Laird RF Shields with discoloration on the material

RF shields ideally would have a shiny, tin-plated material. However, due to the manufacturing process, the RF shield may appear discolored, as seen in the examples below.

Laird has reassured us that this discoloration is a phenomenon resulting from the friction between the raw material and tooling during the stamping process. Since the tin plating is a soft material, this friction can affect its shine. The discoloration won’t impact the form, fit, or function of the product.
