Base material thickness: 0.1mm - 0.8 mm
Reflow Tin Plating: Sn 0.8μm - 2.0μm
Base Material: Brass /Bronze /Copper /Lead Frame
The high demands placed by the automotive, electric and electronics industries on connectors and stamped grids, such as low insertion forces, good anticorrosion protection and good solderability, require the materials used to have surface treatment. Accordingly, copper and copper alloys are coated with a variety of metals, of which pure tin is frequently selected for the surface coating. Pure tin is the first choice as surface protection for all connector and stamped grid materials, not only because of its properties, but also the cost advantage over precious and semi-precious metals.
