Brighteners /carriers concentration can be analyzed by qualiplate CVS (cyclic voltametric stripping). However for gold plating baths this does not apply. Usually brighteners in gold plating baths are not being analyzed, they were just be added in direct proportions with gold content in a bath. So if you know the gold content, you have the idea how much brightener you will add.] Hope this helps Jonathan Fairchild semiconductor Package Technology Group Jack Petyak <[log in to unmask]> on 03/29/2000 08:57:03 AM Please respond to "\"TechNet E-Mail Forum.\" <[log in to unmask]>, Jack Petyak" <[log in to unmask]> To: [log in to unmask] cc: (bcc: Jonathan A Noquil/Cebu/Fairchild) Subject: [TN] Plating processes Anyone have any input about how to analyze carriers and brighteners in plating baths? What about potential problems with gold plating? I'll probably have more plating process questions as I get deeper into my project so if the experts can offer any advice I'd appreciate any help.
