Bare and Tin-Plated Copper Strip

Choose the surface finish for the specified solder joint or contact system. For tin-plated strip, define the tin layer and its condition after forming, as well as the base copper grade, temper, dimensions and edge requirements.

Surface-layer schematic, not to scale. Confirm single- or double-sided coverage and hot-dip or electroplating process. Tin coating is separate from the conductor’s core and cladding.

Decision	Bare Copper Strip	Tin Plated Copper Strip	Acceptance basis
Surface	Copper surface of the specified finish	Tin layer over the specified copper substrate	Choose the surface required by the joint or contact system.
Forming sequence	Formed copper surface needs its defined handling/cleanliness	Tin may be applied before or after forming as specified	Check coating thickness, adhesion and cracking after the intended sequence.
Joining	Use the defined preparation and solder/contact process	Use the defined tin finish and solder/contact process	Tin is a process input, not a universal reliability guarantee.
