Nokia 6070 Mobile Phone Teardown

26 October 2007
The following is an overview of a teardown analysis conducted by IHS Technology Teardown Services.

Main Features

Nokia 6070 is a low-to-mid range tri-band GSM/GPRS/EDGE (850/1800/1900 or 900/1800/1900) phone in traditional "candybar form factor. Main features include a 1.8" 65K color CSTN display, a VGA camera, WAP browser, stereo FM radio, IrDA and USB connectivity.

Overview

The Nokia 6070 is a candybar phone offering basic camera phone plus a few extra features at an affordable price. The Nokia 6070 comes in a candybar form which, honestly, does not raise any surprise. However, for people who basically just want a simple phone with ease of use, the Nokia 6070 offers more than enough with its tri-band capability, a camera and a 65K CSTN display. Yes the camera has a relatively low resolution and the screen is not state-of-the-art, but in this segment, price tag, reliability and durability are far more important to consumers.

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 4.9M units over a 2-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) rarely have a large net effect on our final analysis because of this.

Design Forecast Tool Notes

Per iSuppli research we estimate a total of 137M EDGE Tri-Band phones in 2007 global market. ISuppli lifetime production volume estimates are based on the assumption of 2-year life span and the company's current market position in this segment.

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 and 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

Country of Origin / EMS provider

This Nokia 6070 is labeled ""Made in Hungary" (final assembly, that is). Hungary seems to be a popular Manufacturing site for Nokia as we have seen quite a few Nokia phones that are labeled ""Made in Hungary". It is assumed furthermore that the plastics and other mechanicals, as well as the assembly of the PCBA took place in Hungary to minimize costs.

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 display 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 / Complexity

The Nokia 6070 has a total components count of 463 of which 73 are mechanical. In general, Nokia has fewer components than other competitive phones due to its more integrated and modular design approach. Among the 4 competing phones that we are analyzing, the 6070 has the fewest components, both electronic and mechanical. The Low components count reflects well that it is not a particularly feature-rich phone. Mechanically speaking, with 73 components, it is in line with other bare-bone Nokia candybar phones that we have seen.

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 affected by the assumed production volumes (which increase or decrease the per unit amortized cost of certain NRE, tooling and other up-front charges), as well as the country of final assembly, being Germany in this case, where our assumed loaded skilled (technical) and semi-skilled labor rates is one of the highest worldwide.

Design Notes

The Nokia 6070 appears to be a common Nokia design in terms of major ICs suppliers. As in many Nokia phones, the 6070 incorporates TI's DBB, ST Micro's ABB & RF Transceiver.

In the PAM section, the 6070 features a Renesas quad-band Power Amplifier. Renesas is believed to be one of the PAM suppliers while RFMD, which has been the prime supplier for PAMs in Nokia's designs, is also supplying PAMs for this particular model. The quad-band amplifier usage in this tri-band phone is justified by the fact that Nokia has two versions of 6070 which support either 850/1800/1900 or 900/1800/1900 and using a quad-band capable ICs can leverage the volume and also simplify the manufacturing process. By the same token, In the RF section, the phone also features a quad-band RF transceiver.

Interestingly in the memory section, we see a ST Micro's MCP instead of the usual Samsung chip. In this case, Nokia probably has dual-source for this memory MCP and based on our research, as in many of the Nokia phones, Samsung should be also playing in this section.

In addition, the phone also feature a ST Micro's image processor and a NXP's FM Radio chip that we have seen in many other Nokia phones we analyzed. Indeed, NXP seems to be the sole supplier of FM radio chip to many different manufacturers.
