Claim of US Patent No. 9,907,209

1. An assembly, comprising:
a substrate including at least two anchors;
an electronic device mounted to the substrate;
a heat sink with a plate having a plurality of fins extending from a first surface of the plate, the fins defining a channel
along the first surface; and

a retaining clip, the retaining clip including a middle section and a first end section and a second end section on either
side of the middle section,

the middle section fitting within the channel and engaging the first surface of the heat sink to hold a second surface of
the heat sink in thermal contact with the electronic device, wherein the middle section further includes a portion extending
above the first surface, within the channel, to limit rotation of the heat sink,

each of the first and second end sections including:
a pivot end between the middle section and one of the first end section or the second end section,
a distal end to engage one of the at least two anchors,
a first leg adjacent to the distal end,
a second leg adjacent to a pivot end, and
a bend between the first leg and the second leg, the bend forming an acute angle that opens toward the substrate when the
distal end is engaged with one of the at least two anchors, the bend being located to form a moment arm from the pivot end
to the bend, wherein the moment arm is longer than a distance between the distal end and the pivot end.
