FH-98 matte tin plating additive
FH-98 Matte Tin Plating Additive: Technical Overview FH-98 is a high-performance additive designed for electroplating matte tin coatings, offering exceptional uniformity, solderability, and corrosion resistance. It is widely used in electronics, automotive, and industrial applications where a reliable, non-reflective tin finish is required. Key Features 1. Matte Finish: The additive produces a smooth, low-gloss tin deposit, ideal for applications requiring reduced light reflection or improved adhesion for subsequent processes like soldering or bonding. 2. Excellent Solderability: FH-98 ensures superior wetting properties, critical for PCB assemblies and electronic components, even after extended storage or thermal cycling. 3. Uniform Thickness: It enables consistent plating distribution across complex geometries, minimizing edge buildup and ensuring reliable performance in high-precision parts. 4. Low Stress & Ductility: The plated layer exhibits minimal internal stress, reducing the risk of cracking or whiskering, which is crucial for long-term reliability in harsh environments. 5. Wide Operating Window: Compatible with various current densities and bath temperatures, FH-98 maintains stability in both acidic and alkaline tin plating baths. Applications - Electronics: Connectors, terminals, and lead frames benefit from its solderability and oxidation resistance. - Automotive: Sensors and wiring components rely on its durability under thermal and mechanical stress. - Industrial: Fasteners and corrosion-prone parts use the coating for protection without reflective glare. Process Compatibility FH-98 works seamlessly with standard tin sulfate or tin methanesulfonate electrolytes. It is free of harmful brighteners, making it suitable for RoHS and REACH compliance. The additive also reduces hydrogen embrittlement risks, particularly in high-strength substrates. Advantages Over Alternatives Compared to glossy tin plating, FH-98’s matte finish avoids the need for post-plating treatments like brushing or masking. Its low organic content extends bath life and minimizes maintenance, lowering overall production costs. Conclusion FH-98 matte tin plating additive delivers a robust, cost-effective solution for industries demanding dependable tin coatings. Its balance of performance, ease of use, and environmental compliance makes it a preferred choice for functional and aesthetic applications alike.
