You'll be able to tell pretty soon if this will work. * Our bet is the epoxy will corrode the silver. * Another concern is that you're not fusing the silver to the copper. Why not ask the imm silver suppliers: * Alpha Level Silver [ http://www.al

Rob: Why aren't the board houses over there going to lead-free HASL [not that HASL is the most wonderful thing on the planet]? What's the price delta on an unit basis for a x-HASL, now imm Ag board? Anyhow back to the point, so, you're proposing t

Sand is not a great conductor, compared to copper. Never heard of using the stuff on RF boards. Our board fabricator uses Dupont CP100, now CP101, [or something like that cuse who's going to check?] when plugging via on cheap boards. Your board fa

I am looking to apply 10-15�m of a conductive material that will withstand 280�C. Our product consists of an alumina substrate sputtered with NiCr (2000�) and Copper (2000�) and 15-60 �m of electroplated copper (all metals patterned on the substrae)

Hi, Did anyone experience a problem with electrically conductive silver filled epoxy is resistive due to galvanic reaction? I'm having this problem when attaching components to Ni plated housing while conducting an experiment to cost reduction for Au

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 information or experience with the use of conductive epoxy in leu of solder. I have a unique application that might lend itself to this technology. I am looking for manufacturers, printing, curing and reliability info. | |

Hi Etimov, Understood that to us assembling parts that IPC is king, however it isn't neccesarily the bible for design engineers. We've had customers demand almost zero voiding, or had to use conductive epoxy to avoid it. For some of us solder joi

Dave, I use Dexter Hysol epoxy 9340 gray. It's a two part epoxy kit. Thermally conductive and electrically insulative. Cures in about 10 minutes at 100C. Terry
