This document outlines the HFT pixel identification naming conventions used in high-energy physics experiments. It details the structure of pixel coordinates within chips, focusing on rows and columns defined by a right-hand rule. The naming follows a systematic approach to ensure clarity in sector numbering and chip layouts. Key specifications include pixel identification in sectors 1-10, with corresponding ladder and chip configurations, and methodologies for wire bonding edge parameters to facilitate consistent implementation in experimental setups.
