3 This full reverse costing study has been conducted to provide insight on technology data, manufacturing cost and selling price of the MAX30102 Optical Heart Sensor from Maxim Integrated found in the Samsung Galaxy S7. The sensor is an optical heart-rate module and a pulse oximeter sensor in LED reflective solution. The main die features a photodiode area and an analysis part with an integrated ambient light cancellation system comprising a photodetector and a wavelength cut-off filter based on Maxim s proprietary technology. The component features two LEDs: an IR and a RED led. The LEDs are bonded on silicon substrates, the IR led is manufactured using AlInGaP material and the RED led using GaAs material. The component is outsourced for the LED manufacturing and package assembly. Compared to the previous generation, the footprint of the component increased a little but the performance based on the packaging and the electrical part are much more reliable. Thanks to some innovations, the MAX30102 device is very cost effective which enforce Maxim s leadership in this domain by SYSTEM PLUS CONSULTING, all rights reserved. 3

4 The reverse costing analysis is conducted in 3 phases: Teardown analysis Package is analyzed and measured The dies are extracted in order to get overall data: dimensions, main blocks, pad number and pin out, die marking Setup of the manufacturing process. Costing analysis Setup of the manufacturing environment Cost simulation of the process steps Selling price analysis Supply chain analysis Analysis of the selling price 2016 by SYSTEM PLUS CONSULTING, all rights reserved. 4

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

19 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: 2016 by SYSTEM PLUS CONSULTING, all rights reserved. 19
