Flexdrive Driver Heatsink for Continuous driver duty cycle @ 1.5A

The nice thing about how I set up the coin sinks is you can adjust the pot anytime you want without needing to remove the driver.;)

That is the way to go if ones host can allow it :)
 





No thermal paste is different stuff this is two part thermal adhesive.

Just do a search on Ebay where every your are for Arctic Silver two part thermal adhesive 7G the one with 99% micronized silver. I actually fond a computer store locally that sells it for like $5-6 compared to the $11 on ebay.:beer:

This is ok?
 
Do you cover the whole bottom in this stuff DTR? Or just the IC Chips? I have heard about shorting....

its non conductive so covering the whole thing is fine and will work better...assuming you use the arctic silver adhesive

You don't spread the adhesive on the driver. Lightly apply some to the surface that you are sinking the driver to. Then let the driver set for 15 minutes without moving it. Also make sure the chips are flat on the surface you are sinking to.:beer:
 
Jay is dead on as usual.;)

The main purpose of the coin is to move the heat to the host body. Previous heatsinks that I have used did not have contact with the host and just built up the heat until the driver overheated. Granted that one took me from a 30 second max with no heatsink to around 3 minutes.


Old way with no contact to the pill. Gives around a 3 minute run.

New way. Continuous duty cycle. Solid contact with the pill.

It would be even better to do it your way, but have an additional driver heatsink inside the pill ;)

The pill and host body is the driver heatsink. There is not much you can or would ever need to do to make it better.;)
 
It's amazing that a simple coin is thick enough to heat sink the driver for that long of a time!
I'm sure coins make excellent heat sinks, and btw, I have access to many many coins of all sizes in 3 grades of silver, silver is one of the best heat sink metals, these coins are as follows: 99.9% or "FINE silver, sterling or 92.5% silver and "Coin silver which is 90% silver by weight. Also the Kennedy Half dollars from 1975 to 1980 are 40% silver. These 1964 and earlier dates are all 90% silver as are these date US 1/2 dollars, dimes and quarters. ;) -Glenn

I have a large bag of coins that are all a high percentage of copper or silver in varing sizes just for this purpose. Just remember the reason for the coin is to provide a flat surface to adhear the driver to and transfer the heat to the real heatsink which is the host.;)
