Excellon Automation announces the release of the next generation in drill tool monitoring for the printed circuit board industry. EFS (electric field sensor) technology is available exclusively from Excellon Automation. With EFS technology, the drill bit functions as a microwave antenna and sets the zero point upon first contact with the conductive PCB surface. Accuracy of 0.0002 inches is achievable, unencumbered by surface debris, variations in panel surface, adjacent burrs or spindle warm-up.

Since EFS technology is based on microwave energy, the maintenance associated with optical broken tool detectors is eliminated. If the tool breaks, the microwave energy changes, detecting the break. Broken tool detection capability ranges from 0.004-0.250 with no adjustment.

The EFS pressure foot is available as an option on all new multi-spindle drilling machines. A retrofit kit is available for direct replacement of the current LTC broken tool systems for all system, century and uniline drilling machines.
