Nokia 6120 Mobile Phone Teardown

12 February 2008
The following is an overview of a teardown analysis conducted by IHS Benchmarking.

Overview / Main Features

The Nokia 6120 Classic is a 15-mm 'thin' candybar form factor quad-band GSM/EDGE, and dual band WCDMA (UMTS) phone with HSDPA capability, a 2 megapixel fixed-lens camera, a 2.0 TFT color screen (small because of the conventional monoblock design), Bluetooth v2.0 (Broadcom IC used here is actually V2.1 compliant), and an integrated FM radio.

Target Market

Mainstream consumer segment.


Per Nokia's press release (April 2007): The Nokia 6120 classic is expected to begin shipping in the second quarter of 2007.." with an estimated retail price of ?260 before subsidies or taxes.

Pricing and Availability

Per Nokia's press release (April 2007): ""…estimated retail price of 260 Euros before subsidies or taxes." At the time of writing (Dec 2007), however, this model was found online from multiple e-tailers with prices as low as ~$250 USD for unlocked models.

Volume Estimations

For the purposes of this teardown analysis, we have assumed a lifetime production volume of 8.6 million units. . ISuppli lifetime production volume estimates are based on the assumption of 2-year life span and the company's current market position in the phone 'segment' (per DFT excerpt below).

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) rarely have a large net effect on our final analysis because of this.

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

ISuppli estimates unit shipments of 32 million HSDPA units in the 2007 global market. We further estimate 55 million units of 2 megapixel camera phones to ship in the 2007 global market.

Function / Performance

Functional testing was not performed on the Nokia 6120 Classic.

What Is Not Included in our 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.

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 are assumed to be performing almost all of their own manufacturing work in house at one of 10 plants placed worldwide (about 75%), and 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 included Elcoteq, Jabil and Foxconn (as of 2005).

Country of Origin / Volume Assumptions

Based on markings, the unit was assembled in Hungary. We have also assumed that custom mechanicals (plastics, metals, etc.) as well as PCBA population were performed at Nokia facilities in E Europe (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. It is understood that modern manufacturing processes, specifically for SMT manufacturing lines are far more influenced by capital equipment cost drivers, than local labor rate influences.

Design for Manufacturing / Device Complexity

Nokias, as a general rule, have fewer discrete mechanical and electronic components, for the same amount of functionality than their competitors. Furthermore, Nokia have a very modular approach to designs which make them simpler to manufacture, improving production cycle times and ease of re-work / repair.

The Nokia 6120 Classic has a total component count of 487 components (not including box contents), of which 92 are mechanical components.

The number of mechanical components usually is a direct driver of hand-assembly costs, whereas the electronic component count (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. The cost of manufacturing is also, to some extent, decreased in this case because of assumed labor rate applied for China.

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

What's interesting here to us is primarily the HSDPA capable core DBB. To date, all of the HSDPA capable phones torn down, except this model and the N95 featured Qualcomm MSM chipsets (6260, 6275, 6280 and 7200) exclusively. This is the first non-Qualcomm HSDPA solution we have seen. Though we cannot find what data rate this HSDPA is (1.8, 3.6, or 7.2 Mbps). The Nokia literature seems evasive on this point.

The Nokia 6120 Classic has most component commonality with the previously analyzed Nokia 6290 and even N95 models. The DBB used in the 6120 Classic is the Texas Instruments ""RAPIDO" (112E / NMP# 4377476), also seen in the N95, as well as the 'Flintsones'-themed duo of ST Microelectronic's ""BETTY" Chip (NMP# 4376535), and ""AVILMA" (NMP# 4396299) in the analog baseband slots. These same chips (especially ""BETTY") are found in multiple Nokia models and see a lot of re-use in multiple Nokia designs.

The RF transceiver is a custom model (NMP #4380206) from ST Microelectronics for Nokia, with RF Micro devices power amplifiers in both the WCDMA section and GSM/EDGE sections.

To support the user interface features, the 6120 Classic has a stand-alone image processor from ST Microelectronics to support the 2 MP camera module (STV0984) which we have also seen in many designs from Nokia. The Bluetooth baseband is provided by Broadcom in the form of the BCM2048 which is actually version 2.1 compliant (this is the first time seeing a product that is V2.1) and features, also on a single die, an FM radio receiver.
