Abstract

This article describes methods of preventing the uncontrolled spread of uncured fluid encapsulant when applied to circuit-chips that are wire bonded onto flexible circuits. Use is made of formers to constrain, by surface tension, the wet encapsulant from encroaching onto undesired areas of the circuit layer.
