Interesting thread and links on Microsofts billion$+ issue with X-box failures attributed by some to joint failure due to thermal cycling see contents and links.

Hello, I'll try to translate - hope my english will be good enogh - the parts of the article which are most interesting with respect to lead-free: ---------------------------------------------------------------------------- -------------------------------------------------------------- While Microsoft gives no official information whether the not acceptable high failure rates of Xbox360 depend on basic failures of the hardware design or on untidy production. Meanwhile the people at Redmond work on a complete redesign. This was published by Dean Takahashi, author of the book "Opening the Xbox", in an article published by the San Jose Mercury News. (... some informations an the inside graphic chip design...) The smaller size of the chip will not only lead to cheaper production but as well to lower current consumption. This will improve the temperature level inside the housing and lower the noise level of the fan. Most of all the lower heat level shall reduce the number of failures of "Red Ring of Death" (PROD). At the moment Microsoft manages this by mounting an additional cooling element, connected by a heatpipe to the graphic-chip-heatsink. Experts suppose that the leadfree solder used on the board becomes brittle due to the high number of temperature changes. (... information on commercial aspects....) A few days ago Microsoft announces to expand the warranty period to three years for failures of the PROD-type ... Customers who had to pay for repair of the PROD-failures will get their money back from Microsoft. Specialists suppose that about one of three Xbox360 early or late will get that PROD-failure. ---------------------------------------------------------------------------- ---------------------------------------------------------------- That was roughly the contents of the mentioned link. At the bottom of that article there is an other link which leads to some more details. I'll try to catch the most interesting points of that: ---------------------------------------------------------------------------- ---------------------------------------------------------------- ... dealers as well as customers have complained about the high failure rate .... Microsoft will save 1.05 to 1.15 billion dollars for the warranty program. ..... The failure rate of the Xbox360 at the start of delivery in November 2005 was at about 50%... in between Microsoft has delivered about 10 Million of Xbox360 worldwide. .... The warranty program is valid not only fo the US but as well all over the world. ---------------------------------------------------------------------------- ----------------------------------------------------------------- Regards Wolf-Dieter Schmidt Industrial Engineering ----------------------------------------------------------- THALES Defence Deutschland GmbH Land & Joint Systems Ostendstrasse 3 D-75175 Pforzheim - Germany ----------------------------------------------------------- Phone: +49 7231 15 3386 Fax: +49 7231 15 3390 mailto: [log in to unmask] http://www.thalesgroup.com Registered Seat: Berlin Commercial Register Charlottenburg HRB 93875 B Managing Directors: Klaus D.
