Title: The Innovations of Erich H. Selna

Introduction

Erich H. Selna is a notable inventor based in Mountain View, CA (US). He has made significant contributions to the field of technology, particularly in the development of integrated circuit (IC) substrates and memory modules. With a total of 6 patents to his name, Selna's work has had a lasting impact on the industry.

Latest Patents

Among his latest patents is the "Hold-down collar for attachment of IC substrates and elastomeric." This invention involves a land grid array package or a ball grid array package that is electrically connected by an elastomeric layer. The layer contains alternating elements of conductive and non-conductive silicone, which connects to a printed wire board or motherboard. The hold-down collar engages the peripheral edges of the package and snaps into holes in the board, creating pressure on the elastomeric layer. This pressure compresses the layer, establishing electrical paths between exposed lands or conductive elements on the package and the wiring board. In one embodiment, solder balls adhere to the exposed conductive elements on the bottom of the package.

Another significant patent is the "Single in-line memory module having on-board regulation circuits." This invention discloses a single in-line memory module (SIMM) that includes on-board regulation circuits. The module features a plurality of inputs, including a first reference voltage signal. The memory elements are arranged to form a datapath with a predetermined width and operate at a second reference voltage signal, which differs from the first. On-board regulation circuits translate the first reference voltage signal into the second, allowing the memory elements to utilize the first reference voltage signal effectively.
