Mike, I do not believe the PumpPrint stencils are use for applying paste. We used them for applying adhesive on a particular PCB that required tall dots for larger components. We use the ProFlow system exclusively for paste and adhesive application

Xrays go through aluminum quite well. I've xrayed BGAs with heat sinks that were well over an inch tall and they only made faint shadows. What material is the bottom of the PCB? And how are you going to bond to it?

Using the 72A FNC nozzles to place 3216 resistors, and 74F nozzles to place PLCC6 LED's. The LED's ar 5mm x 6.5mm x 2.4mm tall.

Yes, thank you. Found out that machine ran over two parts to tall and damaged the cover plate over the centering.

What are the chances for redesign the board or use substitute for the current tall part? Sometimes the hassle you want to go through could be avoided. How about change the box the device goes to or modify/ customize it to fit this part better in?

That is why we don't care if it is Top or Bottom. We call them first (process) side and second (process) side. Often you will have tall and heavy parts on both sides, so you will have to glue them.

Now, if before reflow everything looks fine, something happens in the oven. As it is second side, I would ask if there are parts close to edges or very tall parts on the first side that might be getting in contact with something in the oven? In my o

Do you remember how tall if a component works on the sapphire? Basically it is a comet III, right? How did they speed the old comet up?

Thank you, I am researching our options, and that is a good alternative.

There may be other ways around it - there is some excellent 3rd party support for the old GEM series especially in Europe and the UK, but I'm guessing you are in the USA?
