Selective Conformal Coating Systems

The PVA650 is a closed-loop robotic platform featuring optical encoder feedback on all axes.

The PVA650's flexible robotic platform that is also ideal for potting, bead, and meter-mix dispensing applications. The PVA650 features a robust overhead three-axis motion platform suitable for inline or batch operations.

The PVA650 has many integrated features including:

•  Robotic system accuracy of 25 microns
• Patented servo-controlled optional four-axis motion featuring valve tilt and rotate
• Closed loop process control throughout gantry system
• Micron level encoder resolution for unparalleled accuracy
• Multiple dispensing applications or materials in one cell
• Onboard PC for unlimited program storage
• Exclusive PathMaster^® programming environment
• PVA's award winning global service network
