Adjusting sizes of connectors of package components

摘要

A device includes a plurality of connectors on a top surface of a package component. The plurality of connectors includes a first connector having a first lateral dimension, and a second connector having a second lateral dimension. The second lateral dimension is greater than the first lateral dimension. The first and the second lateral dimensions are measured in directions parallel to a major surface of the package component.

1. A device comprising:
a plurality of connectors on a top surface of a package component, wherein the plurality of connectors comprises:
a first plurality of connectors in a first local surface region of the package component, wherein each of the first plurality of connectors has a first lateral dimension, wherein the first local surface region has a first connector density equal to a ratio of a total top-view area of all connectors in the first local surface region to a total top-view area of the first local surface region; anda second plurality of connectors in a second local surface region of the package component, wherein each of the second plurality of connectors has a second lateral dimension different from the first lateral dimension, with the first and the second lateral dimensions measured in directions parallel to a major surface of the package component, wherein the second local surface region has a second connector density equal to a ratio of a total top-view area of all connectors in the second local surface region to a total top-view area of the second local surface region, and wherein the first connector density is substantially equal to the second connector density.
