Thank you. I do feel that the document is very lacking in detail. It mostly says "yes, it needs cleaned. Make sure the cleaning process doesn't screw it up". The majority of boards that get wiped are already populated on the other side. So that lim

Look at IPC-7526 - Stencil and Misprinted Board Cleaning Handbook, Misprinted Circuit Board CleaningCLEANING [ https://www.multi-circuit-boards.eu/fileadmin/user_upload/downloads/leiterplatten_design-hilfe/ipc-7526.pdf ] ITW/EAE says "Typically, th

When we get a bad print at SMT, the operator uses the alcohol wipes and wipes the paste off the board. Then they use compressed air and another wipe. In most cases this is sufficient. Most vias are tented, but there still remains some solder sphere

Water will not remove no clean flux residues because they are not water soluble. Solder paste with no clean flux should only be used when the assemblies do not need to be cleaned. That said, you can buy special cleaning solvents specifically for re

I am a PCB Designer and I have to put a note on the assembly drawing to tell the assembler how to clean the board. This is new to me. Here is a sample note. Can someone give me some feedback on it? "Use water washable, no clean solder paste for t

I was using a combination of Alcohol and then compressed air for a while because I didn't wanted to add new hazardous chemicals into my factory but after looking into Vigon SC200 with a H/F/R of 0 I decided to try it. Since I started to use it, my

Try a fid teach on your changers. I don't recall how to do it but you'll find it pretty easy if you surf around. Also, the seals on the nozzles must be good and soft. If you can still get them new, I'd replace. Same goes for seals in changers. C

I get a Timeout waiting for nozzle changer vacuum buildup failure every time I go to run my 1998 GSMx machine. The problems seems to be that once in a while (it seems to be random) the spindle does not line up exactly in the center of the nozzle cha

Does anyone have a recommendation for a cleaning solution used in an ultrasonic cleaner for cleaning RMA solder paste off stencils and adhesive off pcb boards. I am going to be evaluating Armakleen 2001, Zestron Vigon SC 200, and Aqueous Technologies
