who can tell me how viscosity measurements are really effective in smt process control? what can I monitor? Is it depending from fine pitch size? Thanks a lot. g. d'andrea

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

SMT adhesive is hydroscopic. Some types absorb moisture faster than others. Moisture+SMT adhesive= pourous adhesive after cure. Excessive cure ramp rates can also contribute to porosity.

They still make SMT adhesive?!?!?! Holy SMOKES BATMAN. I haven't used SMT adhesive in, oh 9 years. But, back in "The Day", I found loctite to be best. Call your local rep in, show them your process and make them earn their money.

Loctite 3609 is a pretty good smt adhesive. I'd actually recommend the Loctite 3621 instead though. It's a better adhesive on some of those pain parts plus it's actually less expensive than the 3609

All of the SMT adhesives that I have used are non-conductive by themselves. I assume that the solder joints are formed by wave soldering?
