Abstract

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.
