Abstract	A production run of FE-I4 pixel readout chips (denominated FE-I4B) was submittedSeptember 2011 and first wafers were received in December. These chips are being usedto build the Insertable B-Layer upgrade for ATLAS, to be installed during the 2013-14shutdown. Results will be presented for detailed probing characterization of thesewafers, as well as measurements of chips on boards before and after irradiation.Based on these test results, the FE-I4B has been accepted for IBL production and thepower conditioning configuration, using on-chip voltage regulators, has beenfinalized.
