The MicroChine’s Probe Brake feature instantly stops all rotary machining at a selected layer depth for nondestructive multilayer repair.

In use, the Probe Brake cable is attached to the PROBE BRAKE Receptacle on the front panel of the system power source. The opposite end of the Probe Brake cable must be connected to a connector pin, component lead, or a soldered-on extension of the circuit board assembly. The connection point must have electrical continuity with the internal conductor to be repaired. A schematic diagram or layout artwork of the printed wiring assembly (PWA) is a great aid in locating the most effective connection point for the Probe Brake cable. The electronic Probe Brake circuit stops the MicroChine instantly when the working drill or mill makes contact with the internal layer of circuitry, in continuity with the Probe Brake lead, and the Status LED illuminates Red in color. Once the brake circuit has stopped the motor, the finger switch or foot pedal must be released before the motor can be started again.
