- No, my papers are not yet postet on a web page ( too much work, maybe too
lazy )
- I am working at the Swiss Federal Institute for Materials Testing and
Research. This is not a company but a research institute which is part of
the Swiss Polytech in Zurich ( ETHZ ).
- The 2% silver have their reason in the Ag/Pa connectors of some SMT
components. The silver in the solder is supposed to slow down the
dissolution rate of the connector's silver. Metallurgically Sn62Pb36Ag2 is
a ternary alloy with a somewhat lower melting point than the binary
tin/lead eutectic.
