Nokia 6085 Mobile Phone Teardown

Main Features / Overview

Low-end of the mid-range quad-band GSM/EDGE clamshell with VGA camera, FM radio, Bluetooth and a 128x160 262K color CSTN passive LCD (monochrome secondary). No particular standout features otherwise.

Nokia 6085 Mobile Phone Main Image

Per Nokia press releases - this phone is a "camera phone at an affordable price. The Nokia 6085 emphasizes ease-of-use, up-to-date technology and enduring design to create a straightforward, familiar phone. The phone appears to be a mid-range phone aimed at the mainstream with no particular ""niche" as is often the case with Nokia's very broad range of products.

Released

Q4 2006 - Per press release.

Pricing and Availability

175 Euros estimated price per Nokia press release (excluding taxes and subsidies).

Volume Estimations

Based on Nokia's market share, and our estimates of market volume shipments by manufacturers and market segments (see iSuppli Design Forecast Tool (DFT) data below), we are assuming a total production volume for this model of 9.5 million units over a two-year lifespan for the purpose of this analysis.

As a reminder, teardown volume production assumptions are primarily used for our cost analysis in terms of amortized NRE and tooling costs, especially for custom components specific to the model being analyzed (mechanical components especially). Unless assumed volumes are different by an order of magnitude, minor changes in volume (say 1 million vs. 2 million) rarely have a large net effect on our final analysis because of this.

iSuppli's Design Forecast Tool (DFT) and Market Shares

As part of iSuppli's Design Forecast Tool (DFT), we forecast handset shipments by major design feature and manufacturer, as well as the number of design starts a manufacturer will have by feature set.

iSuppli estimates unit shipments of 245 million EDGE handsets in the 2007 global market, and more specifically we estimate unit shipments of 80 million quad-band EDGE phones this year.

Nokia 6085 Mobile Phone Cost Analysis

The total materials and manufacturing costs reported in this analysis reflect ONLY the direct materials cost (from component vendors and assorted EMS providers), AND manufacturing with basic test. Not included in this analysis are costs above and beyond the material manufacture of the core device itself - cost of intellectual property, royalties and licensing fees (those not already included into the per component price), software, software loading and test, shipping, logistics marketing and other channel costs including not only EMS provider and the OEM's margin, but that of other resellers. Our cost analysis is meant to focus on those costs incurred in the manufacture of the core device and exceptionally in some circumstances the packaging and literature as well.

Function / Performance

Functional testing was not performed on the Nokia 6085.

Manufacturing Notes

Nokia Relationships / Manufacturing

We do not currently know, down to the model, where specific models may be manufactured, or by what EMS/ODM. The only information we have for these teardown analyses is typically limited to what is noted (except for handset country of origin labeling, which are still used as the driving assumptions for manufacturing costs).

Having said all of this about relationships - Nokia is assumed to be performing almost all of its own manufacturing work in-house at one of 10 plants placed worldwide (about 75%). Furthermore, we estimate that approximately 80% or more of all production takes places in low-cost Nokia facilities, with the remainder in mid- and high-cost countries. Major external partners include Lite-On and Quanta (taking over from BenQ) for GSM handsets.

Country of Origin / EMS Provider

The product is labeled as Made in Hungary. We are therefore assuming that much of the manufacturing and integration is also taking place in Hungary.

Country of origin assumptions relate directly to the associated cost of manufacturing, where calculated by iSuppli. In the cases of ""finished" sub-assemblies (such as Bluetooth modules or camera modules), we do not calculate internal manufacturing costs, but rather assess the market price of the finished product in which case country of origin assumptions may or may not have a direct effect on pricing.

Remember also that labor rates are applied directly only to hand inserted components and systems in our bill of materials, and although regional assumptions do, these new rates do not have a direct effect on our modeled calculations of placement costs for automated SMD assembly lines. ""Auto" inserted components (such as SMT components) placement costs are calculated by an iSuppli algorithm which allocates a cost per component based on the size and pincount of the device. This calculation is affected by country or region of origin as well.

Design for Manufacturing / Device Complexity

Most of the phones we have seen that are either clamshell or ""slider" have higher components counts due to additional mechanical and electro-mechanical complexity owing to the ""splitting" of the design into two ""halves."

In the case of the 6085, this device has a total component count of 528 of which 99 are mechanical. This puts the Nokia 6085 in-line with other competing models with similar functionality in the clamshell form factor.

The number of mechanical components usually is a direct driver of hand-assembly costs, whereas the electronic component counts (and I/O count, density, etc.) are relative metrics for the more automated portion (namely SMT assembly) of manufacturing costs.

Component counts have a direct bearing on the overall manufacturing cycle times and costs, and also can increase or decrease overall yields and re-work. Our calculations of manufacturing costs factor counts and more qualitative complexities in the design.

Note that manual labor has a much smaller effect on auto-insertion assembly lines (for the Main PCB, for example), where manufacturing costs are much more capital equipment intensive and driven by these investment costs.

Design Notes

Nothing stands out in this phone as a breakthrough or innovation from a design perspective. It is essentially another demonstration of Nokia's commitment to component integration, design for manufacture and reuse of standard components. The design is quite similar to the recently analyzed Nokia 5500 (same core chips) - but minus the 3-axis sensor which was used for sports / pedometer functionality,
