Title: Donato Casati: Innovator in Surface Analysis Technologies
Introduction
Donato Casati is a notable inventor based in Merate, Italy, recognized for his contributions to surface analysis technologies. With a total of five patents to his name, Casati has made significant advancements in understanding the adhesion properties of surfaces and the cleanliness of substrate surfaces.
Latest Patents
Among his latest patents, Casati has developed a method and apparatus for estimating the adhesion properties of a surface of an article. This innovative approach involves holding the article with the surface facing downwards and placing a droplet of liquid against it. The volume of the droplet is incremented until it reaches a critical weight, at which point some of the liquid drops due to gravity. The critical weight serves as an indicator of the mutual adhesion forces between the liquid and the surface. By maintaining constant characteristics of the liquid, an immediate evaluation of the surface's adhesiveness can be obtained by comparing the measured critical weight with experimental results.
Another significant patent focuses on estimating the degree of cleanliness of a substrate surface, particularly in the manufacturing of electronic components. This method measures the surface wettability by depositing a droplet of test liquid on the substrate and measuring the speed of evaporation. The evaporation speed is proportional to the droplet's surface area, which depends on the substrate's wettability. A good surface wettability indicates a clean surface, which is crucial for electronic manufacturing.
