Copper sulfate plating additive for printed wiring boards (PWB) significantly improves via filling characteristics and uniformity of pattern plating thickness.
With the miniaturization and high performance of electronic devices, semiconductor devices are also becoming finer and more functional, and there is a growing demand for further miniaturization of wiring and reduction of via diameter in semiconductor package substrates that connect semiconductor devices to main substrates. Additionally, copper sulfate plating is required to have both high via filling capability and uniform plating thickness simultaneously. Okuno Pharmaceutical Industry has solved these challenges. Here’s what’s amazing! ◆ Copper sulfate plating additive for via filling: Topluchina GAP ◆ - Excellent uniformity of plating thickness in pattern plating - Reduces variation in plating thickness due to pattern density differences - Reduces variation in wiring width - Capable of filling large diameter blind via holes - Enables uniform electrowinning with excellent electric copper plating - Compatible with various via diameters - Excellent thermal shock resistance - Performs well across a wide current density (1.0 to 2.0 A/dm²) - Achieves high filling capability in baths with high sulfuric acid concentration - Allows for analysis of all additive components Our specialized sales representatives will propose the perfect chemicals and processes for you. Please feel free to consult us about anything.
