Thanks for the replys'. So are you saying that SMD adhesive contains a flux agent?, because at this point in the process the boards have no solder on them at all, it's all done at a solder bath after the chips have been bonded.

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.

I sent you some adhesive printing application data from MPM and Epibond for review. There's good stuff in docs. Run the ppt file as a Show to get the animation.

We currently use Epibond 7275 with MPM printers. Unfortunately we've had problems with Vantico (formerly Ciba) providing a consistent product. Last summer we had extreme difficulty printing due to excessively high adhesive viscosity (20% higher tha

I have a paper that was presented at the SMTA technical session at Nepcon West in Dec on screen printing adhesives. If you would like a copy send me an e-mail at brian.toleno@loctite.com and I can send you an electronic copy.

I've never printed adhesive but I assume that aspect ratio still plays a part with release. Maybe that .006" is just to thick to get good release. Can you step your stencil down from .006" to .004" or .005" for the 0402's?

0402 Adhesive printing is possible with thicker stencils in order to allow mixed component technology. We have successfully printed 0402's with a 0.008" thick SS foil. Total material release is not achievable at this thickness, but not required u

We have always had success with light cure adhesives for probe attachment. Try these guys for some samples. http://www.dymax.com

We use a product here made by Loctite. Its Loctite 383 thermal adhesive. It works fine. Steve

Hi all What adhesive you recommend to catch thermocouple to the board? (resistant to high temp and easy remove from PCB) Thank Frederic
