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 am a lay person researching the application of non-woven material in stencil rolls either using branded material or non-branded alternatives for DEK, MPM Panasonic machines in SMT environments. I have read a number of articles referring to aqueous

Has anyone built using the ALIVH PCB (0402, 0.8mm pitch uBGA) on the SMT line? I would like to know any process issues (paste printing, p&p, reflow) related to processing this pcb. Specifically, what type of solder paste was used (no clean) and wha

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

We are going to be using a no-clean paste (smt)and no clean wave solder flux on a small pcb we will be doing here soon. As far as the wave process, should i purchase a new fluxer stone for the no-clean. Should I also purchse the recommended thinner o

We have been having problems with solder paste balls around fine pitch ICs and have decided that cleaning the boards in an ultra sonic cleaner may reomove these solder balls. However we are worried that the ultrasonic cleaning process may damage the
