Abstract:
1. A method for manufacturing a plurality of solder reflow surface mount microelectromechanical system (MEMS) microphones, the microphone comprising: providing an unsingulated panel comprised of a plurality of individual rectangular substrates, each rectangular substrate comprising: mounting a MEMS microphone die to the top surface of each individual substrate in the panel of unsingulated substrates, and electrically coupling the MEMS microphone die to at least one of the first plurality of metal pads on the top surface of its respective substrate; providing a plurality of single-piece rectangular covers, wherein each individual rectangular cover is formed from a solid material and has a top portion and a sidewall portion, the sidewall portion supporting the top portion and adjoining the top portion at a substantially perpendicular angle and having a predetermined height, an exterior surface, an interior surface, an attachment surface, and an acoustic port disposed in the top portion of the rectangular cover and passing completely through the rectangular cover, wherein the acoustic port is disposed in a position offset from a centerpoint of the rectangular cover; attaching a single-piece rectangular cover to each individual substrate on the panel of unsingulated substrates, one cover to each individual substrate, singulating the substrate panel into individual MEMS microphones.
