Lately, many companies have hopped onto the Copper Wire Bonding bandwagon due to the rising gold price and the need to lower manufacturing cost. Copper wire offers significant cost advantage over Gold wire. It is also an excellent replacement for Gold wire due to its similar electrical properties. Self inductance and self capacitance are nearly the same for Gold and Copper wire and Copper wire has lower resistivity. In applications where resistance due to bond wire can negatively impact circuit performance, using Copper wire can offer improvement.
This sudden surge of embracement of the Copper wire as substitute for Gold wire has resulted in a big rush for Copper wire manufacturing equipments like the K&S ProCu Wire Bonders which is the fastest, with largest bondable area and build from the proven IConn platform.
