SP130 Tin Addition Agent
SP-130 organic grain refiner that is used to aid in the electroplating of tin in the application for SMOBC fabrication. SP-130 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. SP-130 eliminates the need for lead and fluoborates used in conventional etch resist plating processes If an extra wetting agent is needed, use SP130W. Please consult your service representative for additions.
