Abstract
A circuit substrate utilizes buried edge connectors. The buried edge connectors are mechanically disposed within the edge of the substrate and have substantial thickness. The configuration and method for making the same provides relatively large edge connectors mechanically constrained in the edge of a circuit substrate.
Claims10
A circuit board, comprising:
- a substrate having a plurality of non-conductive layers stacked adjacent to each other that form a perimeter edge, wherein the substrate forms an ISR;
- a via portion formed in the perimeter edge;
- and
- a buried edge connector disposed in the via portion;
- wherein the via portion includes a mechanical mechanism to mechanically restrain the buried edge connector in the via portion.
2 more elements
A circuit board comprising:
- a plurality of non-conductive layers of a substrate which are stacked adjacent to each other;
- at least one via through the plurality of non-conductive layers filled with a conductive material;
- a cover layer covering the at least one via;
- and
- a bottom layer beneath the at least one via;
- wherein an exposed surface of the conductive material is substantially perpendicular relative to a major surface of the plurality of non-conductive layers;
- and
- wherein the substrate forms an ISR.
5 more elements
A circuit board sub-assembly comprising:
- a stack including a plurality of layers of a substrate;
- a via through the plurality of layers;
- a conductive material within the via;
- a cover layer covering the via and the conductive material;
- and
- a vent which extends through the cover layer and which is open to a top surface of the conductive material within the via and which does not extend through the via, wherein the vent allows any gases created in the via during curing of the substrate to be exhausted through the vent.
