HTC Touch HD2 Mobile Phone Teardown

Overview / Main Features

The HTC Touch HD2 is Windows Mobile (6.5) smartphone powered by a Qualcomm 1GHz SnapDragon processor which also features a large 4.3 inch LCD display. Much like the current trends of growing display sizes on the high end mobile devices, the HTC HD2 attempts to improve usability of smartphones by providing yet larger screen real estate.

The Touch HD2 features a first for Windows Mobile device: a capacitive touchscreen which we have seen now for over 3 years on the Apple iPhone as well as various Palm, Blackberry and Android devices. The HD2 features a very similar design to the Toshiba TG01 which we have previously analyzed that also features a heavy reliance on Qualcomm components.

Overall, the dual band UMTS and quad band GSM is designed for the North American market featuring the AWS spectrum compatibility for T-Mobile 3G network. The smartphone features a 5MP camera, WiFi, Bluetooth and GPS capabilities which has become the standard features set of high end mobile devices.

Volume Estimations

For the purposes of this teardown analysis, we have assumed a lifetime production volume of 500K 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.

HTC Touch HD2 Mobile Phone Cost Analysis

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

Country of Origin / Volume Assumptions

Based on markings, the unit was assembled in China. Furthermore, we have assumed that custom mechanicals (plastics, metals, etc.) were also sourced in China.

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 module), 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 HTC Touch HD2 has an overall component count of 1086 (excluding box contents), of which 833 components reside on the Main PCB assembly. Compared to other smartphones we've analyzed in the past, the Legend occupies the upper extremes of the complexity curve (>1000 parts).

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.
