I worked with a customer about 2 years ago on a process similar using ProFlow head to put paste in holes for through hole... Similar to Pin in Paste. Somewhat successful; but ran into heat related damage issue from TH components through reflow.

Search "paste in hole" or "intrusive reflow"

Is there a way or process to use the screen printer to put solder paste in the thru holes ? The thing is that we are trying to put a thru hole in the same reflow oven with the other SMD components can some one explain how this work? thanks

most of thru-hole components can not handle the heat through the oven. they will be burn.

We do a lot of intrusive reflow. It works very well but the others are correct you need to verify that the part can survive the high temps. Most TH components are not rated for reflow, we have to test each one ourselves.

If you're using the Kapton tape to protect the gold fingers from solder splatter, my first instinct is to say,yes, you do need it. I've had the pleasure of paying to have gold fingers reworked in the past. It is not in-expensive; certainly not equa

Has anybody successfully used an automated dispensing system to put solder paste dots on .5 mm pitch pads?? I need to replace some Meritec tsop sockets and I don't want to use the single site stencils for .5 mm parts.

I am curious as to why you need to mix.... We use a 500g cartridge with air gun. Our process is remove the cartridge from the fridge, allow it to warm up to room temperature before inserting into air gun, then apply bead of paste to the stencil. N

How do people prepare there solder paste for screen print? We currently remove them from the fridge and mix them in a 500g solder paste tub mixer to mix the flux and paste together we waste to much paste at the moment as we only use the tub for 1

I won't say never but very rarely do we have problems with the flux seperating. The way we get around the 1-2 hour warmup time is this: The day before we run a particular job, the last person takes out the paste needed from the fridge as the last t
