A method for designing a carrier substrate includes configuring at least one die-attach location and one or more terminals that protrude from a surface of the carrier substrate so as to prevent adhesive material from contaminating connection surfaces thereof. The method may also include configuring the carrier substrate to include one or more recessed areas that laterally surround at least a portion of the die-attach location to receive excess adhesive.

Methods for designing carrier substrates with raised terminals

A solder mask for use on a carrier substrate includes a device-securing region positionable over at least a portion of a die-support location of the carrier substrate. Dams of the solder mask are positionable laterally adjacent to at least portions of the peripheries of corresponding terminals of the carrier substrate. A carrier substrate includes at least one die-attach location and one or more terminals that protrude from a surface of the carrier substrate so as to prevent adhesive material from contaminating connection surfaces thereof. The solder may be positioned or formed on the carrier substrate. The carrier substrate and solder mask may each include one or more recessed areas that laterally surround at least portions of their die-attach location and device-securing region, respectively, to receive excess adhesive.

Solder masks including dams for at least partially surrounding terminals of a carrier substrate and recessed areas positioned adjacent to the dams, and carrier substrates including such solder masks

The carrier substrate and solder mask may each include one or more recessed areas that laterally surround at least portions of their die-attach location and device-securing region, respectively, to receive some of the excess adhesive. Assemblies and packages including one or both of the carrier substrate and solder mask are also disclosed, as are assembly methods and methods for designing the carrier substrate and solder mask.
