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

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.

We used to clean our stencils by hand as well but 2005 we steped up to a ppc-n29tp stencil ultrasonic cleaner has worked great for us I would suggest a machine cleaning system it gets the stencils more clean then doing it by hand

We are caught in a dilemma of PCB tab recycling....does anyone out there recycle their removed PCB tabs, or do you trash them?

We throw the break-off tabs in the scrap board bin. If your tabs have metal content, metals recycling firms will probably take them. Most tabs have no metal content.
