Hello everyone, Could you help me out with the following request? I would like to know what kind of protective coating PCB manufacturers are using to cover the bare copper at the final stage of the manufacturing. I know about Entek. Are there others? What is the thickness applied? Would bare board test will be carried out before or after that coating? Where can I find information about the composition of the materials David Banitt President Exsight Ltd 12 Hamada st.
