Abstract:
1. A semiconductor device comprising: an optical semiconductor leaving an imaging area; a PCB having a top, a bottom, and an opening that extends from the top of the PCB to the bottom of the PCB, the optical semiconductor being mounted directly on the top surface of the PCB using one or more electrical contacts formed between the optical semiconductor and the top surface of the PCB, the optical semiconductor being mounted such that the imaging area is facing the opening and substantially unobstructed by the PCB; an underfill material that is dispensed in between the optical semiconductor and the PCB; and a B-stageable thermosetting resin barrier in between the optical semiconductor and the PCB, such that the barrier surrounds the opening in the top of the PCB and is adapted to prevent the underfill material from entering the opening.
