Devices that are lead-free are marked with a circled “e1” and have the product code: NHxxxxxx. a. This device is lead-free. That is, lead has not been intentionally added, but lead may still exist as an impurity at <1000 ppm. The Material Declaration Data Sheet, which includes lead impurity levels and the concentration of other Restriction on Haz- ardous Substances (RoHS)-banned materials, is available at: ftp://download.intel.com/design/packtech/material_content_IC_Package.pdf#pagemode=bookmarks In addition, this device has been tested and conforms to the same parametric specifications as previous versions of the de- vice.
