摘要:
Disclosed is a connector structure on a substrate which includes at least one first solder portion on the surface of the substrate; at least one second solder portion connected to each of the at least one first solder portions; and an epoxy layer disposed about the at least one first and second solder portions in such a manner as to cover the first solder portion and contact, but not cover, the second solder portion.Also disclosed is a connector structure on a substrate which includes at least one first solder portion on the surface of said substrate; at least one second solder ball portion connected to the at least one first solder portions; wherein the melting point of the second solder ball portion is relatively higher than that of the first solder portion.Finally, disclosed is a method of testing the solderability of the above structures.
摘要:
An electronic component package comprising a substrate having at least one die-receiving cavity formed therein, the cavity being defined by a die-receiving surface and an inner sidewall having a terraced contour, the substrate having an exterior surface bordering the cavity perimeter, the inner sidewall extending between the die-receiving surface and the substrate exterior surface, and at least one capacitor positioned completely within the cavity and mounted to the terraced contour of the inner sidewall.
