Title: Leo Roos - Innovator in Solder Mask Technology
Introduction
Leo Roos, a prolific inventor based in Laguna Beach, California, has made significant contributions to the technology of solder masks, with a total of nine patents to his name. His innovations are pivotal in advancing the manufacturing processes of printed circuit boards.
Latest Patents
Roos’s latest patents include a pioneering dry film photoresist for forming a conformable mask. This dry film comprises a cover sheet, a photoimageable composition layer that can be cured to create a solder mask, and a top coat that provides protection. The film is expertly applied to the surface of a printed circuit board, where a minor portion of the photoimageable composition layer is initially tacked. After peeling off the cover sheet, heat and vacuum are employed to ensure that the layer conforms to the contours of the circuit board. Once the application process is complete, the photoimageable composition layer is exposed to patterned actinic radiation, developed, and cured to produce a durable solder mask.
Another notable invention is a method of applying a conforming mask to a printed circuit board. Similar to the previous patent, this method uses a dry film that includes a cover sheet, a photoimageable composition layer, and a protective top coat. With the application of heat, vacuum, and mechanical pressure, the composition layer is partially laminated to the board's surface. After the cover sheet is removed, the layer conforms fully to the board's contours before being cooled. This innovative process results in a hard, permanent solder mask that enhances the production quality of printed circuit boards.
