Aric,
        Check out http://www.ppitapes.com, they have thermal management
tapes that are double sided aluminum with extremely high bond strength.
Just had the rep in last week, looks like a good product.

> Subject:      [TN] Heat Sink Assembly
>
> Hello Technetters,
>
> I am encountering several problems with a  heat sink assembly process.
> Currently, our heat sinks are hand placed onto cpus and other
> components
> using an epoxy dispenser ( automatic ) and a steady hand.
>
> The Problem:  The heat sinks are not seating properly, misaligned and
> uneven due to operator error.  Some of our products use clips and pins
> for heat sink placement, but several do not.  I know that this is an
> issue of board real estate that needs to be resolved between
> manufacturing and engineering, but until then I am looking for a
> solution.
>
> I want to take the human factor out of this heat sink placement so I
> can
> achieve the proper alignment and force to attach heat sinks to
> components.  They are to large and cumbersome for any high speed
> placement machine.
>
>
> If anyone has experienced this problem and has any suggestions, your
> response would be much appreciated.
