Can you use conductive heat shrink tubing to basically "solder" a diode to ur drivers lead wires? just a curious question. cause if all your doing is making an electrical connection between diode, and driver lead wire. wouldnt it be the same thing as soldering the two together if you put the end of the diode pin and the lead wire in a conductive heat shrink tubing and shrink it around the two tightly?

thanks in advance to any insight.

I don't know any conductive heat tube.
Isn't it supposed to be an isolator anyway?

Also, shrink tubing doesnt hold mechanical stress.

You pull the wire and it comes loose, unlike a wire that's been soldered.

So you COULD make a connection, if the tube presses the two wires together,
but it wouldn't be a reliable connection. Not at all.

First, do you have a link for this product ?

Second, it depend from its resistance ..... if it's "conductive" like metal, it can be possible (also if not suggested), if instead it's "conductive" just like shielding plastics, then no, for sure no .....

and im just talking about sticking the diode pin and the drivers lead wire in the heat shrink, shrinking it, and if the two touch inside the heat shrink and the heat shrink doesnt give way or fall off since it should be tight on the two would it not work?

That would not form a reliable connection at all - just solder the wire to the diode pin.

You can add heatshrink tubing after that for mechanical stability and/or electrical insulation, but there is not way that two wires will connect reliablby by just heatshrinking them together without soldering.

^ Benm is right, this type of heatshrinking tube is made mainly for restore EMI - RFI shielding in coaxial cables, not for join power circuit wires ..... conductive layer is probably made with silver polymeric paint (the one used also in de-icing grids on cars glasses), and if so, it's conductive, but with a too much high resistance for give you any decent results .....

Also, if the diode loses it's connection for an instant your driver's capacitors will charge and dump a surge when it regains connection.... Which usually results in a diode's untimely death.
It isn't worth it, not even for a cheapy.

^ All good information. I would also add that a connection that comes loose even for a millisecond will kill the diode in an instant. Much better if you use high power magnification, a small amount of flux and a steady hand, free of espresso. Good luck to you! :)

^ What do you mean with "free of espresso" ?

grade material like silver heat sinks, silver is more conductive than copper and makes for use) plus I don't have to refill some tube with some liquid coolant all the time
