Solder method

A soldering method for soldering electronic components onto a copper (Cu) substrate using a tin (Sn) solder alloy. The method consists in pretreating the Cu substrate by depositing a thin layer of zinc (Zn) before the deposition of the Sn solder alloy. This method greatly enhance the mechanical and...

description A soldering method for soldering electronic components onto a copper (Cu) substrate using a tin (Sn) solder alloy. The method consists in pretreating the Cu substrate by depositing a thin layer of zinc (Zn) before the deposition of the Sn solder alloy. This method greatly enhance the mechanical and electrical properties of the solder alloy, allowing the use of lead (Pb) free alloys such as tin-bismuth (Sn-Bi).
