Hi, Does anyone have any experience of using electrically conductive adhesives, including info on the following? 1) Autodispensing/screen printing 2) Curing temps/profiles 3) Quality/conductivity of joint 4) Product recommendations Our customer w

We have done some work with conductive adhesives. The main lesson is: They do not adhere well to solder. * For components, a silver-palladium or gold end termination is recommended. * For substrates, gold over nickel should work well.

Hi Rob, I had tried printig anisotropic conductive adhesive as a replacement for solder paste. Following were my finding. Adv: - curing temp is around 120-150C as compared to 217C (Pb-free) solder. - good electrical conductivity, since it is usual

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

Thanks Dave, From what I remember a lot of components went away from Silver Palladium to "base metal" terminations because of the difficulties in continuation of supply & stability of price. (Something about being mined in Chechnia or the Congo?) W
