I am used to glue my drivers on the back side of the led mouting/thermal palte.

Idea behind is to get the heat from the driver away, too.

Just want to glue in the GDuP and noticed that they feature IC on both sides.

What side to glue to the sink?

The one with the conductor? So that this is also out of the way?

The other side would have a flatter IC mounted, which would be better for the positive spring.

any idea?
