A high precision kapton cable to route the signals of the double sided silicon microstrips detector (SMD) to the front-end electronics has been developed. The mechanical and electrical properties of this cable are stable against variations in humidity and temperature and maintain the cross talk between adjacent lines below 3%. Electron beam photolithography and chemical etching have been used to produce a very dense signal router: 744 L shaped strips on a surface of similar or equal to 140 mn X 40 mm, corresponding to a strip pitch of less then 50 mu m. The R&D work to find the correct electroplating parameters for both input and output bonding pads, to allow for automated wire bonding, as well as the results obtained during the SMD mass production are described.
