Nokia 6020 Mobile Phone Teardown

15 July 2005
The following is an overview of a teardown analysis conducted by IHS Technology Teardown Services.

Main Features

Mid-range VGA cam phone (no flash unit), candybar format, tri-band GSM/GPRS/EDGE with 65K color TFT screen. IrDA, but no Bluetooth.

Marketing/Positioning

This kind of phone, VGA cam-phone with no flash or Bluetooth, or a lot of other bells and whistles is a mid-range phone presently, but this kind of phone is quickly getting closer to the low-end of the spectrum. While Nokia still has plenty of lower-end phones, such as the Nokia 3100, 2100 and 1100 models (where features such as 'glow-in-the-dark covers' figure prominently on feature lists), the basic VGA cam phone will soon take it's place at the low end of the spectrum and is often already in the giveaway space with some service providers. The only feature adding some standout value in this phone is it's EDGE capability.

Relased in November, 2004, the Nokia 6020 candybar phone doesn't really standout aesthetically from other Nokia phones, and while Nokia tends to focus on the youth market using inventive shapes or often garish colors - their marketing materials, as well as aesthetic clues from the 6020, would indicate that this phone is aimed more at an adult mainstream market. The breadth of the Nokia portfolio is amazing, and it is often hard to tell why so many phone models are produced with more or less the same feature set - but given Nokia's internal modularity of design and repeat usage of components, merely changing the phone's shell to appeal to alternative market segments, has a relatively low cost impact to Nokia, compared with other, lower-volume OEM who can less afford to fragment their product lines in this manner.

About 48% of phones produced in 2005 will be camera phones. Furthermore, the sweet spot in camera phones has been the VGA resolution level for some time, and in 2005 we expect that about 80% of camera phones will be VGA resolution, and only 18% of cameraphone handset volume to be in the 1 to 2 MP resolution range. 1 to 2MP camera phones are expected to grow to about one quarter of cameraphone sales in 2006. Furthermore, with general handset unit manufacturing rates growing at a healthy rate during the coming years, camera module unit sales will grow substantially. Furthermore, of the 750M unit forecast for this year, about 10% of those produced are expected to be EDGE capable, such as the Nokia 6020.

Manufacturing Notes

Country of Origin - The Nokia 6020 was labeled as Made In China. Furthermore, we have assumed that all levels of sub-assembly were also produced locally, including Main PCB manufacturing as well as plastics molding and other custom mechanical component production.

Design for Manufacturing / Complexity - Nokia phones always stand above the rest in terms of elegant simplicity when it comes to design for manufacturing. Nokia phones typically have fewer total components (both mechanical and electrical) representing a high degree of integration at all levels. Modularity and simplicity of manual assembly seem to guide all Nokia designs. As mentioned many times, such touches as always using a socketed snap-in camera module is far less complex to manufacture than competing designs using flex circuitry and board to board connections. More complex designs such as the latter elevates hand assembly cycle times, increases the risk of failure and reqork, and also adds direct materials costs. The Nokia 6020 had very few mechanical components - an extremely simple design manufactured in one of the lowest cost regions in the world add up to very low overall manufacturing costs.

Design Notes

Internally the Nokia 6020 bears much resemblance to the Nokia 3220 analysis, sharing many of the major components (as we said above, this is the beauty of Nokia's high re-use across phones - commonalities between phones is by design and allows for variations in phones without a great deal of NRE expenses in creating derivative designs). This is classic Nokia design, using the same major manufacturers as usual (TI and ST Micro for DBB/ABB) - all ASIC-oriented with an emphasis on design integration and simplicity in manufacturing through reduced component counts, and simple mechanicals which allow for rapid manual final assembly with little rework. One good example are snap-in camera modules (as opposed to more complex flex circuit connections with board to board conencrtors, etc.) - used in most if not all Nokia camera phone designs.
