Abstract

A bracket assembly includes a bracket which readily and easily couples with a printed circuit board. The bracket includes at least one tab assembly foldably attached with a support flange for supporting the printed circuit board. The bracket also includes an outer flange which is coupled with the computer chassis. Alignment apertures on the support flange and the printed circuit board facilitate the alignment of the printed circuit board, and allow for rework of the printed circuit board. Each tab assembly is adapted to frictionally engage with corresponding features on the printed circuit board.

Claims

1. A method comprising:

placing a circuit board on a support flange of a bracket assembly, the bracket assembly including at least one assembly tab;

folding the at least one assembly tab over the circuit board toward the support flange, where the at least one assembly tab is folded from a first unfolded position to a second folded position;

disposing at least a portion of the at least one assembly tab into a portion of the circuit board in the second folded position, wherein at least a portion of the at least one assembly tab is substantially parallel to the support flange; and

folding two or more assembly tabs over the circuit board.

2. The method as recited in claim 1, wherein the two or more assembly tabs are folded over the circuit board simultaneously.

3. The method as recited in claim 1, further comprising coupling the at least one assembly tab with the support flange.

4. The method as recited in claim 3, further comprising disposing the at least one assembly tab in a portion of the support flange.

5. The method as recited in claim 1, further comprising aligning features of the circuit board with alignment features on the support flange.

6. A method for forming a bracket assembly, the method comprising:

placing a circuit board directly adjacent to a bracket, the bracket including a support flange;

deforming at least a portion of the bracket over the circuit board;

coupling the at least one portion of the bracket within coupling features of the support flange; and

folding two or more assembly tabs over the circuit board.

7. The method as recited in claim 6, wherein the two or more assembly tabs are folded over the circuit board simultaneously.

8. The method as recited in claim 6, wherein coupling the at least one portion of the bracket includes coupling the at least one portion of the bracket within one or more apertures formed in the support flange.

9. The method as recited in claim 6, wherein coupling the at least one portion of the bracket includes coupling a slender flexible finger with the support flange.

10. The method as recited in claim 6, wherein deforming at least the portion of the bracket includes deforming the portion over a side edge of the circuit board.

11. The method as recited in claim 6, further comprising aligning features of the circuit board with alignment features on the support flange.

12. The method as recited in claim 6, further comprising electrically grounding the circuit board to the bracket.
