Title: Innovations of James L Jellison
Introduction
James L Jellison is a notable inventor based in Albuquerque, NM (US). He has made significant contributions to the field of engineering, particularly in the area of welding technology. With a total of 4 patents to his name, Jellison's work has had a considerable impact on various industries.
Latest Patents
One of Jellison's latest patents is the "Optical penetration sensor for pulsed laser welding." This innovative apparatus and method determine the penetration of the weld pool created from pulsed laser welding. It utilizes an optical technique to monitor the weld vaporization plume velocity, allowing for accurate depth determination of the weld. A light source directs a beam through the vaporization plume above the weld pool, where the plume alters the intensity of the beam, enabling the assessment of the plume's velocity.
Another significant patent is the "Solderability test system." This new test method quantifies capillary flow solderability on a printed wiring board surface finish. The test is based on solder flow from a pad onto narrow strips or lines. Jellison developed a test procedure and video image analysis technique for conducting the test and evaluating the data. Feasibility tests revealed that the wetted distance was sensitive to the ratio of pad radius to line width, solder volume, and flux predry time.
Career Highlights
Throughout his career, Jellison has worked with prominent organizations, including Sandia Corporation and the United States of America as represented by the Department of Energy. His experience in these institutions has allowed him to refine his skills and contribute to groundbreaking projects.
