Abstract

Characteristic impedance control on flexible circuits is a requirement for successful implementation in high speed applications. However, due to manufacturing, process and cost limitations associated with flexible environments, standard impedance control processes can affect yield and piece cost. This document describes a method by which entire panels of flexible circuits can be screened for proper characteristic impedance without adversely affecting yield, parts-per-panel and cost.
