Research on Weather Resistance Testing Technology of Gold Plated Copper Foil Tape

Gold plated copper foil tape, as a high-performance electronic material, is widely used in electronic packaging, electromagnetic shielding, and communication fields due to its excellent conductivity, corrosion resistance, and good adhesion performance. However, in practical applications, adhesive tape needs to withstand various environmental conditions such as temperature fluctuations, humidity changes, and ultraviolet radiation. Therefore, it is crucial to conduct weather resistance testing on gold-plated copper foil tape to evaluate its stability in long-term applications. This article will provide a detailed introduction to Advanced Institute (Shenzhen) Technology Co., LtdResearch Platinum Brand Gold Plated Copper Foil TapeWeather resistance testing technology and sharing relevant testing data.

Test purpose and method

Purpose

The weather resistance test aims to evaluate the performance changes of gold-plated copper foil tape under different environmental conditions, including its conductivity, adhesion, and stability of physical properties. By simulating extreme environmental conditions, test the weather resistance of the tape during long-term use to ensure its reliability in various application scenarios.

test method

1. High temperature high humidity test: willResearch Platinum Brand Gold Plated Copper Foil TapePlace it in an environment with a temperature of 85 ℃ and a humidity of 85% RH for 720 hours to evaluate its stability under high temperature and high humidity conditions.

2. Low temperature test: Place the tape in an environment of -40 ℃ for 240 hours to evaluate its adhesion and physical properties under low temperature conditions.

3. UV aging test: Using UV lamps to accelerate the aging process, simulate long-term sunlight exposure, and place the tape under UV radiation for 720 hours to evaluate its anti UV aging performance.

4. Performance testing: After each testing cycle, conduct conductivity, adhesion, and physical performance tests on the tape, including resistivity, peel strength, and elongation.

Test data and result analysis

High temperature high humidity test:

• Initial resistivity: 0.001 Ω· cm
• After 720 hours, the resistivity is 0.0012 Ω· cm, and the resistivity change rate is less than 2%, indicating that the conductivity of the tape is stable under high temperature and high humidity conditions.
• Peel strength: The initial peel strength is 2.5N/cm, and after 720 hours, the peel strength is 2.4N/cm. The change rate of peel strength is less than 4%, indicating that the adhesive performance of the tape is stable under high temperature and high humidity conditions.

Low temperature test:

• Initial elongation: 10%
• -After 240 hours at 40 ℃, the elongation rate is 9.5%, and the rate of elongation change is less than 5%, indicating that the physical properties of the tape are stable under low temperature conditions.
• Peel strength: The initial peel strength is 2.5N/cm, and after 240 hours at -40 ℃, the peel strength is 2.45N/cm. The change rate of peel strength is less than 2%, indicating that the adhesive performance of the tape is stable under low temperature conditions.

UV aging test:

• Initial resistivity: 0.001 Ω· cm
• After 720 hours of UV aging, the resistivity is 0.0013 Ω· cm, and the resistivity change rate is less than 3%, indicating that the conductivity of the tape is stable under UV aging conditions.
• Peel strength: The initial peel strength is 2.5N/cm, and after 720 hours of UV aging, the peel strength is 2.35N/cm. The change rate of peel strength is less than 6%, indicating that the adhesive performance of the tape slightly decreases under UV aging conditions, but still remains within an acceptable range.
