Originally developed as low cost bonding wire as an alternative to gold wires, alloyed copper bonding wires have grown to be an advanced technical solution to many applications. They are very reliable, have advanced bondability and are suitable for fine structures.
Electronic devices need to perform more in a smaller space with every new generation. Due to this trend, components become smaller and smaller, structures finer and finer. At the same time, the cost pressure leads to the development of cost-effective solutions, such as copper, and the demand for higher reliability raises.
DKS copper bonding wires are in many cases a good alternative to expensive gold based solutions. With their ultra-fine diameters (0.6 mils or 15 µm) they are suitable for very small structures with ultra-fine pitch. By adding alloy elements to the bare Cu wire or using CuPd / AFPC core cu wire, our bonding wires show advanced reliability and very good bondability. In many applications copper wire bonding can even provide better performance and reliability than gold wire bonding.
Copper bonding wires are excellent for bonding in a ball / wedge process when using a reduced protective gas atmosphere. Processing is also possible in a wedge / wedge bonding process.
