Abstract:
A method of converting a land grid array (LGA) module to a ball grid array (BGA) module by removing and oxidizing portions of the LGA conductive pad features on the upper surface of the LGA module. A BGA solder ball is deposited on the remaining portion of the conductive feature of the LGA module, with subsequent reflowing of the BGA solder ball. By modifying the LGA module to support a BGA structure, excessive heat generated by components placed on the modified LGA pad can be conducted through the BGA structure and into the element on which the LGA module is attached, such as a PCB.

A contact structure and assembly and a method for manufacturing the same for a microelectronics device includes first and second electrically conductive contacts being helically shaped. A carrier element is attached to and positioned between the first and second contacts. The first and second contacts are in electrical communication with each other, and the first and second contacts are in a mirror image relationship with each other.
