You can run it on a carrier board to catch any paste that falls. When we do Pin in Paste, we sometimes over print the apertures a bit to get the extra paste volume.

I think over printing is the best option, and I like the idea of ordering a test stencil with increasing sized apertures. Make sure you go beyond what you think will work, just so you know where line is.

I have found that if you keep lead protrusion below the PCB at less than or equal to 0.030", you will not get icicling or "paste pukes"...

We are looking to underfill a small QFN and have never done this before. I have read the data sheet, but I have specific questions. Does anyone have experience using Loctite Eccobond 1216M?

I am using Bonotek 3400UF and Hysol for underfill application. What is your challenge on underfill process.

No pre heat the board and only apply at 2 sided of component. Yes, there is bleeding but as long did not covered nearby component is acceptable. We are using UV oven for curing.

Our application has a ground pad underneath. So I'm not sure if applying on two sides will work.

Even worse than that, $5K for registration to have the privilege of paying another $2K for a software switch to enable the existing hardware... It is a joy!!!

LOL! I don't think it will change until we (CMs) actually start pushing back on these companies. Nutek charged me $100 for a 100 page PDF of a conveyor last year..
