Immersion Gold Processes Uyemura
Uyemura TWX-40 Immersion Gold creates deposits of 4-8 μin gold in a single step. Processes are also available for direct immersion gold (DIG). All immersion gold minimizes nickel corrosion produces high reliable solder joints and optimizes gold distribution.
Chat OnlineSignificant contribution of three-phase boundary for the
The reason for the current enhancement was confirmed to be due to the ORR at the three-phase O 2 gas/electrode/solution boundary based on the effects of the concentrations of O 2 in the gas phase and in solution as well as the immersion depth of a gold wire electrode on ORR behavior.

A gold nanorod (AuNR) array electrode was employed to record SERS spectra as a function of immersion time in electrolyte solutions of tetrathionate trithionate the Au(S 2 O 3 ) 2 3- complex sulfide and thiosulfate. The generalized two-dimensional correlation spectroscopy was employed to deconvolute broad bands in the SERS spectra.
