摘要:
A method for selectively removing portions of a protective coating from a substrate, such as an electronic device, includes removing portions of the protective coating from the substrate. The removal process may include cutting the protective coating at specific locations, then removing desired portions of the protective coating from the substrate, or it may include ablating the portions of the protective coating that are to be removed. Coating and removal systems are also disclosed.
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.
