A METHOD OF DEPOSITING A TIN LAYER ON A METAL SUBSTRATE AND A USE OF A STRUCTURE COMPRISING A NICKEL/PHOSPHOROUS ALLOY UNDERLAYER AND SAID TIN LAYER WITH SAID METHOD

A METHOD OF DEPOSITING A TIN LAYER ON A METAL SUBSTRATE AND A USE OF A STRUCTURE COMPRISING A NICKEL/PHOSPHOROUS ALLOY UNDERLAYER AND SAID TIN LAYER WITH SAID METHOD

To achieve tin deposits being largely free of pressure induced whiskers, a method of depositing a tin layer on a metal substrate is devised, wherein said method comprises: (a) providing said metal substrate; (b) depositing a nickel/phosphorous alloy underlayer on at least one surface of said metal s...

Zusammenfassung:To achieve tin deposits being largely free of pressure induced whiskers, a method of depositing a tin layer on a metal substrate is devised, wherein said method comprises: (a) providing said metal substrate; (b) depositing a nickel/phosphorous alloy underlayer on at least one surface of said metal substrate; and (c) depositing said tin layer on said nickel/phosphorous alloy underlayer by depositing said tin layer comprising using a pulse plating method.
