Not really. Copper is around 350W/m.K while even silver solder is below 100W/m.K IIRC. Still far better than most heatsinks tho.
And those metal pads.. they are very expensive right?
Ok, those metalpads probably don’t count as “budget” stuff.
But on ebay you can find them at a “reasonable” price, like 3x CPU pad for less than 12 euros (roughly $16).
I believe a CPU pad is 38mmx38mm, so you would easily get 4 pads for a 16mm PCB out of one CPU pad.
Not a steal, but at less than 1 euro per light it’s not a big part of a flashlight mod/build. I assume that you won’t add those
pads to stock flashlights.
I think i will try those pads some time…
Not bad these pads, 82W/m.K, thats better than most solder. But you have to apply constant pressure.
