| May 3, 2022 at 17:25 | comment | added | Criticizing Israel not allowed | @A.H.Z. something like this: aliexpress.com/item/33034978192.html that would hold the two parts together while the glue sets. It is a tool that is often used when gluing things together. It might not be necessary - you could also put something heavy on top. The purpose would be to squeeze the heatsink and the transistor together tightly, to minimize the amount of space filled by glue. | |

| May 3, 2022 at 16:19 | comment | added | Criticizing Israel not allowed | @A.H.Z Could just try it and see, of course. Don't forget the thermal paste to fill air gaps. I'm not sure how you could get a better contact, other than perhaps using thermal glue, if such a thing exists, and clamping it tightly with a clamp while the glue sets. | |
| May 3, 2022 at 15:21 | comment | added | A.H.Z | Shorts and mechanical stresses aren't really an issue; I am only going to mount one MOSFET (as an active load) unto the heatsink. It has come to my attention that drilling a single hole to mount the transistor using a vias might not be a good option, in that case, is there any better way to clamp it? | |
