Back plate assembly for motherboard

A method for securing a back plate to a motherboard, the motherboard defining a plurality of through apertures, the method comprising the steps of:

• a) providing a back plate comprising a plurality of posts extending upwardly therefrom;
• b) providing a plurality of clips, each of the clips defining a central cutout and forming a plurality of teeth extending toward a middle of the cutout;
• c) attaching the back plate to an underside of the motherboard, with the posts extending through the through apertures respectively;
• and
• d) placing the clips on top ends of the posts respectively and downwardly pushing the clips until the clips abut the motherboard and the teeth deformably retain the posts, thereby securely attaching the back plate to the motherboard.

An electronic device assembly comprising:

• a printed circuit board defining an electronic device mounting area with a plurality of through apertures thereabouts;
• a back plate assembly for attaching a heat dissipation assembly to the electronic device, said back plate assembly comprising:
• a back plate attached to an underside of said printed circuit board with a plurality of through holes in alignment with the corresponding through apertures, respectively;
• a plurality of discrete posts upwardly extending through both the through holes and the corresponding through apertures with heads abutting against the back plate;
• and
• a plurality of clips each defining a cutout in a middle thereof with a plurality of inwardly resilient teeth extending from a periphery thereof toward said cutout;
• wherein
• each of said clips is positioned on the printed circuit board opposite to the head of the corresponding clips, and each of the posts extends through the cut out of the corresponding clip and retained by the corresponding teeth so as to have the head and the corresponding clip sandwich the printed circuit board and the back plate therebetween.
