Often, your solder paste supplier provides guideline on handling their solder paste. For instance: http://www.aimsolder.com/techarticles/tech%20sheet%20paste%20handling.pdf We have no relationship, nor receive benefit from the company referenced ab

I have been working on the SMT area for a while now, must of my experience is on programming and pick and place, now in my new job I have to control a complete SMT line and I have a little knowledge on working with solder paste but I like to read mor

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

Search "paste in hole" or "intrusive reflow"

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

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.

I have concern about cleaning solder ball after misprinting paste on PCB, currently use vigon 200 with ultrasonic generate but only 70% solder ball able to remove, Any other method or equipment can help to clean solder ball.

In piggy back on Chunks' comments, what you might wipe it with can be the problem. Alcohol absorbed by the solder paste inhibits the effectiveness of some cleaning chemistries, and driving it into the nooks and crannies exacerbates the problem. If

Hi, I am new on this, I want to ask you what is HASL finish, OSP, FPY, ppm. About to eliminate the Nitrogen in reflow soldering, a listen about one solder paste that no requires Nitrogen, the solder paste is called Indium, I don't know if this is tru
