We do have a commen problem with flux residues after the wave soldering process, even after using correct wave soldering profiles recommended by the flux supplier, The following flux type is being used Alpha EF 2210 VOC Fre Bellcore No Clean water Based.Can somebody give us some hints what could be the problem to have more flux residues on the PCBAs
1.Does this something to do with the solder mask DSR 2200 is commonly used on our PCBAs ?
2.Do you have any specific solder mask recommended for the following flux type we use ?
3.What could be the other parameters to play around to solve this problm, Whereas each and every PCBA has to be brushed after the wave soldering process?
