Wire glue - anybody had any success with it? For PCB vias?

post #1 of 3
Thread Starter 

I bought some of this stuff (or similar):-

 

http://www.ebay.co.uk/itm/Conductive-Wire-Glue-Paint-NO-Soldering-Iron-Gun-Solder-/320599571856?pt=UK_Home_Garden_PowerTools_SM&hash=item4aa5393d90#ht_1416wt_1398

 

It's carbon loaded glue, the stuff I bought claimed to have carbon nanotubes in it. I wanted it to make vias in PCBs.

 

I used to make a lot of doublesided PCBs at home. More recently I started buying manufactured ones because I was having to make the vias with wire soldered in from side to side, which is OK for some circuits, but it cuts down the packing density you can achieve and you have to bring connections onto leaded components from the solder side.

 

As I said, I bought the conductive glue to wipe into the vias in the hope that it would make a decent connection, but I got nowhere with it. Maybe my technique was at fault though.

 

I wondered if anybody had any success with it in any application?

I've been toying with the idea of getting one of the CNC paper cutters shown here

This will drill the holes for you, as well as mill the board. Then you could try the conventional method of thru-hole plating of drill first, squegee in conductive ink, electroplate the holes, etch or mill the board.

 

I have actually tried the silver-loaded paint, but maybe what I needed was a vacuum table like his, and a bit more persistence.
