Alice Silicon Strip Detector Module Assembly with Single-Point TAB Interconnections

The silicon strip detector (SSD) modules cover the two outermost layers of Inner Tracking System of ALICE. The SSD collaboration performs the module assembly in several locations in Europe. Mass production of the SSD modules was launched during autumn 2004 and presently all the sites are producing the SSD modules successfully. The bonding yield of spTAB interconnections is approaching close to 100%. This paper describes the assembly phases and bond process development for SSD modules, including discussion on the most probable rootcauses of failures and the long-term reliability of the interconnections.
