Micro-structured substrate adhesive application procedure uses polymer or metal mesh screen through which an adhesive is applied by a scraper

摘要

A micro-structured substrate adhesive application procedure using a polymer or metal mesh screen through which an adhesive is applied by a scraper, is new. An adhesive application procedure using a mesh screen (10) which is laid over the raised zones (6) of the substrate (2), and through which adhesive (12) is applied with the aid of a tool such as a scraper (16). This enables a film (20) of adhesive droplets to reach the raised zones without coating the cavities (8) between them when the screen is removed. A second substrate can then be applied to the first so that it sticks to the raised zones. The substrates are made of glass, silicon or polymer, and the cavities can be used to contain biological sensors.
