Yole iPhone5S MEMS Microphones Flyer.pdf -Set of two reports highlighting new designs and processes from the first two MEMS microphones suppliers

In this version of Apple iPhone, Knowles succeeds in integrating two MEMS microphones out of the three present in the phone. The third microphone is from AAC Technologies which was also already present in the previous iPhone version.

Apple thus uses the same MEMS microphones suppliers for the iPhone 5S, but each of them modified the design and the manufacturing process of their components to improve them by making them more robust.

Compared to the microphone used in the iPhone 5, Knowles major changes include the number of transducers of the MEMS die (impacting directly the die size) and the thickness of the backplate.

On its side, AAC Technologies also modified the design of the MEMS die (still supplied by Infineon) and the thickness of key layers.

Discover in this set of two reports the latest evolutions from the two MEMS microphone leaders.

Across the Enterprise, from marketing to purchasing and R&D, product manufacturing cost is a major factor which has to be measured and then optimized. Since 1993, System Plus Consulting’s mission has been to develop and sell the right tools and services to meet these costing requirements.

System Plus Consulting utilizes an engineering approach to cost. Cost models and technology expertise are combined to provide customers with an accurate and objective estimation of manufacturing costs and selling prices.

Headquartered in Nantes, France, System Plus Consulting is specialized in technology and cost analysis of electronic components and systems. During our 20 years in business, we have built and refined detailed cost models as the primary tools for hundreds of analyses. The highly qualified System Plus cost engineers combine broad and deep skills in semiconductor and electronics technologies with years of experience in cost modeling.

We offer:
− Custom reverse costing analyses: technology analysis followed by cost evaluation
− Standard reverse costing reports: regular publications on innovative products (available from our catalogue)
− Costing tools: software tools combining models and data to perform cost analysis

System Plus Consulting analyzes any type of electronic devices and systems, with a special focus on semiconductor technologies. Major fields of technology and cost expertise are:
− Integrated Circuits
− Power Devices and Modules
− MEMS & Sensors
− Photonics: LED, Image Sensors
− Packaging including wafer level
− Electronic Boards and Systems

Our analyses are used by Purchasing Departments to measure their suppliers’ cost structure, R&D Departments to confirm technological choices depending on their impact on costs, and Benchmarking/Marketing Departments to monitor the products on the market.

System Plus Consulting is committed to provide a high level of service:
− Delivery of reports and custom analyses with a minimum lead time.
− Results presentation and online Q&A sessions when support is needed.
− Open methodology and full confidentiality in order to maintain a trustful collaboration.

Since 2008, our partnership with YOLE Développement has allowed us to stay at the forefront of technologies and has added a market view to our reports.
