• This full reverse costing study has been conducted to provide insight on technology data,
manufacturing cost and selling price of the Apple iPhone 6S Fingerprint Sensor & Home Button
Assembly.
• The new device has the same structure and capacitive technology than the fingerprint of iPhone 5S
and 6, but with significant innovations in term of sensor design, die process and packaging.
• Integrated in the home button, the 12.5x10.9 mm sensor is incorporated within a rectangular
shaped housing composed of a stainless steel ring and an aluminum base. The sensor is protected
by a sapphire window coated with two different materials and supported by innovative assembly
of dies and flex PCB.
• The fingerprint sensor allows it to scan the fingerprint just by pushing the button. The sensor has a
resolution of 10,752 pixels with a pixel density of 500ppi. It uses a capacitive touch technology to
take an image of the fingerprint from the subepidermal layers of the skin.
• The sensor is composed of two dies, one dedicated to the sensing and one containing the logic.
While the ASIC die has a 0.18µm manufacturing process, the sensor die is manufactured with CMOS
65nm technology and it is connected by mean of TSV and wire bonding to the flex PCB.

Reverse costing analysis represents the best cost/price evaluation given the publically available data, and estimates
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 contact us:
