Frequently Asked Questions
Why use a master alloy instead of pure Germanium? +
Pure Germanium has a very high melting point and struggles to dissolve smoothly into lower-melting tin. Using this master alloy prevents solution and segregation issues, ensuring an even mix throughout your batch.
What is the mechanism behind the anti-drossing effect of Germanium? +
Germanium has a much higher affinity for oxygen than tin does. When added to the bath, the Germanium preferentially oxidises and migrates to the surface, forming an ultra-thin, invisible protective oxide layer. This barrier blocks atmospheric oxygen from contacting the molten tin underneath, drastically suppressing dross formation and reducing metal waste during wave soldering.
Does each batch of Tin Germanium Master Alloy come with a Certificate of Analysis (CoA)? +
Yes. Every single batch is fully tested and supplied with a detailed Certificate of Analysis (CoA). This analysis report provides the exact elemental breakdown and trace impurity measurements, ensuring full traceability and verified compliance for RoHS and REACH regulated electronics manufacturing.
What is the recommended method for adding SnGe master alloy to an active solder bath? +
The 1 kg sticks should be introduced directly into the molten solder wave or static bath when it is at normal operating temperature. Because the master alloy utilizes a high-purity tin base, the sticks will dissolve smoothly and rapidly distribute the Germanium evenly throughout the bath without requiring excessive stirring or overheating.
