    Heatsink Fin to Base Thermal Resistance- Epoxy vs Braze

    They allow epoxy if it has been tested to show chemical resistance to jet fuel, chemical solvents, etc. This thread is regarding a thermal / heat transfer question, the other is a materials compatibility issue. They are fundamentally different and each one lends itself to a different forum...

    Heatsink Fin Attachment - Epoxy vs Braze

    Mike - They are ok with using epoxy if it has been tested to verify its ability to withstand chemical attack. I know of at least one epoxy used to bond heat sink fins on a Navy ship but it isn't thermally conductive. None of the thermally conductive epoxies that I've come across have been...

    Heatsink Fin to Base Thermal Resistance- Epoxy vs Braze

    IRstuff - I did not cross post. The two threads I started are quite different.

    Heatsink Fin to Base Thermal Resistance- Epoxy vs Braze

    I'm investigating the trade-offs between bonding fins to a heatsink using thermally conductive epoxy or brazing. Epoxy is desirable because of cost but I need to quantify the impact on the thermal resistance of the fin-base interface. I can think of some basic hand calculations but I was...

    Heatsink Fin Attachment - Epoxy vs Braze

    I'm investigating the trade-offs between bonding fins to a heatsink using thermally conductive epoxy or brazing. The epoxy is desirable because of cost but I need to verify that it can withstand exposure to jet fuel and chemical solvents on a Navy ship. I have a few epoxies that claim...
