Apparatus and methods for creating environmentally protective coating for integrated circuit assemblies

摘要

Example methods, apparatus, and products for creating an environmentally protective coating for integrated circuit assemblies are described herein. A preform plastic sheet is places over components of an integrated circuit such that during a reflow process, the preform plastic sheet melts to form a conformal coating over components of the integrated circuit assembly.

主权项

1. An integrated circuit assembly comprising:
an integrated circuit having a plurality of contact pads formed therein; a first preform sheet having holes formed therein corresponding to the location of the plurality of contact pads, the first preform being applied to a substrate side of the integrated circuit and configured to create a conformal coating during a reflow operation; a printed circuit board; a plurality of solder balls placed over the plurality of contact pads, the solder balls forming a connection between the integrated circuit and the printed circuit board during the reflow operation, wherein the first preform sheet melts during the reflow operation to form the conformal coating; and a second preform sheet being applied over the printed circuit board.
