Abnormal performance and preventive measures of foreign white copper shielding cover in high or low temperature environments

As an important electronic component, the phosphor bronze shielding cover is widely used in various electronic devices to shield electromagnetic interference and ensure stable operation of the equipment. However, in practical applications, the phosphor bronze shielding cover may face challenges in high or low temperature environments, which may lead to abnormal performance. This article will be produced by Advanced Institute (Shenzhen) Technology Co., LtdYanbo brand white copper shielding coverAs an example, explore its performance changes and preventive measures under different temperature environments, and cite experimental data for evidence.

Basic characteristics of phosphor bronze shielding cover

Yangbai copper is a copper based alloy with nickel as the main additive element, named after its pure white color like silver. It has high strength, corrosion resistance, hardness, and good conductivity and thermal conductivity, and is therefore widely used in fields such as shipbuilding, petrochemicals, electrical appliances, and instruments. The Yanbo brand white copper shielding cover utilizes these excellent characteristics to provide effective protection for electronic devicesElectromagnetic shielding protection.

Performance Abnormalities and Preventive Measures in High Temperature Environments

Abnormal performance

In high temperature environments, phosphor bronze shielding covers may face the following performance abnormalities:

1. Discoloration and oxidation: High temperature can accelerate the oxidation reaction on the surface of white copper, forming an oxide layer that causes the color to turn yellow or even darker. Although this change usually does not affect the mechanical properties of the material, it can affect the aesthetic appearance.
2. Resistance change: High temperature may change the resistivity of phosphor bronze, affecting the shielding effect.
3. Material deformation: Extreme high temperatures may cause softening of the phosphor bronze material, leading to deformation and affecting the sealing and dimensional accuracy of the shielding cover.

experimental data

According to experimental dataYanbo brand white copper shielding coverAfter being heated in a constant temperature water bath at 70 ℃ for 30 minutes, its color began to slightly darken, and the change was more pronounced at 85 ℃. This indicates that the phosphor bronze shielding cover is indeed prone to oxidation and discoloration at high temperatures.

preventive measure

1. Choose the appropriate working temperature: Based on the specific application scenario, choose the appropriate welding furnace temperature to avoid oxidation and discoloration caused by excessive temperature.
2. Surface cleaning and protection: Keep the surface of the phosphor bronze shielding cover clean, remove impurities, and apply a protective layer if necessary to slow down the oxidation process.
3. Material selection: For extreme high temperature environments, it is possible to consider using phosphor bronze containing high-temperature resistant materials. Although the cost is higher, the performance is more stable.

Abnormal performance and preventive measures in low-temperature environments

Abnormal performance

Compared to high temperature environments, low temperatures have an impact onWestern white copper shielding coverThe impact is relatively small, but the following points still need to be noted:

1. Conductivity change: Although white copper has good conductivity, its resistivity may increase at extremely low temperatures, affecting the shielding effect.
2. Material embrittlement: In some cases, low temperatures may cause embrittlement of phosphor bronze materials, increasing the risk of fracture.

preventive measure

1. Temperature control: Ensure that the operating environment temperature of the phosphor bronze shielding cover is not lower than its minimum operating temperature limit.
2. Material toughness testing: Before use in extreme low temperature environments, conduct material toughness testing to ensure compliance with usage requirements.
