Abstract

Recent progress on designs of flexible circuits for the ATLAS pixel detector will be discussed. Thin flexible circuits can be used to provide power and signal connections between front-end (FE) readout chips and data acquisition chips on the pixel detector module. Fabrication of a prototype design has been completed and test beam measurements with a 16 FE chip flex module gave an efficiency of 98.4% and a position resolution of 13.8 μm for clusters consisting of one or two pixels.
