• This full reverse costing study has been conducted to provide insight on technology data,

manufacturing cost and selling price of the Nexus 6P Fingerprint Scanner Assembly.

• The Nexus 6P is a smartphone designed and manufactured by Huawei. Likely the Ascend Mate 7,

the Chinese company integrates again a fingerprint of Fingerprint Card on the back of the device

but introduces significant modifications in term of resolution and packaging.

• Located on the back side of the smartphone, the fingerprint sensor of the Nexus 6P has dimensions

of 11.6 x 11.6mm. It is assembled on a square LGA package and is protected by metal support.

• The sensor has a resolution of 15,600 pixels with a pixel density of 508ppi. It uses a capacitive touch

technology to takes an image of the fingerprint from the subepidermal layers of the skin.

• The sensor die is manufactured with CMOS 65nm technology and is connected by mean of wire

bonding to the rigid PCB.

• The components also includes an ASIC die manufactued using a 0.5µm CMOS process and

connected to the flex PCB.

• This report includes comparisons with Ascend Mate 7 fingerprint sensor and with the latest

Samsung’s and Apple’s fingerprints buttons.

• Reverse costing analysis represents the best cost/price evaluation given the publically available data, andestimates completed by industry experts.

• Given the hypothesis presented in this analysis, the major sources of correction would lead to a +/- 10%correction on the manufacturing cost (if all parameters are cumulated)

• These results are open for discussion. We can reevaluate this circuit with your information. Please contactus: • Consulting and Specific Analysis
