Shandong Sino Steel Co., Ltd. is proud to present our premium Tinplate for Electronic Shielding, specifically engineered for demanding EMI/RFI protection applications. Manufactured in our ISO9000-certified facility spanning 10,000-30,000 square meters, this product combines 0.15mm-0.25mm thickness with continuous annealing (CA) to deliver exceptional formability and magnetic performance. Our tinplate is designed to meet the rigorous requirements of the electronics industry, offering high solderability and dimensional stability that simplify assembly processes. With an annual export value of US$2.5-5 million and a dedicated team of 101-200 employees, we ensure consistent quality and reliable supply chain across global markets.
Our tinplate is produced using advanced cold-rolling and continuous annealing technology, which provides a uniform microstructure and excellent magnetic properties essential for effective electronic shielding. The material’s high solderability is achieved through precise control of tin coating thickness and surface treatment, enabling strong, reliable joints without additional flux or surface preparation. This product complies with international standards for electronic components, making it suitable for applications in telecommunications, consumer electronics, automotive electronics, and industrial control systems.
Key Features & Technical Specifications
- Thickness Range: 0.15mm to 0.25mm – precise gauge control ensures consistent shielding performance and easy stamping or bending.
- Annealing Process: Continuous annealing (CA) – provides fine grain structure, improved magnetic permeability, and excellent ductility for complex forming.
- High Solderability: Optimized tin coating allows for rapid wetting and strong bond formation with lead-free and lead-based solders, reducing assembly defects.
- Standard Compliant: Meets relevant industry standards for electronic shielding applications, including RoHS and REACH (available upon request).
- Surface Finish: Available in bright or matte finish, with optional passivation or oiling to prevent oxidation during storage.
- Customizable Dimensions: Width can be customized from 600mm to 1250mm, with coil or sheet format options.
- Excellent Flatness: Low residual stress ensures minimal warpage during cutting and stamping, enhancing production yield.
- Environmental Compliance: Manufactured with sustainable processes, fully recyclable material.
| Parameter | Specification | Benefit |
|---|---|---|
| Thickness Tolerance | ±0.01mm | Ensures consistent shielding effectiveness and mechanical fit. |
| Tin Coating Weight | 2.8-5.6 g/m² per side | Balances corrosion resistance and solderability. |
| Magnetic Permeability (μ) | > 200 at 1 kHz | Excellent low-frequency shielding performance. |
| Tensile Strength | 270-350 MPa | Good structural integrity for stamped parts. |
| Elongation | ≥ 30% | High formability for complex geometries. |
| Surface Roughness | Ra ≤ 0.3 μm | Smooth surface improves solder wetting and appearance. |

Frequently Asked Questions (FAQ)
-
Q: What is the typical shelf life of this tinplate for electronic shielding?
A: Under proper storage conditions (dry, ambient temperature, away from corrosive gases), the tinplate retains its solderability and surface quality for at least 12 months. We recommend using within 6 months for optimal results. -
Q: Can you provide thinner gauges or tighter thickness tolerances than 0.15mm-0.25mm?
A: Yes, we offer custom thicknesses from 0.10mm to 0.30mm with tighter tolerances (e.g., ±0.005mm) upon request. Please discuss your specific requirements with our sales team. -
Q: Is this tinplate compatible with lead-free soldering processes (e.g., SAC305)?
A: Absolutely. Our high-solderability tinplate is designed to work with both lead-free and lead-based solders. The tin coating ensures excellent wetting even with higher melting point alloys. -
Q: Does the product have any certifications for environmental compliance?
A: Our tinplate is manufactured in compliance with RoHS and REACH directives. We can provide certificates of compliance upon request. Additionally, our factory is ISO9000 and ISO19011:2000 certified. -
Q: What are the standard coil dimensions for shipping?
A: Standard coil inner diameter is 508mm or 610mm, with outer diameter up to 1500mm. Coil weight typically ranges from 3 to 10 tons. Sheet format is also available with custom lengths. -
Q: How do you ensure consistent magnetic properties across different batches?
A: We perform rigorous inline and lab testing during production, including magnetic permeability measurement, thickness profile analysis, and solderability testing. Each batch is traceable and documented. -
Q: Can you provide samples for testing before bulk order?
A: Yes, free samples (A4 size or small coils) are available for qualified buyers. You only need to cover the shipping cost. Contact our team to arrange sample delivery. -
Q: What is the lead time for a typical order?
A: For standard specifications, lead time is 2-3 weeks after order confirmation. Custom orders may require 4-6 weeks. We maintain a buffer stock for urgent requirements.
