ARGUNA 630 alkaline hard silver electrolyte has excellent electrical properties

ARGUNA 630 alkaline hard silver electrolyte has excellent electrical properties, is ideal for electromechanical components exposed to high mechanical stress. Additives significantly increase wear resistance compared to conventional silver layers, achieving a stable hardness of 120 to 130 HV, even after thermal aging. More

NIPHOS 968 electrolytic nickel produces a bright, RoHS finish with corrosion properties equal to electroless nickel, accommodates up to 13% phosphorus for high hardenability. More

Hard Silver replaces gold Hard Silver replaces gold

MIRALLOY, industry’s best alternative to silver, palladium and nickel. Deposits up to 8μm with high uniformity and high abrasion/corrosion resistance. More

From Uyemura Labs:


KHW-NC semi-bright alkaline copper plates directly onto aluminum

KHW-NC semi-bright alkaline copper plates directly onto aluminum, eliminates double zincating. Bond strength is sufficient to pass the standard Heat-Quench Test, ASTM B571. Small grain deposits are dense, corrosion-resistant, and resist thermal shock. More

TWX-40 reduction-assisted immersion gold bath

TWX-40 reduction-assisted immersion gold bath meets demand for thicker gold in ENIG, ENEPIG, EPIG. Single step process deposits up to 8 μin without compromise of the underlying nickel, substantially widens the operating window for wire bonding. More

BlackNight Ultra-black finish

BlackNight is Industry’s Blackest
Ultra-black finish combines high density topography with exceptional hardness. An entirely new film “shape” with extraordinary micro-uniformity and corrosion resistance. More
