I don't know about that site. It seems to be three nerds vs. the world. Here is another example of their work:Posted 03/03/99 4:05pm by Mike Magee Merced has got to have steel backplate A metallurgical reader of The Register has sent us facts and figures about different metals Intel may be using in its cartridge Merced design. The photographs, developed by Boots the Chemist in the St Ann's Centre in Harrow, are here. When we questioned Stephen Smith, who runs the Merced programme in the US, he told us he had no metallurgical knowledge and so therefore could not explain which metal was on the backside of the cartridge. However, the reader said Smith's comments were "most interesting" and sent us a set of numbers. The ratio is between material, heat conductivity and density. Here are his conclusions. Ag: 420:10.5 Cu: 395:8.93 Au: 310:19.26 Al: 200:2.7 Fe: 50: 7.88 Si: 0.7: 3? He thinks the backplate has got to be a copper alloy although we still favour steel, because of the weight. After all, the silicon is pretty light and even given the 560 gold contacts, there's something hefty there... And even given the metallurgy, Stephen Smith, the Merced programme manager, told us there was a pretty hefty heatsink on the back too. At this point, the chemist left us and gave some figures for both Cork, an organic substance, and rock, an indeterminate substance. Cork: 0.05:0.01 Rock:3: 2? If by rock he meant quartz, we think that Intel buys in its crystals and cork is so light it can float like a Kyocera mobile phone. We conclude from his observations that the backplate must be steel, as we first thought, thus making the package very heavy. It is, after all, pretty conductive. ®
