Patent ID: 7934306

Claim:
A method for packaging micro electromechanical systems (MEMS) microphone comprising steps of: providing a base having a top; a bottom; multiple circuit blocks being defined on the base; multiple circuit assemblies being formed on the top of the base and respectively in the circuit blocks; and multiple contact assemblies being formed on the bottom of the base and respectively in the circuit blocks, and each contact assembly connecting to the circuit assembly in the same circuit block; arranging and mounting multiple microphone component assemblies respectively in the circuit blocks of the base; providing a frame comprising multiple frame holes corresponding respectively to the circuit blocks on the base; and multiple ribs being between the frame holes; mounting the frame on the base, and the frame holes respectively surrounding and exposing the microphone component assemblies; forming multiple microphone units by cutting the base and the frame along the ribs; providing a cover having a top; multiple annular walls protruding from the top of the cover; and multiple sound holes being formed through the cover and being surrounded respectively by the annular walls; mounting the microphone units on the cover and one-on-one mounted in the annular walls; and forming multiple MEMS microphones by cutting the cover and the base along the annular walls.
