulsing circuit switch that strictly limits the pulse duration, thereby preventing damage from excessive heating on the circuit board. Moreover, monitoring circuitry with peak detectors and comparators is integral to the system, allowing for the detection of sudden changes in test current amplitude. This functionality permits the system to terminate the test pulse prematurely when burnout is detected, safeguarding the integrity of the circuit board.
