Abstract	This paper reviews the bus tapes used for the barrel and end cap detectors for the ATLAS ITk strip detector. The long cooper/polyimide tapes with narrow track and gap are very challenging to produce with an acceptable yield. Two different technologies for these tapes are compared. After several iterations, barrel and end cap tapes are in production at two different manufacturers. Results form the electrical and dimensional QC show that both approaches meet the tight specifications. Tests of the radiation tolerance are also discussed.
