Description
The use of ultra-lightweight flexible Printed Circuit Boards (PCBs) in silicon-based particle detectors was initially pioneered for the ALICE Inner Tracking System (ITS1) and the STAR tracker in the early 2000s. In this context, thin and flexible interconnections made of µm-scale polyimide (e.g. kapton) and metal (e.g. aluminum or copper) were specifically designed, offering a low-mass budget material while exhibiting outstanding mechanical stability and electrical properties. Over two decades of continuous progress in the field of Printed Circuit Boards have brought forth contemporary machinery that provides numerous advantages and possibilities for further integrating this technology into upcoming experiments. The pursuit of these endeavors necessitates a sustained and substantial effort to meet the high standards required for experimental precision. This study marks the initial phase of an ongoing process, rooted in the concepts developed for the ALICE experiment. It introduces innovative approaches to microfabricate the PCBs and systematically characterizes them both mechanically and electrically. The preliminary results of integrating this technology with ALPIDE chips are presented, along with potential applications for forthcoming experiments.
