Abstract

A manufacturing method for a material increases the effectiveness of a component so the component can be present in an amount which does not produce undesirable effects. A material is prepared containing the component in a first concentration. The component is at least partially removed to lower the concentration of the component to a second concentration. The concentration of the component may then be increased to a third concentration above the second concentration.

Claims

exact text as granted — not AI-modified
1 - 18 . (canceled) 
   
   
       19 . A method of manufacturing a solder alloy comprising:
 preparing a molten solder composition containing a component in a first concentration; and then   removing at least a portion of the component from the molten solder composition to reduce the concentration of the component throughout the molten solder composition to a second concentration of at most 5 ppm.   
   
   
       20 . A method as claimed in  claim 19  wherein the first concentration is 10-100 ppm. 
   
   
       21 . A method as claimed in  claim 19  wherein the component comprises a deoxidizing component. 
   
   
       22 . A method as claimed in  claim 19  wherein the component comprises P. 
   
   
       23 . A method as claimed in  claim 19  wherein the component comprises Ge. 
   
   
       24 . A method as claimed in  claim 19  wherein the component comprises Ga. 
   
   
       25 . A method as claimed in  claim 19  wherein the second concentration is substantially 0 ppm. 
   
   
       26 . A method as claimed in  claim 19  including reducing the concentration of the component by bubbling an oxygen-containing gas through the molten solder composition. 
   
   
       27 . A method of manufacturing a solder alloy comprising:
 preparing a molten solder composition containing a component in a first concentration; and then   introducing an oxygen-containing gas into the molten solder to remove at least a portion of the component from the molten solder composition to reduce the concentration of the component throughout the molten solder composition to a second concentration.   
   
   
       28 . A method as claimed in  claim 27  wherein introducing an oxygen-containing gas comprises bubbling gas through the molten solder composition. 
   
   
       29 . A method as claimed in  claim 27  wherein the component comprises a deoxidizing component.
