Abstract
A printed circuit board (PCB) assembly is provided. The PCB assembly comprises a printed wiring board (PWB) and one or more electrical components mounted thereon. The PWB comprises a plurality of layers including conductive layers and insulative layers, where one or more of the insulative layers is a prepreg layer that is halogen-free; one or more slotted portions on a surface of the PWB, which are indented into the PWB; and one or more pads disposed on the surface of the PWB, which are paired with the one or more slotted portions. Each of the one or more electrical components is mounted on the surface of the PWB through a pair of a slotted portion and a pad.
Claims20
A printed circuit board (PCB) assembly comprising:
- a printed wiring board (PWB) comprising:
- a plurality of layers, the plurality of layers including conductive layers and insulative layers, wherein one or more of the insulative layers is a prepreg layer that is halogen-free;
- one or more slotted portions on a surface of the PWB, wherein each of the one or more slotted portions is indented into the PWB such that the slotted portion has fewer layers than the plurality of layers;
- and
- one or more pads disposed on the surface of the PWB, wherein the one or more pads is paired with a respective one slotted portion of the one or more slotted portions;
- and
- one or more electrical components disposed on the surface of the PWB, each of the one or more electrical components comprising only a first leg and a second leg that are positioned on opposite sides of the electrical component with a body of the electrical component positioned in-between the first leg and the second leg, wherein the first leg of each of the one or more electrical components is inserted into one slotted portion of the one or more slotted portions, and the second leg of the each of the one or more electrical components is mounted on one pad of the one or more pads that is paired with the one slotted portion.
A printed wiring board (PWB), comprising:
- a plurality of layers, the plurality of layers including conductive layers and insulative layers, wherein one or more of the insulative layers is a prepreg layer that is halogen-free;
- one or more slotted portions on a surface of the PWB, wherein each of the one or more slotted portions is indented into the PWB such that the slotted portion has fewer layers than the plurality of layers;
- and
- one or more pads disposed on the surface of the PWB, wherein the one or more pads is paired with a respective one slotted portion of the one or more slotted portions, wherein a slotted portion of the one or more slotted portions is configured to accept a first leg of an electrical component and a pad of the one or more pads is configured to accept a second leg of the electrical component, wherein the electrical component comprises only the first leg and the second leg, wherein the first leg and the second leg are positioned on opposite sides of the electrical component with a body of the electrical component positioned in-between the first leg and the second leg.
