Abstract:
1. A multi-layer printed wire board structure, comprising: a first conductive layer having a thickness between 25 and 50 um; a first insulative-coated conductive layer upon which said first conductive layer is disposed, wherein said first insulative-coated conductive layer has a thickness between 50 and 70 um; a second conductive layer upon which said first insulative-coated conductive layer is disposed, wherein said second conductive layer has a thickness between 25 and 50 um; a first insulative layer upon which said second conductive layer is disposed, wherein the first insulative layer has a thickness between 50 and 100 um; a third conductive layer upon which said first insulative layer is disposed, wherein the third conductive layer has a thickness between 12 and 19 um and wherein said third conductive layer is at least about 50 percent thinner than said first conductive layer and said second conductive layer; and a second insulative layer upon which said third conductive layer is disposed wherein the second insulative layer has a thickness between 50 and 100 um.
