Claims
- 1. A mold tool for an optoelectronic device comprising:
a first mold piece having a surface that defines a first cavity and an aperture within said first cavity; a second mold piece having a surface which defines a second cavity, said first cavity cooperating with said second cavity to form a molding compound into a predetermined shape; and an ejector pin having a contoured tip, said pin movably located within said aperture between a first position retracted within said aperture so that said tip constitutes an integral portion of said first cavity and a second position extended from said aperture so that said ejector pin facilitates removal of said compound from said first cavity, wherein said predetermined shape is at least partially defined by said contoured tip.
- 2. The mold tool of claim 1, wherein said first cavity forms a surface for the transmission of light.
- 3. The mold tool of claim 2, wherein said tip is contoured to create a lens in said surface.
- 4. The mold tool of claim 3, wherein said tip comprises a flat, circular portion corresponding to a substantially flat surface of said lens.
- 5. The mold tool of claim 4, wherein said tip further comprises a curved portion blending into said flat, circular portion, said curved portion corresponding to an arcuate edge surface of said lens.
- 6. The mold tool of claim 3, wherein said tip comprises a spherical dome portion corresponding to a spherical surface element of said lens.
- 7. The mold tool of claim 3, wherein said tip has a taper on an outer diameter corresponding to a sidewall disposed around said lens.
