Nokia 6500 Classic Mobile Phone Teardown

28 February 2008
The following is an overview of a teardown analysis conducted by IHS Technology Teardown Services.

Overview / Main Features

Mid-range, WCDMA 850/2100, GSM/EDGE quad-band, single-camera 2.0MP candybar phone, with Bluetooth 2.0 EDR with A2DP, 1GB internal memory, and 16.7M 2.0 Inch TFT display. Video/audio playback and media streaming is also a common feature of newer, and especially 3G+ phones such as this. The 6500 Classic is the thinnest phone offered by Nokia.

Target Market

This phone is intended by Nokia to represent a mid-level 3G phone. This phone is the thinnest phone from Nokia and has a feature list that satisfies most common needs of consumers.

Regionally it should be more focused on those regions where WCDMA/UMTS (3G) networks are well deployed - such as Europe. See below for more specific regional availability.

Released

Announced May 31, 2007; Available 3rd quarter of 2007

Pricing and Availability

According to Nokia - the 6500 Classic "is expected to be available during the 3rd quarter of 2007 at an estimated retail price of 320EUR before taxes and subsidies. Currently, the phone is available through out Asia and Europe.

Volume Estimations

For the purposes of this teardown analysis, we have assumed a lifetime production volume of 1.8 M units.

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 116 million WCDMA handsets in the 2008 global market, furthermore we estimate unit shipments of 289 million 2-megapixel camera phones in the 2008 global market

Manufacturing Notes

OEM/ODM/EMS 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).

Managing 10 manufacturing facilities worldwide, Nokia performs the final assembly of the majority (more than 80%) of its wireless handsets in-house while utilizing ESM providers heavily for PCB assemblies, sub-assemblies and electronics modules such as camera modules. Furthermore, we estimate that at least 90% or Nokia's internal production takes places in low-cost countries such as China and India, with the remainder in mid and high-cost countries. Major external partners included Elcoteq, Jabil and Foxconn (as of 2007).

Country of Origin / Volume Assumptions

Based on label markings, the unit was assembled in Hungary. Furthermore, we have assumed that custom mechanicals (plastics, metals, etc. were sourced in Hungary due to the low labor cost in Hungary as well as Nokia's footprint there.

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 chargers), 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

At 518 total components count, of which 96 are mechanical, it is totally in line with other similar WCDMA Nokia phones previously analyzed. Mechanically, although it is in candy-bar form, it is actually the first one which has major components (the bottom enclosure, display module and main PCB) ""slide" into the main enclosure (instead of the usual plastic ""top" and ""bottom"). The design is similar to the 2nd Generation iPod Nano where everything ""slides" into the round, metal enclosure.

Having said that, the 6500 Classic may take a longer time to assemble, but is still not a manufacture-intensive product due to its low components count when compared to other competitors.

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

The Nokia 6500 Classic shares a great deal of commonality with the previously analyzed Nokia 6555 (also a cam WCDMA/UMTS phone) in terms of electronic design. In fact, all the major ICs including DBB, ABB, PM and RF transceiver are exactly the same.

Nokia to date has to most integrated design especially in the RF section. While most competitors employ more than 1 chip to perform both GSM+WCDMA transmit and receive, Nokia in most cases only has 1 single-chip in the RF section.

One noteworthy observation in this design is the use of MoviNAND memory (which we have never seen in other design) from Samsung. The MoviNAND is basically a MLC NAND Flash with MMC controller which acts like an embedded MMC card. In the case of the 6500 Classic, the 1GB of MoviNAND is probably more than enough for this type of phones and that's probably why we do not see an external MMC slot.
