Abstract: The present disclosure generally relates to printed circuit boards or printed circuit board assemblies for fiber optic communications. In one example, an optoelectronic assembly may include a printed circuit board including a laser-roughened area, at least one optoelectronic component coupled to a surface of the printed circuit board, and an optical component attached to the printed circuit board. The coupling area may be defined by the optical component contacting the printed circuit board, and the laser-roughened area may be positioned entirely within the coupling area defined by the optical component contacting the printed circuit board.

Abstract: The present disclosure generally relates to printed circuit boards or printed circuit board assemblies for fiber optic communications. In one example, a method may include coupling at least one optoelectronic component to a surface of a printed circuit board. The method may include lasering the surface of the printed circuit board to form a laser-roughened area on the surface of the printed circuit board. The method may include coupling an optical component to the printed circuit board at the laser-roughened area on the surface of the printed circuit board.
