Yole Bosch SMI130 flyerBosch’s first 6-Axis IMU for Automotive Application combining 3-Axis Gyroscope and 3-Axis Accelerometer

MEMS are getting broadly adopted in the automotive industry and non-safety applications like in-dash navigation are now requiring low-cost and small footprint components.

The SMI130 combines a 12-bit 3-Axis accelerometer and a 16-bit 3-Axis gyroscope in a 4.5x3.0mm LGA packages which is AEC-Q100 qualified for automotive applications. The measurement range of the yaw rate sensor can be adjusted in up to five steps between ±125°/s and ±2000°/s; the acceleration sensor offers four different measurement ranges between ±2g and ±16g.

The gyro integrates a new process for the capping. Indeed, the classic "glass-frit" wafer bonding has been abandoned in favor of an eutectic Aluminum-Germanium bonding.

The accelerometer features a new design which uses now only one mass structure for the moving parts compared to three for the previous generations.

The SMI130 is designed for non-safety-critical applications in the automotive industry, including in-dash navigation and telematics systems such as toll, eCall, and alarm systems.

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.
