Yole Développement is proud to publish the reverse costing report on the AKU230 microphone designed by Akustica, a member of the Bosch Group and manufactured by Bosch.
The AKU230 is a digital MEMS Microphone using a free-floating diaphragm, and a capacitive sensing.
It is based on a silicon circuit combining the MEMS process on the ASIC process in a single die, integrated in a specific 6-pin LGA package.
This microphone is targeting high-end consumer applications: notebooks, laptops…
This report provides a 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
