Lead-out Plating of Reed Switches

During the reed switch sealing process, Oxides are formed on the leads outside the sealed glass, which needs to be removed. An electro-cleaning and etching process is used to remove the Oxides and the reed switch leads are then taken for lead-out plating with pure Tin. The Tin plating of reed switch leads provides excellent solderability and also prevents the corrosion of the underlying Nickel-Iron leads. If welding of reed switch leads is required, during non-standard lead formations, the Tin plating should be done after this stage. After Tin plating, the reed switch leads are inspected for patches or non-uniform coloring, solderability and uniform Tin plating thickness, and then sent for the next stages of testing.
