Hi Loco, my PCBA got top side and bottom side and 90% SMT and 10% THP (top side) which need to be cover by wave solder. And that's why i need to go through reflow and wave.

Even a slight amount of epoxy will prevent a part from soldering. Look at the part after print. If you any trace of you epoxy between the pad and part, you have a potential problem.

I'm still confused. Why reflow solder a part when you're going to wave solder it? Seems like a waste of resources and material.

So, you're curing glue on a thermal recipe intended for reflow even though your supplier recommends that you cure at 150C, because you want to use paste that isn't necessary.

Nope, my thought process ejected from my brain and will have to watch this thread pan out from the side lines. Should be interesting.

It's OK, really. Stephen is carrying the torch for you now, although I don't know if dave is in or out at this juncture.

Shouldn't someone LIGHT the torch first? Good ol' Adolph starting a tradition that carries into today.

Shy You should try SMT-5. First solder PTH comps, then apply paste with your pick and place and apply glue with ur screen printer and come back to place smd with pick and place and then reflow. You will get great results. Good luck

Hi Habsfan, if we're mount the THP first, we can't run SMT due to tTHP is tall and big which will causing the PNP to be chaos. Btw, my solder paste location is more than glue location which (solder paste : glue) is 2:1.
