Abstract:
1. A method for coating an optoelectronic chip-on-board module comprising a flat substrate populated with at least one optoelectronic component, the method comprising the following steps: a) preheating the flat substrate to be coated to a first temperature; b) applying on the preheated substrate a dam that encloses at least a partial surface area of the flat substrate to be coated and partially covers a plurality of lateral surfaces and a portion of a top surface of the at least one optoelectronic component, wherein the dam comprises a first, heat-curable, highly reactive first silicone that is cured at the first temperature and is transparent to light that emits from the at least one optoelectronic component; c) filling the at least partial surface area enclosed by the dam on the flat substrate with a liquid second silicone; and d) curing the second silicone to form a transparent, UV-resistant, and temperature-resistant coating.
