Abstract:
A daughter card adapter for receiving and supporting a daughter card for connection to a motherboard, the daughter card comprising contact areas along both sides of an edge of the card, the daughter card adapter comprising:a) a substrate having at least two parallel rows of laterally spaced, upstanding connectors having facing regions, the contact regions forming a first pattern matching that of the card's contact areas, b) a plurality of contact pads on a first surface of the substrate each adjacent and in contact with one of the upstanding connectors, c) a discrete solder deposit of solidified solder on each of the contact pads at a first location spaced from the adjacent upstanding connector, the closest part of the solder deposit being spaced from the contact region of the adjacent upstanding connector by a d) the upstanding connectors having at the contact regions insufficient solder for effecting a robust solder joint to contact areas on the daughter card when the adaptor and the supported daughter card are engaged and reflowed, e) each of the solidified solder deposits containing sufficient solder for effecting a robust solder joint between the upstanding connectors' contact regions and the contact areas on the daughter card when the adaptor and the engaged daughter card are heated to reflow temperature causing the solder deposit to melt and wick along the contact pad to the adjacent upstanding connector and then to flow up to its contact region.
