    Abstract: Systems and methods according to embodiments of the invention enable flip chip packaging using high density routing while minimizing the thickness and layer count of the flip chip package. By using a photoresist layer to create very fine traces on a metallic base layer, embodiments of the present invention combine advantages of leadframe substrates and laminate substrates by supporting high-density routing while minimizing layer count and manufacturing cost. Additionally, the use of raised metallic pads in a routing layer enables embodiments of the present invention to include highly compact traces that pass over IC die bond pad connection sites without directly coupling to these bond IC die bond pad connection sites. Further, embodiments of the present invention can support multiple thin routing layers without the need for organic (e.g., laminate) material separating these routing layers.

  • Patent number: 8310035
    Abstract: Even when only one of semiconductor packages mounted by carrying out infrared reflow is defective, it is required to carry out infrared reflow again to dismount this defective semiconductor package from a mounting board. At this time, stress of heat is also applied to the other non-defective semiconductor packages. For this reason, if infrared reflow is carried out beyond a number of times of infrared reflow specified for non-defective semiconductor packages, the operation of each non-defective semiconductor package cannot be assured. In this case, it is inevitable to discard the semiconductor packages together with the mounting board. To solve this problem, a magnetic material is passed through a hole penetrating a protection member and a package board and the relevant semiconductor package is fixed over a mounting board by this magnetic material. To supply power to the semiconductor package, electromagnetic induction by coils provided in the package board and the mounting board is used.
