article imageIntel to strip Lead from Chips Processors

Intel will remove all the lead materials used in PC chips.
Intel Corp. says it is stripping out the tiny amount of lead still contained in its chips.
Intel uses lead in combination with tin to connect the processor to the motherboard in computers. To comply with environmental requirements, it has removed so far 95 percent of the toxic metal since 2004 and plans to remove the remainder amount 0.02 grams by end of this year with new chips. Instead of Tin/lead solder combination, it will start using an alloy comprises of tin, silver and copper to do the same job.
Since lead causes environmental and public health dangers, Intel wants to phase it out soon to help the green cause.
Intel has been using new transistor materials that reduce power leakage while boosting performance. It also has been reducing emission of pollutants and recycling more water and raw materials.
Intel is taking an aggressive stance toward environmental sustainability," said Nasser Grayeli, Intel's director of assembly test technology development in the Technology and Manufacturing Group.
Other chip makers including Advanced Micro Devices Inc. (AMD) is also working on trying to reduce the lead content in the microprocessors, like Intel it could do the same with the new alloy tin, silver and copper solder. AMD started reducing lead content since 2005.
Environmental issues have become a paramount concern in the semiconductor industry and are not solely public-relations maneuvers.
Chips consume more power in laptops as well as in corporate data centers, so consumers want a better performance. As a result, the chip makers are working hard to give an efficient performance without consuming too much power.
Good move by Intel, AMD, instead of reacting only when others say so, they should do it proactively and use more environmental friendly products in their manufacturing process.
