We love Loctite 3609 as a chip bonder, but would never consider it to secure large components

We use Loctite 3609 - it's good stuff.

We currently use Epibond 7275 and it cures way too quickly to allow the component to settle down on the board. Have you used the Loctite 3609 in the application i'm speaking of with success?

We view both Epibond 7275 and Loctite 3609 to be very similar. They're competing chip bonders.

Doesn't sound like we use it exactly like your application. Similar to what davef says we use it for smaller to medium size or dense parts (sigle dot under the center of the part) that have potential to fall off on 2nd side processing. I can say it

After doing some more research it looks like Loctite made a material called Cornerbond 3515 that seems as if it has the characteristics we are looking for such as curing after the solder is liquidous. But it appears that it isn't manufactured anymore

In BIG-boy, high vibration applications to secure large components, we've used 3M #2214 structural adhesive [One part, 250*F (121*C) curing 100% solids, paste consistency epoxy adhesives designed for bonding metals and many high temperature plastics

I am attempting to identify a good epoxy to hold on larger parts on thru the reflow process for the opposite side. We currently dispense epoxy prior to second reflow on the corners of the component because the epoxy we use cures before reflow and doe

We've used our standard chipbonder- Heraeus PD944- for this type of application. While it does cure before reflow, when the part is placed onto the site, the material compresses and spreads and thus that potential standoff isn't an issue. We've als

I have some large ROHS SMT inductors that are moving during the reflow process. I have tried adding extra solder, gluing and doing both. I don't know what else to try, any suggestions?
