Title: John Walvoord: Innovator in Laser Technology
Introduction
John Walvoord is a notable inventor based in Orlando, FL (US). He has made significant contributions to the field of laser technology, holding a total of 3 patents. His innovative approaches have led to advancements in automated soldering techniques and printed circuit board fabrication.
Latest Patents
One of Walvoord's latest patents is a laser soldering method. This automated soldering technique utilizes a laser to heat metallic components, ensuring robustness and reliability. The laser wavelength is specifically chosen based on the light absorption characteristics of the metallic components, with an example wavelength of about 825 nanometers. The method allows for a defocused beam spot that maintains uniform intensity across its area, enabling simultaneous soldering at multiple joint locations. Additionally, a camera is integrated coaxially with the laser beam, utilizing a dichroic prism to enhance the soldering process.
Another significant patent is related to an ablative process for printed circuit board technology. This method involves fabricating a printed circuit board on a doubly contoured or hemispherical substrate, such as a radome. A coherent light source, preferably an excimer laser, is employed to form a predetermined pattern on the substrate's surface. The process includes ablating elements into a resist coating or the metallized layer, followed by an etching technique to remove portions of the metallized layer.
