System Plus Consulting is publishing a reverse costing report on the
microphone from AAC Acoustics available in the Apple Iphone4 smartphone.
This device is an analog MEMS Microphone using a free-floating diaphragm, and
a capacitive sensing.
It offers a full integration of a MEMS microphone and an amplification ASIC,
both provided by Infineon, in a 3-pin LGA package.
This microphone is for consumer applications: smartphones, cellphones.
The report provides complete teardown of the microphone MEMS with:
- Detailed photos
- Material analysis
- Schematic assembly description
- Manufacturing Process Flow
- In-depth economical analysis
- Manufacturing cost breakdown
- Selling price estimation
