heat dissipation method - Page 2

JMFahey · 15th February 2013, 10:59 PM

Well, I recently have been getting incredibly consistent thin micas.
But if now and then I get a thicker one, I save it in a little separate bag ... which I keep in the larger "bulk" bag anyway.
Whenever I have 20 or 30 (or more) "thick" ones, whenever I am bored doing nothing , as in waiting for my coffee to brew, I split them in half.
Easy to do once you practice a little.
A few (very few thanks God) split unevenly , meaning a thicker half and a too thin one, which sometimes cracks.
To the junkbin it goes.

Mount devices to copper heat spreaders that are electrically insulated from the main heatsink.

Do you have an example to show us?

In the lab we use sapphire plates due to their excellent electrical insulation properties while still having high thermal conductivity - but maybe no realistic DIY option...

The copper added to the semi increases the contact area if it is bigger and also is an immediate heatsink without the insulator, so more effective.

See my triamp. Look near the top capacitor on the left.
