Electrical connector having thick film layers
An electrical connector electrically connects a first printed circuit board and a second printed circuit board, where the electrical connector includes: (a) an insulative housing; (b) a plurality of signal conductors, with at least a portion of each of the plurality of signal conductors disposed within the insulative housing; (c) each of the plurality of signal conductors having a first contact end, a second contact end and an intermediate portion therebetween; and (d) a passive circuit element electrically connected to the intermediate portion of each of the plurality of signal conductors, where the passive circuit element is housed in an insulative package and includes at least a capacitor or an inductor.
1. An electrical connector comprising:
an insulative housing having a surface;
a signal conductor disposed on the surface of said insulative housing, said signal conductor having a first signal conductor segment and a second signal conductor segment spatially separated from the first signal conductor segment; and,
a film layer disposed on at least a portion of said first signal conductor segment, at least a portion of said insulative housing, and at least a portion of said second signal conductor segment.
2. The electrical connector of claim 1 , wherein said film layer has a resistance.
3. The electrical connector of claim 1 , wherein the surface at said portion of said insulative housing is roughened or grooved to facilitate a connection between said film layer and said insulative housing.
4. The electrical connector of claim 1 , wherein a surface of said portions of the first and second signal conductor segments are roughened or grooved to facilitate a connection between said film layer and said portion of the first and second signal conductor segments.
5. The electrical connector of claim 1 , wherein said film layer comprises a thick film layer.
6. The electrical connector of claim 1 , further comprising a second film layer disposed on top of the film layer.
7. The electrical connector of claim 1 , wherein the film layer has a conductivity ranging from about 1:100 and about 1:1,000,000 of that of standard pure copper.
8. The electrical connector of claim 1 , wherein the film layer is a lossy dielectric, a lossy polymer resin, or a lossy magnetic material.
9. The electrical connector of claim 1 , wherein the film layer is a lossy magnetic material comprising one of a ferrite and a ferrite-particle-filed polymer resin matrix.
10. The electrical connector of claim 1 , wherein at least a portion of the film layer is etched to achieve a desired level of electrical resistance.
11. The electrical connector of claim 1 , wherein the film layer comprises a dielectric.
