Abstract:
Disclosed herein are methods of fabricating a packaged radio-frequency (RF) device. The disclosed methods use a film during fabrication to control the distribution of an under-fill material between one or more components and a packaging substrate. The method includes mounting components to a first side of a packaging substrate and applying a film to a second side of a packaging substrate. The method also includes mounting a lower component to the second side of the packaging substrate and under-filling the lower component mounted on the second side of the packaging substrate with an under-filling agent. The method also includes removing the film on the second side of the packaging substrate and mounting solder balls to the second side of the packaging substrate after removal of the film.

Claim (Index 10):
A method for manufacturing packaged radio-frequency devices, the method comprising:\n applying a film to an underside of a 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, application of the film including covering the contact pad area with the film while leaving the die area uncovered by the film; after applying the film, mounting one or more lower components within the die area so that there is a gap between the one or more lower components and the packaging substrate; 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, removing the film from the underside of the packaging substrate.
