APPARATUSES AND SYSTEMS FOR SELECTIVELY APPLYING A PROTECTIVE COATING TO ELECTRONIC COMPONENTS AND METHODS RELATED THERETO

摘要

An apparatus for applying a protective coating to electronic device assemblies or other substrates may include a tray capable of holding multiple substrates. The tray can be selectively closed over the substrates. Lower and/or upper tray elements may include pre-formed masks thereon, which masks correspond to locations where protective coating materials should not adhere to the substrate. The masks may include a structural portion and a sealing portion. The structural portion may keep a substrate elevated to maintain an opening or channel through which protective coating materials may be applied to unmasked portions of the substrate. A sealing portion of the mask may engage the substrate to restrict flow of the protective coating material to the masked portion. Each tray may contain multiple substrates. A carrier may support multiple trays. Dozens and potentially hundreds of substrates may be carried by the carrier for simultaneous application of the protective coating.
