I have a unit in our shop that I don't know if it works or not. You can try it out if you like.

If you see flux separation mix the paste with a spatula before you transfer it. There is no need for a centrifugal mixer.

Lower humidity: Pros: Helps with mositure sentative devices. Cons: 1)Paste exposed to the dry air during your porcess will dry out quicker. 2) Drier air promotes more ESD issues, i.e. more electrostatic generation.

The problems that could be introduced by attempting to transfer paste into alternate containers far outweighs the penalty of wastage of paste.My grandmother doesnt receive a rebate from the filling stations because she only travels 50 miles a month w

I attached a RX picture. A lot of voids and micro balls arround the flux residue. What do you think, relow temperature reflow or OSP poor weeting.? I appreciate your comments. Thanks,

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

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.

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.

We used to use spray machines. We now have a PMR ultrasonic cleaner. Ultrasonic is the best in my opinion.
