Design Considerations for Flush Circuits

Abstract

A flush circuit is one in which the surface of the conductor is within a minute fraction of an inch from the surface of the substrate itself. Flush circuits are produced by adding epoxy to the surface of a previously etched PCB by one of two primary methods. This article discusses the flushing process, its basic applications, and the ways to design flush PCB's for high reliability and low cost.
