Patent ID: 7534320

Claim:
A method of bonding a substrate into a channel of a radio-frequency module, comprising: (a) placing an adhesive film on a bottom surface of the channel, the channel having at least two sidewalls; (b) placing a substrate on the adhesive film, the substrate having a height smaller than the depth of the channels; (c) inserting a press pad into the channel and over the substrate, the press pad including a lower abutting surface for abutting the substrate, and an elongated pad body having a pair of vertical protrusions extending laterally from the pad body on opposing sides thereof; (d) maintaining the vertical protrusions in slidable engagement with an adjacent sidewall of the channel as the press pad vertically translates in the channel thereby maintaining the lower abutting surface parallel to the substrate; (e) applying pressure to the press pad so that the lower abutting surface abuts the substrate thereby promoting the bonding between the substrate, the adhesive film, and the bottom surface of the channel; and (f) curing the adhesive film under pressure.
