Nokia Lumia 920 Camera Module with OIS Reverse Costing Analysis

     Apple initiated the trend of integrating three MEMS microphones with the iPhone 5. Two manufacturers compete to integrate their analog microphones, Knowles which largely dominates the MEMS microphone market (with half of the business) and AAC which is ranked No. 2 but is the main source for the iPhone5. Both components are interchangeable in the iPhone 5, thus providing similar package/functionalities/price but with two different processes. AAC Technologies continues to rely on Infineon for the production and design of the MEMS die, but compared to the ones integrated in the previous iPhone the new design integrates corrugations in the membrane allowing to relieve stress under maximum strain. The MEMS Microphone uses a free-floating diaphragm. The common sensing principle is capacitive. The component is provided in a specific 3-pins package, compatible with SMD process.

Both components are interchangeable in the iPhone 5, thus providing similar package/functionalities/price but with two different processes.

AAC Technologies continues to rely on Infineon for the production and design of the MEMS die, but compared to the ones integrated in the previous iPhone the new design integrates corrugations in the membrane allowing to relieve stress under maximum strain.

The MEMS Microphone uses a free-floating diaphragm.

The common sensing principle is capacitive.

The component is provided in a specific 3-pins package, compatible with SMD process.

This report provides a complete teardown of the MEMS microphones with:

- Detailed photos
- Material analysis
- Schematic assembly description
- Manufacturing Process Flow
- In- depth manufacturing cost analysis
- Supply chain evaluation
- Selling price estimation

Key Topics Covered

This publication is part of a set of two reports highlighting the first two MEMS microphone suppliers competing with new design in Apple iPhone 5 smartphone. The two reports are available separately or you can benefit from a special bundle offer buying both of them.
