Hermetic package with internal ground pads
View Patent ↗An optoelectronic hermetic package comprises a frame defining a hermetic boundary and an electrical feedthrough assembly on the frame. This electrical feedthrough assembly provides electrical connections between signal wire bond areas within the hermetic boundary to electrical contact areas outside the hermetic boundary. Additionally, according to the invention, ground wire bond pad areas are also provided within the hermetic boundary, the ground wire bond pad areas being electrically connected to each other and/or the frame or other ground plane.
1. An optoelectronic hermetic package, comprising:
a frame defining a hermetic boundary;
an electrical feedthrough assembly on the frame including: 1) electrical connections between signal wire bond areas within the hermetic boundary and electrical contact areas outside the hermetic boundary; and 2) ground wire bond areas within the hermetic boundary that are electrically connected to each other; and
conductive plugs extending between a top of the feedthrough assembly and the frame, the ground wire bond areas being located on a top of the conductive plugs.
2. A package as claimed in claim 1 , further comprising an array of leads extending from electrical contact areas away from the frame.
3. A package as claimed in claim 2 , wherein the leads extend laterally relative to the frame.
4. A package as claimed in claim 2 , wherein the leads are pins that extend vertically relative to the frame.
5. A package as claimed in claim 1 , wherein at least some of the ground wire bond areas are located between two of the signal wire bond areas on the feedthrough assembly.
6. A package as claimed in claim 1 , wherein the ground wire bond areas are interdigitated with signal wire bond areas.
7. An optoelectronic hermetic package, comprising:
a frame defining a hermetic boundary;
an electrical feedthrough assembly on the frame including: 1) electrical connections between signal wire bond areas within the hermetic boundary and electrical contact areas outside the hermetic boundary: and 2) ground wire bond areas within the hermetic boundary that are electrically connected to each other; and
conductive plugs extending between a top of the feedthrough assembly and a bus through the assembly, the ground wire bond areas being located on a top of the conductive plugs.
8. A package as claimed in claim 7 , further comprising an array of leads extending from electrical contact areas away from the frame.
9. A package as claimed in claim 8 , wherein the leads extend laterally relative to the frame.
10. A package as claimed in claim 8 , wherein the leads are pins that extend vertically relative to the frame.
11. A package as claimed in claim 7 , wherein at least some of the ground wire bond areas are located between two of the signal wire bond areas on the feedthrough assembly.
12. A package as claimed in claim 7 , wherein the ground wire bond areas are interdigitated with signal wire bond areas.
