Depth-adaptive mechanism for ball grid array dipping
Abstract:
This document describes systems and techniques of a depth-adaptive mechanism for ball grid array dipping. In an aspect, a depth-adaptive mechanism having a tensioned mesh is positioned in a reservoir filled with flux. When solder balls of an integrated circuit component are dipped into the reservoir of flux, the solder balls are pressed up against the tensioned mesh. The tensioned mesh is configured to, first, elastically deform under the downward force applied by the solder balls and, second, provide an equal and opposite pushing force in order to facilitate solder ball extraction. In so doing, the solder balls of an integrated circuit component can be more easily extracted from flux when deep ball grid array dipping is performed.
