I understand that there may not be a lot of material on this, as most threads I've seen discourage doing it. It goes against DFM to do it. But I wish to use a large copper area instead of heat sink and thermal epoxy to cool a regulator. But I can'

Does anyone have any experience they are willing to share on Ag epoxy used as a copper through hole plating replacement? Was CEM3 used? What are the limitations? Thanks, Steve

Hi, The thing is I don't see, even if this was a viable process, how it would be better. It's still multiple layers of copper with components on one side of it. It's the same as what we do now, but just much more complex to build? Grant

First, don't get too excited about the thermal capabilities of conductive epoxy. An epoxy like DuPont CB-100 increases the amount of heat conducted through the barrel, but many over estimate what it can do. Calculations show for a 0.020" drilled

Look here: http://www.circuittechctr.com/ As a low cost approach, use copper foil purchased from a stained glass window hobbyist shop. Cut foil pieces to size with a sharp knife. Epoxy the pieces in place of the damaged pads. Tin and then solder th

| I am looking for a product to repair PCB mask (seal exposed copper) and fill Gouges in pcbs, any suggestions? Why not use an electonic grade 5 minute epoxy? As long as it's inert, I'd do it. Scott
