I have a heatsink I made for a TO transistor but I want to glue little tubes into it so that the leads are kept away from the copper.
I can slide tubing over the leads cut to lenght but I thought a better solution would be to actually glue something in there.
What is the best material that adheres to glue the best that can be bought in a rod stock (and drilled) or tube form that I can use for this purpose?
I have teflon super glue primer etc, but its not super necessary here. I thought I can optimize the design by choosing which material will glue the easiest, not necessarily the best insulator.
Part of me thinks that maybe some kinda rough ceramic would be best? The glue should have really good adhesion to alumina I think. But some sort of plastic would be OK too.
These typically annoy the shit out of me and break circuits when the insulator slips out, so I want it in there really good.
Maybe filling them with epoxy and drilling it out would be the best way actually.
