I want to know full tin coating by hot-dip process to copper wires. It should be bright tin coating. What to do for getting brightness of tin coating on copper wire. Please describe preparation of bath, pre cleaning and post cleaning. Your reply is awaited.

Thanking you regards,

You probably need to bright dip the wire, and clean and flux it before tin dipping. I imagine you will need to reflow the tin after dipping.

Mr. Venkatesha, we thank you for visiting finishing.com, and we don't want to give you a hard time. But you have asked a whole series of very broad general questions that constitute enough subject matter to fill entire textbooks. No one will write a book for you in reply.

Please see if the tin associations have any booklets available that will help you get started. Visit a hot dip tinning shop. Talk to the equipment suppliers about the treatment cycles. Try to get a book or two about hot tin dipping. Good luck.   Ted Mooney, P.E. finishing.com Inc. - Brick, NJ
