copper pins to increase PCB heat sink capability?
T3sl4co1l:
I'm talking about what's manufacturable.
If you want to sit there skewering, soldering and cutting ten thousand wires a day to produce boards like that, be my guest! I'll stick to conventional means.

coppercone2:
thats a whole different story.
I think I have yet to make two of anything I built in my home. Mass production design is insanely neurotic shit I will not do without salary pay and benefits. 3/15000 PCB a year might go bad during soldering. Deploy ALL bosses :scared:
PPM's used to describe how many screws are put in wrong........... :-\
I try not to use this forum for corporate reasons
coppercone2:
don't forget to write a TPS with those PCBs

You can get vias plated shut (mostly in small sizes), you can also fill them with solder (harder to do with a paste reflow process, mind), both help significantly (~2x or better) with thru-conductivity of the board.
I suppose a lot of large (>40 mil?) vias, closely spaced, would be a moderately effective heatsink, but I'd rather use the drilling time to make a better thermal connection to a more massive heatsink, I think.

Are you referring to PowerPeg?
coppercone2:
thats extremely interesting. The only part that concerns me is the soldering process, that bit might cool the part quickly and cause unusual strain.
Is it something you should be worried about? I thought about mounting those parts upside down before and using indium nanofoil to solder them to heat sinks without much heat. His method is incredibly convenient.
