SGH GS6 Fingerprint flyerSecond generation Samsung Galaxy fingerprint sensor: same capacitive technology but totally different design
For the second time Samsung introduces in its products a fingerprint sensor based on PCB capacitive technology, but with significant innovations. Samsung is following the choices of Huawei and Apple to have a more reliable sensor.

The Galaxy S6 home button uses again the particular fingerprint sensor technology developed by Synaptics, but introduces  a new capacitive and die technology.

This full Reverse Costing analysis has been conducted to provide insight on technology data, manufacturing cost and selling price of the Samsung Galaxy S6 Home Button Fingerprint Sensor.

Samsung’s technological choice for the second fingerprint sensor is to continue using Synaptics’ PCB technology but modify totally the capacitive sensing technology, increasing the processing capability of the CMOS and innovative method to detecting the presence of an object. Unlike the Galaxy S5’ fingerprint, it does not require anymore to swipe the finger to get the finger image.

Located above the home button, the 15.9x6.4 mm sensor is incorporated within a rectangular shaped housing composed of an aluminum ring and an aluminum base. The sensor is protected by a white plastic cover and supported by innovative assembly of rigid and flex PCB.
The report includes comparisons with Galaxy S5 fingerprint sensor and with the latest Apple’s and Huawei’s fingerprints buttons.

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.
