Abstract:
Described herein methods of manufacturing dual-sided packaged electronic modules that control the distribution of an under-fill material between one or more components and a packaging substrate. The disclosed technologies include under-filling one or more components and deflashing a portion of the under-fill to remove under-fill material prior to attaching solder balls. The deflashing step removes a thin layer of under-fill material that may have coated contact pads for the ball grid array. Because the solder balls are not present during under-fill, there is little capillary action drawing material away from the components being under-filled. This can reduce the frequency of voids under the components being under-filled. Accordingly, the disclosed technologies control under-fill for dual-sided ball grid array packages using under-fill deflash prior to attaching solder balls of the ball grid array.

Claim (Index 8):
A method for manufacturing packaged radio-frequency devices, the method comprising:\n mounting one or more lower components on an underside of a packaging substrate so that there is a gap between the one or more lower components and the packaging substrate, the packaging substrate having an upper side with one or more upper components mounted thereto, the underside of the packaging substrate having a die area and a contact pad area having a plurality of contact pads for through-mold connections; after mounting the one or more lower components, depositing an under-fill material on the packaging substrate so that the under-fill material penetrates into the gap; and after depositing the under-fill material, deflashing a portion of the under-fill material that covers one or more targeted areas.
