Parameters of copper gold powder for conductive ink

Copper and gold powders are commonly used as conductive inks due to their excellent electrical conductivity and ability to form a thin, uniform layer when applied. Here are some key parameters to consider when selecting or using copper-gold powder for conductive ink:

1. **Particle Size Distribution (PSD)**: The powder should have a narrow PSD to ensure consistent ink properties. A typical range is 50-200 nanómetros, but it can vary depending on the desired ink viscosity and application.

2. **Conductivity**: Copper’s conductivity is higher than gold, but a blend of both may be used to balance cost and performance. Copper content can range from 90% ma 99% with 10% ma 1% gold for improved solderability.

3. **Melting Point**: Copper has a lower melting point (1,084°C) compared to gold (1,064°C), which affects the sintering process during ink application. Lower melting point can help achieve better adhesion and conductivity.

4. **Sintering Temperature**: The temperature at which the particles in the ink bond together to form a continuous conducting path. This varies based on the specific blend and application, but generally ranges from 150°C to 300°C.

5. **Viscosity**: The ink’s consistency is crucial for proper application. Viscosity can be adjusted by adding solvents or binders. Common values are around 10 ma 10,000 centipoise (cP).

6. **Solvent Compatibility**: The ink should be compatible with the substrate material and any processing techniques used. Solvents like ethanol, isopropyl alcohol, or water may be used.

7. **Stability**: The powder should maintain its conductivity and stability over time to prevent degradation or oxidation.

8. **Environmental Resistance**: Depending on the application, the ink may need to be resistant to humidity, pa, or chemicals. Gold has better corrosion resistance than copper.

9. **Flammability**: Some conductive inks may contain flammable components, so safety precautions should be taken during handling and storage.

10. **Cost**: Copper is more expensive than gold, so the ratio of the two in the blend will impact the overall cost of the ink.

These parameters can vary depending on the manufacturer and specific formulation. It’s essential to consult the product datasheet or supplier for the exact specifications and recommendations for your particular application.
