How The Tin Plating Process Works
Tin plating electrodepositing is the process of depositing a thin layer of tin onto a metal substrate using electrical current in a chemical bath. The result is a uniform, adherent coating that enhances the base metal’s functional properties.
The process consists of four steps:
- Step 1: Surface preparation involves thoroughly cleaning the substrate to remove oil, grease, and other contaminants that would compromise coating adhesion. Methods can include alkaline cleaning, grit blasting, or solvent-based degreasing, depending on the substrate material and condition.
- Step 2: Activation is the process of rendering the substrate surface chemically reactive so that the tin coating will bond properly to it. The cleaned substrate is treated with an acid solution to remove any remaining oxides and etch the surface in preparation for electrodeposition.
- Step 3: Electrodeposition immerses the substrate in a plating bath containing an acid or alkaline tin solution, where it acts as the cathode in an electrical circuit. As current flows, positively charged tin ions in the solution are deposited onto the substrate’s surface at a controlled rate to achieve the specified coating thickness.
- Step 4: Post-treatment includes rinsing and inspection to verify coating thickness, adhesion, and overall quality. Depending on the application, passivation may be applied for additional corrosion protection, or heat treatment may be performed to prevent hydrogen embrittlement.

Tin Plating for EMI/RFI Honeycomb Shieldings
Honeycomb shielding is a ventilation panel used in electronic enclosures that need to block electromagnetic and radio-frequency interference while still allowing airflow. These panels are found in military shelters, electronic cabinets, telecom base stations, and other environments where sensitive equipment must be protected from EMI/RFI. The honeycomb structure provides a high percentage of open area for air circulation while using waveguide design principles to attenuate interference.
Tin plating is one of the most effective coatings for honeycomb shieldings because its conductivity maintains the low-impedance contact required for shielding performance. The corrosion resistance of the tin deposit also ensures long-term reliability in demanding environments where panel degradation would compromise attenuation levels. PFI has extensive experience in plating honeycomb shieldings to meet the strict requirements of military and industrial applications.
Mil-T-10727 Tin Plating
We plate to Mil-T-10727 and provide certification of compliance for military and defense applications. This military specification defines the requirements for electrodeposited tin coatings on ferrous and nonferrous metals across multiple thickness classes designed for different service conditions. Mil-T-10727 is required for Department of Defense contracts and has been widely adopted across the aerospace and electronics industries.
ASTM-B545 Tin Plating
PFI also plates to ASTM B545 specifications for commercial and industrial tin plating applications. ASTM B545 is the industry standard for electrodeposited tin coatings and defines requirements for thickness, adhesion, and corrosion resistance. We apply this specification to a range of components, including bus bars for electronics and other parts that require tin plating for solderability or corrosion protection.
