You may need to specify what kind of information. For instance, Gold plating and Cad Plating are different process, such as Chemicals, anode materials /medials, rinse times etc, and even temperature, amperes are also differences/ and or results will be different. After plating, should there any Stress release if the plating processes have applied to metals? There are some well known MIL or AMS specification / guidances which may be we can share. Send me your contact & I will send some information to you as the files are big and copy right, and also I am not familiar how to attach the rar files here.
