Knowles SPM0408 MEMS microphone Reverse Costing
System Plus Consulting, Sep 2009, Pages: 78
Reverse costing report of the Knowles SPM0408 MEMS Microphone
- Analyze the cost of projects at the R&D level
- Enhance the negotiation power of purchasing managers
- Benchmark competitor’s products
Based on a complete teardown process the report provides an estimation of the production cost a swell as the selling price of the circuit.
Mostly used in cellphones, the Knowles MEMS microphones have been shipped at more than 1 billion units since their introduction. They use a specific surface mount designed FR4 type package , containing 2 separate dies: a capacitive MEMS microphone and an ASIC for signal amplification.
Since the last generation, several changes have been realized like the use of Deep Reactive Ion Etching for the MEMS cavity instead of traditional KO Hetching.
This report provides complete teardown and cost estimation of the component with:
- Detailed photos
- Material analysis
- Schematic assembly description
- Manufacturing Process Flow
- In-depth economical analysis
- Manufacturing cost breakdown
- Selling price estimation
