Abstract
An apparatus includes a printed circuit board having a set of layers and a set of barrels embedded within the set of layers. The apparatus further includes an electrical component having a component body and a set of pins which extends from the component body. The apparatus further includes a set of sleeves. Each sleeve defines a substantially conical shape. The set of sleeves provides electrical and thermal conductivity between the set of pins of the electrical component and the set of barrels of the printed circuit board.
Claims10
A device, comprising:
- a sleeve defining a substantially conical shape, the sleeve being arranged to provide electrical and thermal conductivity between a pin of an electrical component and a barrel of a printed circuit board when the sleeve is disposed between the pin of the electrical component and the barrel of the printed circuit board, the sleeve including a pin contacting end having a first outer diameter, and a barrel-contacting end having a second outer diameter, the sleeve tapering continuously in a same direction from the barrel-contacting end to the pin-contacting end wherein the first outer diameter is narrower than the second outer diameter, the sleeve further including a slit extending longitudinally thereon from the barrel-contacting end to the pin-contacting end.
An apparatus, comprising:
- a printed circuit board having a set of layers and a set of barrels embedded within the set of layers;
- an electrical component having a component body and a set of pins which extends from the component body;
- and
- a set of sleeves, each sleeve having a pin contacting end having a first inner diameter and a first outer diameter, and a barrel-contacting end having a second inner diameter and a second outer diameter, each sleeve defining a substantially conical shape that tapers continuously in a same direction from the barrel-contacting end to the pin-contacting end defined by that sleeve wherein the first inner diameter is narrower than the second inner diameter and the first outer diameter is narrower than the second outer diameter, each sleeve further including a slit extending longitudinally thereon from the barrel-contacting end to the pin-contacting end, and
- wherein the set of sleeves provides electrical and thermal conductivity between the set of pins of the electrical component and the set of barrels of the printed circuit board during use.
