Abstract
Abstract An electrical circuit has a substrate and a surface mount capacitor having a connector pad at each end. The substrate has two separate contact pads that are both soldered to the same connector pad on the capacitor. Two further contact pads on the substrate are soldered to the other connector pad on the capacitor. The contact pads on the substrate are connected to tracks that extend to plated-through holes and are electrically connected to one another at a point remote from the capacitor.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
132 words
An electrical assembly comprising a substrate and at least one surface mount capacitor, wherein the capacitor has a single connector pad at each end, wherein the substrate has two separate electrical contact pads and means electrically connecting both contact pads on the substrate to the same connector pad on the capacitor, the contact pads being otherwise electrically isolated from one another at the capacitor, wherein the substrate includes two tracks, wherein the two tracks extend away from the capacitor, the contact pads on the substrate being electrically connected with respective ones of the tracks, and wherein the substrate has two other electrical contact pads separate from one another that both make electrical connection to the other connector pad on the capacitor but are otherwise electrically isolated from one another at the capacitor.
Claim 2
Dependent Claim
132 words
An electrical assembly comprising a substrate and at least one surface mount capacitor, wherein the capacitor has a single connector pad at each end, wherein the substrate has two separate electrical contact pads and means electrically connecting both contact pads on the substrate to the same connector pad on the capacitor, the contact pads being otherwise electrically isolated from one another at the capacitor, wherein the substrate includes two tracks, wherein the two tracks extend away from the capacitor, the contact pads on the substrate being electrically connected with respective ones of the tracks, and wherein the substrate has two other electrical contact pads separate from one another that both make electrical connection to the other connector pad on the capacitor but are otherwise electrically isolated from one another at the capacitor.
Claim 3
Dependent Claim
23 words
An electrical assembly according to claim 1, wherein the tracks are electrically connected with one another at a point remote from the capacitor.
Claim 4
Dependent Claim
19 words
An electrical assembly according to claim 1, wherein the tracks extend to respective plated-through holes extending through the substrate.
Claim 5
Dependent Claim
28 words
An electrical assembly according to claim 1, wherein the assembly includes a solder connection between the connector pads on the capacitor and the contact pads on the substrate.
