  • Patent number: 9142481
    Abstract: A method of manufacture of an integrated circuit packaging system includes: providing a substrate; attaching an integrated circuit to the substrate; molding an encapsulation directly on the integrated circuit and the substrate; forming a trench in the encapsulation having a trench bottom surface and surrounding the integrated circuit; and mounting a heatsink having a heatsink rim over the integrated circuit with the heatsink rim within the trench and the heatsink electrically isolated from the substrate.
    Type: Grant
    Filed: June 5, 2012
    Date of Patent: September 22, 2015

  • Patent number: 9125332
    Abstract: A semiconductor package includes a semiconductor die with a plurality of solder bumps formed on bump pads. A substrate has a plurality of contact pads each with an exposed sidewall. A solder resist is disposed opening over at least a portion of each contact pad. The solder bumps are reflowed to metallurgically and electrically connect to the contact pads. Each contact pad is sized according to a design rule defined by SRO+2*SRR?2X, where SRO is the solder resist opening, SRR is a solder registration for the manufacturing process, and X is a function of a thickness of the exposed sidewall of the contact pad. The value of X ranges from 5 to 20 microns. The solder bump wets the exposed sidewall of the contact pad and substantially fills an area adjacent to the exposed sidewall. The contact pad can be made circular, rectangular, or donut-shaped.
