Laminated printed circuit board with over-molded light guide

A laminated printed circuit board with over-molded light guide, comprising:

• a printed circuit board having electronic components mounted on a first face of the printed circuit board, and a bore extending through the printed circuit board;
• a light emitting diode mounted on the first face proximate to the bore;
• an opaque film fixed onto a second face of the printed circuit board, the opaque film creating an end wall of the bore;
• and
• a light transmissive polymeric material applied over each of the electronic components, the light emitting diode and a portion of the first face of the printed circuit board, a portion of the polymeric material extending into the bore and contacting the opaque film defining the end wall of the bore to create a light guide for transmitting light from the light emitting diode through the bore.

A laminated printed circuit board with over-molded light guide, comprising:

• a printed circuit board of a metal material having electronic components mounted on a first face of the printed circuit board connected to first electrical traces printed on the first face, and a bore extending through the printed circuit board;
• a light emitting diode mounted on the first face proximate to the bore and connected to the first electrical traces;
• a light transmissive polymeric material overmolded onto the electronic components, the light emitting diode and at least a portion of the first face of the printed circuit board, a portion of the light transmissive polymeric material extending into the bore and contacting an opaque film having a translucent portion therein, the opaque film defining an end wall of the bore to create a light guide for transmitting light from the emitting diode through the bore and to the translucent portion of the opaque film;
• and
• a polymeric material opaque layer positioned about a perimeter of the printed circuit board and a perimeter of the opaque film, and applied onto a surface of the light transmissive polymeric material extending freely beyond the opaque film.
