Samtec EDICON 2017 - A Vehicle For Insitu Glass Fabric Characterization

A PCB-based glass fabric characterization vehicle is presented that yields statistically worst-case glass skew for single-ended transmission lines. It also demonstrates the behavior of best/worst case differential trace pitch design. We characterize three mechanically spread glass fabrics and two common PCB dielectric materials. Repetitive traces with a period of 0.001 inch and several positions relative to the fabric grain direction produce maximum realizable skew and repetitive discontinuity resonances. These are used to identify glass style and positioning to aide in PCB characterization. Site: Blog: Facebook: Twitter: LinkedIn:
