Technic Post-treatment Chemistry

Product	Description
Tarniban CBG	Post-treatment process which effectively protects gold plated surfaces from corrosion and oxidation. Tarniban CBG forms a thin, colorless, transparent film on the plated surface which provides resistance to corrosion, especially during nitric acid vapor porosity testing. Tarniban CBG acts as a porosity “sealant” which enables lower gold thickness to be utilized. Tarniban CBG has no detrimental effect on the electrical properties of the substrate.
Tarniban E	Long life, effective anti-tarnish process for both silver and copper lead frame applications; no Cu peel-off; minimizes EBO.
Technic KS	Post-treatment process which effectively protects silver surfaces from oxidation/tarnishing. Tarniban KS forms a thin, colorless, transparent film on the silver which provides resistance to corrosion. The protective film has no detrimental effect on the electrical properties of the treated silver. Furthermore, Tarniban KS has no adverse effects on solderability or electrical properties. Tarniban KS was specifically designed to pass the most stringent Potassium Sulfide and Ammonium Sulfide corrosion tests.
Technic PST Neutralizer	Rinse aid which effectively neutralizes acid films from the plating process.
