Aspects of the invention provide solder compositions which include two
different fluxing agents. One of the fluxing agents promotes melting of a
metal of the solder at a first activation temperature and the other
fluxing agent promotes melting of the metal at a second activation
temperature that is higher than the first activation temperature. This
dual-flux solder may be used in manufacturing microelectronic components
and microelectronic component assemblies. In one specific application,
the solder may be used to manufacture a flip chip or other
microelectronic component which includes self-fluxing solder balls. This
can obviate the need to apply another flux composition to the solder
balls prior to a subsequent component attach reflow operation.
