Product Detailed
Related Categories:Electrical Wires
main joint material for semiconductor packaging

Copper bonding wire is a kind of material for inner lead with excellent electrical, thermal, mechanical properties and excellent chemical stability, mainly for ket materials of semiconductor packaging( molding compound, solder ball, high-density packaging substrate, conducting resin).

Product Advantage

   

1. Material costs:low

   

2. Conductivity: much thinner bonding wires during fine pitch packaging, excellent performance of fine pitch

                         (much smaller bonding pad), improving current capacity and property of power regulating        

                          device.

  

3. Thermal conductivity: 39.5KW/m2K

  

4. Mechanical properties: high mechanical property, larger tensile strength, better elongation, excellent ball 

                                         collar strength and higher arc stability.

  

5. Stability: stable-slow inter-metallic growth rate, improving mechanical stability and decreasing incremental 

                   resistance: moderate IMCgrowth enables bonding strength to be improved.

  

6. Solder joint: significantly reduced inter-metallic growth rate of solder joints. Resistance reduced, heat 

                         production decreased, bonding reliability devece performance improved. As the new products 

                         have their inter- metallic growth rate, resistance and heat production lower than gold wire, 

                         the amount of resistance increase with time and aging rate also is reduced.
