PPVA
2000
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, reprogrammed 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.
The PVA2000 can be
configured with any combination of spray and dispense valves
to best optimize your process. A PVA applications engineer
can assist in developing a solution that best fits your
process. |
