Hi Everyone,

I am looking for a way to attach a heat sink to a BGA (45mm) without
adhesives, and without clipping directly onto the component, or a
socket. Has anyone seen some type of hook that can be placed onto the
board during surface mount, which could have a clip attach onto it?

If anyone knows of another type of mechanical attachment method that
does not require holes drilled in the board, a socket, or clipping onto
a component, I would like to hear about it.

We are reluctant to try adhesive tapes, since they are known to have bad
contact area. If someone knows of a double sided tape that has good
thermal properties, and forms good contact area, I would also like to
hear about it.

Thanks in advance for your time,

Remi
