High-speed deposition for reel-to-reel plating
The new palladium nickel electrolyte PALLUNA® ACF-100 has all the technical advantages of other electrolytes - but without the smell of ammonia. The deposited layers are ductile, crack-free and resistant to abrasion. Furthermore, PALLUNA® ACF-100 has the cost benefit on its side: With comparable contact properties to those of hard gold, the palladium-nickel layer is by far the less expensive alternative.
PALLUNA® ACF-100 is a high-speed electrolyte, free of ammonia and chloride, for depositing a bright palladium-nickel-alloy in reel-to-reel lines (selective dipping, jet plating, brush plating) and in tabplaters.
Depending on the operation conditions, the electrolyte deposits alloy coatings with approx. 80 % of Pd. The alloy composition is largely independent of the current density. Electrolyte maintenance without ammonia and chloride. Breakdown products could be removed by carbon treatment easily. Continuous carbon treatment is feasible.
A brightener specially developed for PALLUNA® ACF-100 enables analytical electrolyte control. Thus, the increased requirements for new quality standards and stricter guidelines such as IATF 16949 can also be mapped by a compliant process control.
