Removal of copper ions on MSA based
plating solution [Philippines]
+++
Is there a way or method to remove or reduce coppers ions on SnPb
or pure Sn plating baths (MSA based)? Except plating it out at high
current density.

Kumusta na kayoo, Forget it Paray, dump the bath and start over
before the solder starts voiding during solderability test after
steam age. With SnPbMSA baths its good to use two baths, one for
striking and one for plating since the strike will get loaded up with
Cu if you are not Ni plating prior. Then just routinely dump the
cheap strike.
