    Chemposit Sn

    ChempositSnplates a dense, smooth Tin deposit onto copper alloys leaving a corrosion resistant surface that is highly solderable, even when the substrate was not. Chemposit Sndeposits remain solderable for extended periods, (to 6 months) and will not ?Tin Whisker?.Chemposit Sn Immersion Tin plating baths operate more easily and are “poisoned” less readily than other Immersion Tin plating chemistries. Chemposit Sn may be replenished to maintain key ingredients.
