Huawei P9 – Rear Dual Camera Module

• This full reverse costing study has been conducted to provide insight on technology data and manufacturing cost of

the Huawei P9 rear-facing dual camera module.

• This module integrates two CMOS Image Sensor from Sony (Exmor-RS Technology) with a 11.8M pixel resolution

and an aperture of f/2.2: a monochrome and a color sensor.

• The P9 camera module, with dimensions of 18 x 9.2 x 5.1mm, is equipped with two sub-modules each including a

Sony CIS, a closed loop VCM and a 6-elements lens. Doubling the number of cameras gives more light, vivid colors

and crisper details. Moreover, it compensates the fact that the module is provided without optical image

stabilization (OIS). The CIS are assembled on a copper metal core 4-layers PCB with wire bonding process.

Compared to the actual trend, an external ISP is present on the PCB board of the phone.

• The Sony Exmor-RS technology consists in a stacking of two separate chips with TSVs using optimized processes: a

pixel array circuit which uses a Back-Side Illuminated (BSI) technology, and a logic ISP circuit. For these sensors, an

all-new TSV process is used and surprisingly both sensors are very similar but show significant process differences.

Compared to previous Huawei P8 and iPhone 6s with similar resolution, the P9 provides a larger pixel size of

1.25µm.

• The report includes technology and cost analysis of the P9 dual camera module. Also, comparisons with Samsung

Galaxy S7 and iPhone 6S rear camera modules are provided. These comparisons highlight structures, technical

choices and manufacturing cost.

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 analysis with your information. Please contact us:
