Title: The Innovative Contributions of Kelly Rennels

Introduction

Kelly Rennels is a notable inventor based in Mt. Holly Springs, PA (US). She has made significant contributions to the field of printed circuit board production, holding two patents that showcase her innovative approach to materials and processes.

Latest Patents

Rennels' latest patents focus on the development of base webs for printed circuit board production using the foam process and acrylic fibers. These patents describe a printed circuit board made from at least one non-woven sheet or web layer that comprises at least 50% by weight acrylic fibers. The remaining balance consists of substantially electrically non-conductive fibers, filler, and binder. The sheet or web is preferably produced using the foam process and may contain 60-80% straight polyacrylonitrile fibers and 40-20% fibrillated (pulp) fibers. The web or sheet is compressed by thermal calendering, achieving a density of about 0.1-1 grams per cubic centimeter, with a basis weight ranging from 20-120 grams per square meter. Additionally, the web or sheet may include 1-40% of substantially electrically non-conductive organic or inorganic binder, or it may be substantially binder-free. The printed circuit board created using these non-woven webs or sheets demonstrates improved properties compared to traditional woven glass and non-woven aramid products, including enhanced fiber consolidation, simplified board construction, and improved MD/CD ratio and stability.
