TinPlate PC-625 is an organic grain refiner that is used to aid in the electroplating of tin in
the application for SMOBC fabrication. TinPlate PC-625 is formulated to improve the
throwing power of the bath, aid in refining grain structure, and prevent treeing. It is added
based on amp hours and will increase limiting current density and control deposit
characteristics over a wide range of current densities. It produces a bright silver white
deposit. TinPlate PC-625 eliminates the need for lead and fluoborates used in
conventional etch resist plating processes. If an extra wetting agent is needed,
use TinPlate PC-625 Starter. Please consult your service representative for additions.
