PCB Cleaning

Group Administrators: 1 | Group Member: 22 | Group Threads: 18

When cleaning assemblies (PCB cleaning, PCBA cleaning), the primary goal is to remove resin and flux residues from populated boards and hybrids as well as production related residues created by handling. It is recommended not to clean Circuit Boards (PCB) manually with a cleaning brush as this can damage the components.

We have a customer whom we have built boards for. They want a "cleaner no clean look".
The process uses a no clean Kester 256 SN63 solder paste. After reflow the "residue" noted by the client is too much. We have tried a few things. We are a small shop with a closed acqueous cleaner. We have gone over the myriad of reasons why the customer is asking for something the materials were not designed to deliver. The customer is always right so.....
What do we do given that we do not have a cleaner that can take a saponifier? We could hand clea or we have a small sonic bath..
