dissipates through the drill bit resulting in damage to the board, or dissipates through the controller damaging
sensitive boards. STAT-VAC eliminates problems associated with static electrical discharge.
STAT-VAC Conductive Vacuum Hose was developed by Sierra Polymer in
cooperation with Excellon Automation Engineering and is original equipment on all Excellon Mark VII and later machines.
|Original equipment hoses made of PVC typically last 800 hours, while STAT-VAC will last approximately 12,000 hours.
