Abstract:
1. A method for manufacturing a plurality of solder reflow surface mount microelectromechanical system (MEMS) microphones, the method comprising: providing an unsingulated panel including a plurality of individual rectangular substrates, each rectangular substrate including: mounting a MEMS microphone die to the top surface of a plurality of the individual substrates of the panel of unsingulated substrates, and electrically coupling the mounted MEMS microphone die to at least one of the first plurality of metal pads on the top surface of its respective substrate, the MEMS microphone die being disposed directly over the acoustic port in the base layer of its respective substrate; providing a plurality of solid single-piece rectangular covers, wherein each rectangular cover has a predetermined shape and includes a top portion, and a substantially vertical and continuous sidewall portion that adjoins the top portion at an angle and that completely surrounds and supports the top portion, the sidewall portion having a predetermined height, an exterior sidewall surface, an interior sidewall surface, and an attachment surface; attaching one rectangular cover to each substrate of the panel of unsingulated substrates having a MEMS microphone die mounted thereon, singulating the substrate panel into discrete surface mount MEMS microphones.
