Bright Tin-Lead Process

STANNOSTAR HMB is a fluoborate-free, low foaming tin-lead plating process. Formaldehyde-free, it is specially formulated for rack and barrel plating to produce bright tin-lead deposits.

STANNOSTAR HMB solutions include 60/40, 90/10 and 98/2 tin-lead alloys. The solutions can be operated over a wide range of operating parameters including current density and agitation, while maintaining constant depositproperties. When neutralizing the rinse water, the tin and lead salts will precipitate completely – an important improvement over fluoborate systems. STANNOSTAR HMB produces consistently uniform and bright solder alloy compositions that eliminate uneven, “blotchy” areas.
