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.

Techniques for providing electrical and thermal conductivity between electrical components and printed circuit boards using sleeves defining substantially conical shapes

A device, apparatus and printed circuit board assembly for removably coupling an electrical component with a PCB are described, which provides adequate electromechanical capability, is relatively insensitive to related heating, component removability, replacability and reworkability while minimizing wear and the possibility of resizing and damage. The device includes a sleeve for coupling with a component pin, which encloses the pin and further couples to a conductive barrel interconnecting multiple PCB layers. The sleeve conforms upon insertion within the barrel to its contour. A flange at an end of the sleeve deters over-insertion. The coupling so formed can be gas-tight.

Device, apparatus, method and assembly for coupling an electrical component with a circuit board

A multi-layer printed circuit board (PCB) has a plated through hole for receiving a pin of a component. The plated through hole passes through all layers of the PCB and includes a first conductive portion on a first surface of the PCB and a second conductive portion on a second surface of the PCB. At least one layer of the PCB includes a planar conductive material disposed over a planar insulating material. The conductive material surrounds the plated through hole and is separated therefrom by a gap.

Power connection structure

A printed circuit board (PCB) has at least a first surface. A patterned electrically and thermally conductive layer is disposed on the first surface. A surface mount device (SMD) is disposed on an area of the layer and is attached thereto with solder. Heatsink elements, each including at least one flat surface, are placed by a pick and place assembly robot and permanently attached to the area with solder.
