Process Overview
Tin Plating
Tin plating provides a non-toxic, food-safe, and solderable coating with good corrosion resistance. It is widely used in the food processing industry, electronics manufacturing, and for decorative purposes. Tin's excellent solderability makes it the preferred finish for electrical connectors and component leads.
Coating Thickness
2–5 µm (electronics) | 5–15 µm (industrial)
Typical Turnaround
3–5 business days (standard)
Available Types
Types of Tin Plating
Bright Tin
A levelled, high-gloss tin deposit providing good corrosion resistance and excellent solderability. The most common tin finish for electronics and decorative applications.
Matte Tin
A dull tin finish that is whisker-resistant — important for fine-pitch electronics where tin whisker growth is a reliability concern. Preferred for lead-free electronics compliance.
Flow (Fused) Tin
Post-plated bright tin that is reflowed to create a dense, smooth, highly solderability and corrosion-resistant coating.
Why It Works
Key Advantages
- Non-toxic and food-safe (FDA compliant)
- Excellent solderability
- Good corrosion resistance in mild environments
- Low contact resistance for electrical applications
- Prevents galling on threaded components
- RoHS compliant (lead-free)
