Abstract

A microphone packaging assembly (100) provides a printed circuit board (pcb) (106) for coupling to a microphone device (102) having a bottom acoustic port (104). The pcb provides an acoustic port opening (108) which aligns with the bottom acoustic port (104) of the microphone device (102). A solder pad pattern (110) is disposed on the pcb (106). The solder pad pattern (110) is configured to provide both electrical connection (114) and an incomplete solder seal (116) having purposeful acoustic leak to the microphone device (102). A conformable coating (126) provides a seal to the purposeful acoustic leak. A single acoustic test can be performed to detect proper environmental protection and acoustic sealing of the packaged assembly (100).
