led packaging gold wire and copper wire packaging difference
led packaging gold wire and copper wire packaging difference
LED copper wire and gold wire have advantages and disadvantages:
- copper wire : has the advantages of high cost performance, good electrical conductivity and thermal conductivity, is suitable for cost-sensitive projects. , however, copper wire is easy to oxidize, process stability is relatively poor, and may not meet the performance requirements under high requirements.
- gold wire : has the advantages of large electrical conductivity, corrosion resistance, toughness, excellent chemical stability, can ensure the stable work and service life of LED lamp beads. but gold wire is expensive, increases the cost of packaging. In addition, the choice of gold wire diameter has an important impact on the life of LED light source, diameter is too small may lead to increased resistance, fusing current reduction, thereby reducing the life of the light source.
difference:
1 electrical conductivity : gold wire conducts electricity better than copper wire, because of the lower resistivity of gold, is better in terms of current conduction and voltage drop.
2. Thermal conductivity : copper wire has better thermal conductivity than gold wire, copper has higher thermal conductivity, helps to dissipate heat faster.
3. Cost : The cost of gold wire is much higher than that of copper wire, , therefore, copper wire has more advantages in cost control.
4. Oxidation resistance : gold wire has strong oxidation resistance, is not easy to be oxidized, and copper wire is easy to be oxidized, need to be protected.
5. Process stability : gold wire process is relatively mature and stable, while copper wire process may face problems such as solder joint defect and oxidation in practical application, affects the reliability and yield of products.

Compared with copper wire package, generally has a longer service life;Here's a comparison:
Gold wire package advantage :
- Gold wire has high electrical conductivity and corrosion resistance, excellent chemical stability, can ensure the stable work of LED lamp beads.
- Gold wire package can effectively reduce the risk of resistance and fusing current extend the life of LED light source.
Copper cable packaging problems :
- Copper wire is easy to oxidize, may lead to gold ball deformation, affect the product pass rate.
- Copper cables are not easily combined with supports, may cause poor welding, reliability risks.
- Copper wire packaging has higher requirements for production control, may increase the defect rate and cost.
To sum up, gold wire package usually has a longer service life than copper wire package because of its superior performance and stability.
How to distinguish LED gold wire or alloy wire?
- Color: Gold wire is golden yellow, alloy wire color may be different, such as palladium gold alloy wire is silver.
- Detection method: Through material analysis instruments, such as energy scattering X-ray analyzer (EDS), gold and alloy lines can be accurately distinguished.
