Abstract:
1. A method for electrically connecting a first electronic device to a second electronic device, the first electronic device having a side edge and first and second faces generally perpendicular to the side edge, a first conductive area formed on the first face thereof, and a plated opening formed along the side edge of the first electronic device, the plated opening being electrically coupled to the first conductive area, the second electronic device having a first surface that includes a second conductive area, the method comprising the steps of: holding a solder mass having first and second ends in a carrier device that is non-wettable relative to solder, the carrier device having a body portion and at least one alignment member formed as a single piece with the body portion and extending therefrom, the alignment member configured to align the carrier device with respect to the first electronic device when positioned in a predetermined orientation and engaging the first electronic device, wherein the step of holding the solder mass in the carrier device comprises the steps of: orienting the carrier device with the alignment member engaging the first electronic device to achieve alignment of the carrier device in a direction perpendicular to the second face of the first electronic device and orienting the carrier device with respect to the side edge of the first electronic device such that the solder mass is adjacent to the plated opening; reflowing the solder mass to cause the solder mass to be deposited and securely held within the plated opening; removing the carrier device and leaving the solder mass within the plated opening along the side edge of the first electronic device; aligning the first electronic device with respect to the second electronic device with the first and second conductive areas adjacent to one another; and reflowing the deposited solder mass in the plated opening to form a filleted solder joint between the first and second conductive areas resulting in the first and second electronic devices being electrically connected.
