LG KU380 Mobile Phone Teardown

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

Overview / Main Features

The LG KU380 is a basic 3G UMTS phone with Quad-Band GSM capabilities, based on a Qualcomm MSM6245 chipset. It features slider form-factor, a single 1.76 diagonal 262K 176x220 TFT display, dual cameras: a 1.3MP primary camera module, and a VGA secondary, and features Bluetooth. It also has the same hardware features and major components as the LG KU380 - they are virtually electronic hardware twins (with a few minor differentiators).

Overall - this phone is, at the time of writing, what has really become a mid-market mainstream phone with no particular standout features. Based on LG's press release, this should be a popular phone as it was taken up by many of the world's largest service providers, according to LG.

Target Market

Mainstream users - because of the sliding form factor, this phone is just one small cut above the LG KU250 which is part of LG's ""3G for all" initiative / marketing plan to reduce the cost threshold for 3G entry for consumers, per their press release. This phone, however, is essentially within the same cost parameters (with a few additional dollars in mechanical components because of the sliding form-factor) as the LG KU250, and therefore should also be seen as a mainstream oriented, entry-level 3G phone. LG themselves dub the phone (per their website): ""3G Mass Market Booster".

Release / Availability

Oct / Nov 2007 - per 3rd party republished press releases.

Volume Estimations

For the purposes of this teardown analysis, we have assumed a lifetime production volume of 1.2 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

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

From our Design Forecast Tool (DFT), we estimate unit shipments of 116 Million WCDMA handsets to ship in the 2008 global market, and we further estimate unit shipments of 301 Million 1 megapixel camera phones to ship in the 2008 global market.

We estimate LG's global unit market share in 2008 to be approximately 7% at the time of writing.

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

LG Relationships / Manufacturing

Per iSuppli's ""Global OEM Manufacturing and Design Analysis (GOMDA)", we estimate that retained the majority (nearly 97% in 2006) of its handset manufacturing in-house.

Only in recent years did LG start to use a number of Taiwanese ODMs for smart phones and low-cost GMS and CDMA phones.

Country of Origin / Volume Assumptions

This product, as is typically the case from our experience, was labeled as made in Korea. Furthermore, we have assumed that for this model, that the PCB was also populated in Korea, and that custom mechanicals (plastics and metals) were sourced locally as well.

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), 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

The LG KU380 has a total component count (less box contents) of 609 components, of which 105 are mechanical in nature - this is a very competitive component count for a phone with sliding mechanism.

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

The design revolves around a Qualcomm MSM6245 chipset (part of Qulacomm's Value Platform) - or basically a near turn-key solution from Qualcomm, as is often the case with phones based on a Qualcomm core baseband chip. This includes the MSM6245 baseband processor, the PM6650 power management chip (found in 90%+ of Qualcomm-based designs we see), and the Qualcomm RTR6275 RF Transceiver. In addition there are Skyworks and Anadigics in the PAM slots for GSM and WCDMA respectively, and a Toshiba NAND/SDRAM MCP in the memory slot.

Overall this is a fairly basic design of limited scope and cost.
