Ball grid array connector guidance, alignment, and strain relief

摘要

A strain relief device that includes a substrate component for mounting to a substrate prior to assembly of the strain relief device is disclosed. The substrate component is mounted on a substrate and a connector component that is attached to an electrical connector is press-fit or otherwise attached to the substrate component. The substrate component includes alignment elements, such as protrusions, that complement alignment elements, such as indentations, on the connector component. The alignment elements provide protection to the electrical connector against sheer forces as well as forces caused by CTE mismatches. The strain relief device may include an alignment pin received in an indentation formed in the connector component that extends such that, as the substrate component is mated with the connector component, the pin performs an alignment function as the pin is received in a corresponding indentation of the substrate component.
