Abstract: |
first published in the 2012 IPC APEX EXPO technical conference proceedings. Twenty-nine different cells phones have been disassembled, ground up, dissolved and analyzed for elemental content, mainly for information about the metals present in the phones, but also for some metalloids and non-metals.
