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?

We are looking into switching SMT adhesives, because of the lead time with our current supplier. So if you are using one that you would recommend, please let me know. We are dispensing with a glue machine ( Universal GDM ) Thanks in advance!

Check IPC-A-610C Chapter 12.1, Staking Adhesive

yes,it maybe lead to test failure,because solder joint is bad
