The Samsung SGH-C130 is an entry-level dual-band candybar phone. It comes with a 1.5 128x128 pixels 65K CSTN display, a WAP browser, polyphonic ringtones, speaker phone and vibrating alert.
The Samsung SGH-C130 looks really ""Samsung". In fact, it is just like a candybar version of some previous Samsung ""slider" phones. However basic, it does come with a color screen and a WAP browser for added values.
First time mobile phone users - also emerging market consumers.
Official press release not found - secondary sources on web claim Q2 2006.
Pricing and Availability
Available in India for Rs. 3,399 , or ~ $79 USD at time of introduction.
Based on Samsung's market shares, the strength and potential for sale in new emerging markets, 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 2.5 Million units over a 2-year lifetime.
As a reminder, teardown volume production assumptions are meant primarily to be 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 most recent revision of this tool iSuppli estimates shipments of 408 M GPRS handsets in the 2007 global market. Furthermore, we estimate shipments of 160 M dual band 900/1800 phones in the 2007 global market.

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 NotesSamsung Relationships / Manufacturing
Samsung makes all their mobile phones in house. About 70% of their products are made in Korea and 30% are made in lower cost countries such as China and India. Until 2006, Samsung had been designing and manufacturing (box build) its mobile phones in house although this approach seems to be changing with Samsung starting to approach EMS providers and ODMs to explore low-cost phone options.
Country of Origin / Volume Assumptions
This product is labeled as Made in China, furthermore, we have assumed that for this model, that PCB was also populated in China, and that custom mechanicals (plastics and metals) were also sourced domestically 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 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.
The issue of labor rates was revisited in Q2 2006 as we began to apply some research by one the major worldwide EMS suppliers and are now applying some of their research on total loaded costs by country and region to arrive at these new rates which are pronouncedly higher on the low end in China. Remember 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.
Design for Manufacturing / Device Complexity
The SGH-C130 is one of the very few Samsung candybar phones we analyze. Most of the phones we have seen are either clam-shell or ""slider" which would have much higher components count due to complexity. In the case of the Samsung SGH-C130, it has a modest total components count of 361 of which 75 are mechanical. Both of these counts are in line with the competing phones we analyze this quarter.
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.
The core design of the SGH-C130 is based on the two Agere baseband chips. Agere baseband used to be quite common in Samsung phones designs but seems to have faded recently until we saw these two in the SGH-C130. The PA is a dual-band one from TriQuint which integrates the antenna switch to ease the overall design. The RF transceiver is a fairly typical Si-Lab's Si4210-GM for this level of phones. A Yamaha YMU759C FM sound generator which is believed to be some variant of the popular (among non-Samsung design though) YMU759B presents in the user interface section. In fact, Samsung has been mostly using the YMU762 and YMU765 in their previous designs.
