Description

The PVA2000 introduces a clean, efficient process for applying conformal coatings while virtually eliminating labor-intensive masking operations. Utilizing a controlled atomized spray and a non-atomized flow coating process, the PVA2000 limits conformal coatings to a defined, preprogrammed coverage area. Film builds as low as 0.01 mm (0.0005") can be achieved across the desired surface.

The PVA2000 selective coating process results in greater material utilization with transfer efficiencies of 99%, a significant increase over dip, brush, or hand spray applications.

The PVA2000 features the most flexible and robust motion platform in the coating industry. An overhead gantry system featuring ball screw slides is driven by brushless DC servo motors. Optical encoder feedback on all axes ensures a closed-loop process and provides long-term reliability.

The PVA2000 offers motion in all axes simultaneously allowing the programmer to contour application heads around intricate devices and adjust the spray pattern width on the fly.

The PVA2000 comes standard with three-axes of programmable motion. In addition to traditional XYZ motion, the FC100 flow coating valve is mounted on a tilt actuator to allow angled access to the side of components and shadowed areas.

For greater motion capability, the PVA2000 is available with patented fourth-axis technology. Unlike competitive pneumatic or stepping rotational devices, PVA offers the only servo controlled fourth-axis option. Once a valve head is angled, PVA's fourth-axis motion allows rotation of the entire dispense head permitting access to all sides of a component. PVA's fourth-axis option is the most capable motion platform configuration for eliminating masking and working around densely populated assemblies.
