– Compatibility & Integration

Handling requirements include ESD protection using grounded wrist straps and conductive table mats. Cleaning employs dry, clean, filtered compressed air or nitrogen at pressures below 414 kPa (60 psi) with a grounded nozzle. Isopropyl alcohol cleaning solution requires adequate ventilation and skin/eye contact avoidance.
