How to Solder Shielding Tubes
Conclusion: Copper foil and tin-plated types can be soldered directly to the tube surface.
Shielding tubes are used to suppress noise in cables, and to maximize their effectiveness, it is important to connect and ground the earth wire. Below are three methods for soldering shielding tubes.
3 Types of Shielding Tube Soldering Methods
METHOD1
Soldering to Flat Braided Wire
Limited soldering pointsWith general aluminum shielding tubes, soldering cannot be performed on the aluminum foil part. Therefore, soldering is performed on the braided, plated copper wire part that is woven into the tube.
Since the soldering points are limited, the degree of freedom for grounding is reduced.
METHOD2
Soldering using a Stainless Steel Band
Large contact area, increased workThe shielding tube is folded back outwards like peeling a banana, and a stainless steel band is wrapped around that part. Soldering is then performed on the wrapped stainless steel band.
While a larger grounding area can be expected to improve effectiveness, work efficiency decreases due to the increased number of steps.
RECOMMEND3
Direct Soldering to the Tube Surface
Anywhere / Excellent work efficiencyIf the shielding tube is made of copper foil, stainless steel, or tin-plated material, it can be soldered directly to the tube surface. All of our copper foil shielding tubes, copper braided tubes, and stainless steel braided tubes can have earth wires soldered directly to their surfaces.
For braided tubes: Since they are mesh-like, it is easier to solder if you stretch the tube to eliminate gaps when soldering.
For copper foil shielding tubes: Soldering can be performed anywhere on the copper foil part. Typically, the earth wire is soldered to the end of the tube to shorten the grounding distance.
Comparison of the 3 Methods
| Method | Solderable Points | Work Efficiency | Grounding Performance |
|---|---|---|---|
| ① Soldering to flat braided wire | △ Limited | ○ Relatively Easy | △ Partial |
| ② Using stainless steel band | ○ Around the entire fold-back | × Increased work steps | ○ Large grounding area |
| ③ Direct surface soldering (Copper foil/tin-plated type) |
◎ Any desired point | ◎ Most efficient | ○ Stable grounding |
Summary
Method 1: Flat braided wire
Aluminum foil types can only be soldered to the flat braided wire. Soldering points are limited.
Method 2: Band fold-back
Soldering to a stainless steel band wrapped around the folded-back part. Large grounding area.
Method 3: Direct surface (Recommended)
Copper foil/tin-plated types can be soldered anywhere on the tube surface. Excellent work efficiency.
