Winsonic WS661GX-LV5.0 Micro ATX Motherboard
Barebones motherboard - no CPU - from "Winsonic based on SiS's 946L/661GX (661GX-L) chipset with empty 775-pin CPU socket (Intel Pentium 4, Pentium D, Celeron D).
PC OEMS, kitters, consumers, retail outlets.
Pricing / Availability
Similar products retail for about $50 and up online.
For the purposes of this cost analysis we have assumed a total production volume over product lifetime of 200,000 units of this particular model.
Function / Performance
Functional testing was not performed on this device.
Pricing assumptions were generally very aggressive for this board - it was assumed that ""Winsonic" or the real Odm building this board is purchasing at worldwide lows as we understand them.
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 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 NotesCountry of Origin / EMS Provider
China was the country of origin assumed for PCBA manufacturing. EMS/ODM unknown.
Design for Manufacturing / Device Complexity
This motherboard is fairly well integrated and features an overall component count that is greatly reduced when compared with other 775-pin socket based motherboards analyzed over the course of the last year (form factors were different, and North/Southbridge chipsets were also different). At a total component count of 871, this Winsonic board is less than all other motherboards looked at thus far - the nearest being the Micro-Star MS-7184 Micro-ATX Motherboard, which was also a Micro-ATX board - and had a component count of 1090 (previously the lowest component count seen). That Microstar was based on an ATI North/Southbridge Chipset RS482/SB400.
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.
