SPIRIT® T-420 high-speed matte tin plating technology is a kind of high-speed organic acid matte tin plating solution developed for lead-free plating layer, which can precipitate tin plating layer with required thickness on the base material in very short time. This technology is especially designed for high-speed flake type or taping type electroplating apparatus, which is applicable to weldability layer for semi-conductor lead frame and connector, etc.
Characteristics of the Products
1. It is the single dose product, which is easy to open the cylinder to replenish, and the component is not easy to lose balance.
2. The plating solution is stable and not easy to become oxidized.
3. The appearance after plating is even and meticulous, matte and soft, and the layer has good softness.
4. The plating speed is fast, and you can adjust the plating solution according to the situation to suit and be applied in low-, mediate- and high-speed manufacturing process.
5. The plated pieces are easy to weld, and capture the characteristics as good weldability and strong wetting force.
6. The plated layer has excellent whisker growing resistance ability.
7. The additive has no pungent smell, which is safe in nature and economic in application amount.
