no, the oven is only used for curing adhesive and has never been used for reflow!!. I have always assumed that it has been the solvents in the glue that have evaporated off and then cooled again.

Hi Indy, Thanks very much for the info - very helpful. Was there any particular adhesive that stood out? Cheers, Rob.

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.

When I evaluated a new glue type, I simply used a shear force tester (Chatillon) to compare the cured strengths of the different glues. I sampled parts of different types; 0805, SOT23, 1206, and various tantalum caps. I analyzed the data based on e

No. My ovens are vented on a seperate system. Any other ideas.

Hi Dave, Thanks for the info, it will be helpful. Planning on trying it on a number of finishes, and have arranged for some samples of the adhesive - Loctite 3880 to start with. Have discovered something important already though - why not many peo

I am currently running several SMT lines that are placing components onto dispensed adhesive (Heraeus PD 944). My problem is that we have always had an issue with a resin type liquid �condensing� on the inside of our oven chimney and then running bac

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
