Tech Etch has six decades of experience and expertise specializing in manufacturing precision-engineered thin-metal components, flexible printed circuits, and EMI/RFI shielding, across three locations in the United States (Plymouth, Massachusetts; Fall River, Massachusetts; and Litchfield, Minnesota). The company partners with leading global customers in the aerospace, alternative energy, military, medical, telecommunication, and electronics industries that have highly complex, precise designs, and demanding regulatory requirements.
Tech Etch has designed and developed a robotic spray coating process used to apply conductive carbon and graphite coatings to battery current collectors, fuel cells, thin-metal cathode grids used in implantable pacemaker batteries, and other energy storage devices that require low-resistance coatings. This coating provides a protective layer to slow down the erosion of the base metal and therefore helps to extend battery life.
