Hi again,
Yes exactly, and i did calculate the thermal properties and since the heating
was very much the same as with the purchased thermal epoxy i figure that
it was almost the same as the real stuff. I was very surprised to find this
out, because the stuff made for the job has aluminum in it for better conduction
and the run of the mill stuff was just that, any ol' stuff that wasnt made for
good thermal conduction. I guess i was expecting some usable results however,
or i wouldnt have applied the run of the mill stuff to the LED and heat sink,
but i never expected it to be so close to something that was actually made
for the job.
It's too bad i could not use the exact same LED and heatsink, although i used
another LED of the exact part number and the same exact size and make of
heatsink, so i feel that the two results were comparable.
What i did was apply the epoxy, then squished it down real good and moved
it around, sliding it back and forth a little, to get the epoxy layer as thin
as absolutely possible. I thought that just about anything should work
pretty good if it is kept THAT thin
Luckily, it worked out, otherwise
i would have had to chisel the LED off and use actual thermally conductive
epoxy.
On a related subject, i have read about the electrically conductive paints
or pastes (whatever they are) for fixing or even making conductors.
I havent actually tried any ever however, and they are a bit expensive.
Perhaps you've had some experience, or maybe i should make another
thread about this? A friend asks me about this too.
