Ball grid structure

摘要

An apparatus includes a contact grid array disposed on a substrate in a non-orthogonal row-column format with connection elements arranged in a hexagonal configuration. The contact grid array has an orientation based, at least in part, on an area available for the contact grid array on the substrate. A method to determine the orientation of the contact grid array includes identifying the area available for a contact grid array on a substrate and determining the orientation for the contact grid array based, at least in part, on the area available for the contact grid array on the substrate.

1. A method comprising:
identifying, with a processing device, an area available for a contact grid array on a substrate; determining, with the processing device, an orientation for the contact grid array including a non-orthogonal row-column format with multiple connection elements arranged in a hexagonal configuration, wherein the determined orientation includes at least a rotational orientation which is determined based, at least in part, on the area available for the contact grid array on the substrate and a required number of the connection elements in the area available; and implementing the determined orientation on the contact grid array.
