The ECOPLATE process is free of solvents and corrosives. It eliminates the storage and handling of flammable materials required with traditional painting and electroless plating methods. No wastewater or vapor treatments are needed, and there are no solvent-bearing particulates or mask residues to wash off the chemicals. Shielding performance of the ECOPLATE tin/zinc alloy exceeds 75 dB from 100 MHz to 10 GHz. Coatings can be applied as thin as 12.5 μm.
