Abstract
Provided is a MEMS microphone package having a sound hole in a PCB, which can ground-connect a metal case to a main board using an assembly process including bending and clamping an end of the case. The MEMS microphone package includes a tetragonal container-shaped metal case having an open-side to insert components into an inner space, and a chamfered end on the open-side to easily perform a curling operation, a printed circuit board (PCB) substrate to which a MEMS microphone chip and an application specific integrated circuit (ASIC) chip are mounted, the PCB substrate being inserted into the metal case and having a sound hole for introducing an external sound, and a support configured to support the PCB substrate in the curling operation and define a space between the metal case and the PCB substrate.
