February
15, 2002, Woburn, Massachusetts - Chomerics, a division of
the Parker Hannifin Corporation, has introduced the ECOPLATE™
metallic conformal coating process, an automated system that
applies a pure metal coating over plastic or metal electronic
housings. In the patent pending ECOPLATE process, a metal
film is atomized and robotically sprayed onto enclosure parts
under controlled speed, particle size and temperature conditions.
The resulting 100% metal conformal coating provides uniform
coverage with no runs, edge pulls, corner puddles or voids.
Shielding performance of the ECOPLATE 5030 tin/zinc alloy
exceeds 75 dB from 100 MHz to 10 GHz. Coatings can be applied
as thin as 12.5 µm (0.0005 inch). The low-temperature
ECOPLATE process is free of solvents and corrosives, making
it ideal for thin-walled, plastic injection-molded parts.
It also replaces conversion coating on metallic enclosures.

Use of the ECOPLATE
system eliminates wastewater and vapor treatments, and the handling
of flammable materials required with traditional painting and electroless
plating methods. There are no solvent-bearing particulates or mask
residues to wash off with chemicals. These benefits, together with
low tooling costs, make the ECOPLATE system an economical solution
for both low and high volume applications. Applied costs are typically
10-40% below current alternative painting and plating methods.
Chomerics,
a division of Parker Hannifin's Seal Group, provides a wide range
of EMI Shielding and Thermal Management materials and services to
OEM electronics companies around the world in the Telecom, Information
Technology, Power Conversion, Military and Automotive markets. Since
1961, Chomerics has been the primary force in the development of electrically
conductive elastomers for use as extruded, molded and form-in-place
EMI gaskets. Chomerics also offers an extensive family of thermal
interface materials, which transfer heat from electronic components
to heat sinks.
