In some examples, an electronic package and methods for forming the electronic package are described. The electronic package can be formed by disposing an interposer on a surface of a substrate having a first pitch wiring density. The interposer can have a second pitch wiring density different from the first pitch wiring density. A layer of non-conductive film can be situated between the interposer and the surface of the substrate. A planarization process can be performed on a surface of the substrate. A solder resist patterning can be performed on the planarized surface the substrate. A solder reflow and coining process can be performed to form a layer of solder bumps on top of the planarized surface of the substrate. The interposer can provide bridge connection between at least two die disposed above the substrate. Solder bumps under the interposer electrically connect the substrate and the interposer.

A structure is provided that reduces the stress generated in a semiconductor device package during cooling subsequent to solder reflow operations for coupling semiconductor devices to a printed circuit board (PCB). Stress reduction is provided by coupling solder lands to metal-layer structures using traces on the PCB that are oriented approximately perpendicular to lines from an expansion neutral point associated with the package. In many cases, especially where the distribution of solder lands of the semiconductor device package are uniform, the expansion neutral point is in the center of the semiconductor device package. PCB traces having such an orientation experience reduced stress due to thermal-induced expansion and contraction as compared to traces having an orientation along a line to the expansion neutral point.
