• copper might seem to be a natural fit for chip to-package wiring because of its favorable cost, high electrical conductivity and other characteristics,in fact it presents a number of manufacturing challenges which hindered adoption. But over the
  past decade, TI and other companies have dedicated development efforts and considerable quality and reliability testing in order to overcome these challenges. Today, copper wire bonding has come into its own as a proven solution for packaging, so much
  so that it has become standard for TI products.

Typical chemical analysis:

Trace elemental analysis of ultra high purity 5N or 6N copper is challenging due to both the complete elemental coverage required in the assay and the ultra low target levels.
For example, the sum of all impurities in a 6N Cu (99.9999% purity) is only 1 ppm. For such ultra high purity Cu materials, a routine, full mass scan quantification of all elements at single digit ng.g-1 levels is required.
In this application brief the Thermo Scientific™ ELEMENT™ GD high resolution glow discharge sector-field mass spectrometer is assessed for the impurity analysis of high purity copper.

Our 6N ultra high pure copper use electrolytic way:

• First, our workers cut,cleanout the 99.95% pure copper material ,and then put them into the equipment  which can purify 99.99995% pure copper from 99.995% pure copper material. In the purification process,our professional workers can control the electricity,the rate of circulation and temperature.And they also can put additive into the electrolytic.
• In short ,We mainly adopt electrolytic refining method which is used to obtain high purity copper.The pocess is highly purified of electrolyte with a higher purity of copper electrolysis again.
• Depending on the type of electrolyte, the system can be divided into three kinds. First, the copper sulfate solution;Second,copper nitrate solution;Third,copper sulfate solution and copper nitrate solution
