We're aware of no such standard. Check with ink suppliers [eg, Conductive Compounds, Coats Circuit Products, Creative Materials, etc] to confirm.

Dave, Do you know if such thermal transfer study with CB-100 (or equivalent) is available for review? My customer is pursuing this option and I am curious on how much improvement I would see by specifying a conductive via fill on the board. Rgds, P

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.

As you move, your clothing is rubbing against your body causing static to build up in the material. Since the material is a poor conductor, not all of the charge gets conducted through your skin to the heel straps. The smock is designed to prevent th

Dave, When we converted the Humiseal thermal conductivity info into W/m-*C we came up with .167 - .209. Did we do somthing wrong with our conversion?

We wouldn't expect the ceramic of the capacitor to conduct very much heat. [We're surprised how high the thermal conductivity of Al2O3 is: (30W/m-�C).] Can we assume that you're talking about parts that are defective at incoming inspection?

Hi All, Recently, I need to deal with a customer complaint that specify the PCBA white residue (flux residue from ecofree 303) may be the reason why the board intermittent. Anyone have such experience with this flux? Anyone can tell me is this flux

Hi, has anyone experienced discoloration of cured non-conductive epoxy? It turned from white to deep red. The parts were returned from customer and we noticed the color change and wondered what could cause epoxy discoloration.Thank you!

Even if it is no where near the pumps it is probably certified explosion proof. Could they have had aluminum sheets, painted them, cured them, stenciled conductive traces, cured it, stenciled conductive adhesive, populated parts, cured it then singu
