The Science Behind EMI Shielding
EMI shielding works through three primary mechanisms: reflection, absorption, and multiple reflection. The HANDA Quick-shield EMI Spiral Tube leverages all three to achieve superior performance.
リフレクション
The conductive stainless steel material reflects the electric component of electromagnetic waves. Materials with high electrical conductivity — such as stainless steel — are particularly effective for this mechanism.
吸収
The magnetic component of EMI is addressed through absorption, which is enhanced by the magnetic permeability of stainless steel. This dual-action approach ensures comprehensive protection across a broad frequency spectrum.
Multiple Reflection
The spiral geometry itself creates multiple reflecting boundaries that scatter electromagnetic waves, further reducing interference through internal reflections. This is where the Quick-shield design truly excels.
Technical Performance: Up to 165 dB Shielding Effectiveness
The most impressive feature of the HANDA Quick-shield EMI Spiral Tube is its shielding effectiveness — up to 1 GHzで165 dB. To put this in perspective:
| シールド効果（dB） | Attenuation Factor | Performance Level |
|---|---|---|
| 20 dB | 99% attenuation | Basic commercial |
| 60 dB | 99.9% attenuation | Good industrial |
| 100 dB | 99.99999% attenuation | Military/aerospace grade |
| 165 dB | 99.99999999999997% attenuation | Exceptional |
This level of shielding is essential for semiconductor equipment, where even minimal EMI can affect process parameters and measurement accuracy.
Seamless Continuous Forming: The Manufacturing Advantage
Unlike most domestic suppliers who rely on welding processes to create spiral tubes, HANDA employs seamless continuous forming technology. This manufacturing approach provides several critical advantages:
Consistent Dimensional Accuracy
The continuous forming process ensures that the entire length of the spiral tube maintains uniform outer diameter and consistent tolerance. There is minimal dimensional deviation between the ends and the middle section — a common problem with welded tubes that can lead to inconsistent contact and compromised shielding.
Structural Integrity Without Welds
Welded tubes inevitably have a joint that represents a potential weak point:
- Weld zones can create local variations in material properties
- Heat-affected areas may have different mechanical characteristics
- Weld seams can be points of failure under mechanical stress
HANDA’s seamless continuous forming eliminates these concerns, providing:
- Uniform material properties throughout the entire length
- No weld-related stress concentrations
- Complete structural integrity for long-term reliability
Customizable Lengths
The continuous forming process enables production of ultra-long lengths:
| Standard Length | Custom Options |
|---|---|
| 30 meters | Up to 100 meters or more |
| 60 meters | Custom lengths available |
This flexibility allows customers to order exactly what they need, reducing waste and simplifying installation.
