Abstract
A mount for connecting a heat sink to a PCB may include a threaded post extending along an axis, a first barrel adjacent to the post along an axis and having a larger axial cross-section than the post, and a threaded second barrel defining an opposite end of the mount from the post and having a larger axial cross-section than the first barrel.
Claims10
An electronic assembly, comprising;
- a printed circuit board (PCB) including a chip and PCB holes;
- a bolster plate including bolster plate holes, each bolster plate hole being concentrically aligned with one of the PCB holes;
- a heat sink including notches and a boss configured to contact the chip at an opposite side of the PCB from the bolster plate;
- load cells extending within the notches and each being concentrically aligned with one of the PCB holes and one of the bolster plate holes;
- and
- one or more mounts, each including:
- a post extending along an axis and engaged with one of the bolster plate holes;
- a first barrel axially adjacent to the post and having a larger axial cross-section than the post;
- a second barrel defining an axially opposite end of the mount from the post and engaged with one of the load cells;
- and
- a grip located axially between the first barrel and the second barrel,
- wherein the second barrel is configured to be received within a corresponding notch of the heat sink, and
- wherein a combined height of the boss and the chip exceeds a height of the grip.
10 more elements
A method of assembling electronic components, the method comprising:
- inserting a post of a mount through a printed circuit board (PCB) hole in a PCB and into a bolster plate hole in a bolster plate such that the post is threadingly engaged within the bolster plate hole, a portion of a first barrel axially extends from the post passes through the bolster hole and remaining portion of the first barrel extends through the PCB hole, and a grip extending axially from the first barrel bears against the PCB, wherein the PCB includes a chip;
- engaging a load cell of a heat sink with an opposite end of the mount from the post, wherein the heat sink includes a boss such that a combined height of the boss and the chip exceeds a height of the grip;
- and
- tightening the load cell to bring the chip on the PCB into abutment with the boss of the heat sink.
