I think it is "intermetallic compound"

Intermetallics or intermetallic compounds :

In the High Temperature soldering process [e.g. Reflow process & wave soldering process] , some undesirable side-products [ which form the alloy合金 i.e. 杂质 ]were produced which will affect the solder 's workmanship ( i.e. solder workmanship may be rejected per IPC-A-610 ) .

Such undesirable side-products [ i.e. Alloy合金 / 杂质] will cause several defect : Insufficient Solder [ 少錫] , No Solder, Dull color ...etc.

http://en.wikipedia.org/wiki/Intermetallics

Intermetallics or intermetallic compounds is a term that is used in a number of different ways. Most commonly it refers to solid state phases involving metals. There is a "research definition" adhered to generally in scientific publications, and a wider "common use" term. There is also a completely different use in coordination chemistry, where it has been used to refer to complexes containing two or more different metals.

Although the term intermetallic compounds, as it applies to solid phases, has been in use for many years, its introduction was regretted, for example by Hume-Rothery in 1955. [1].
Note that many intermetallic compounds are often simply called alloys, even though strictly speaking they are not. For example Complex metallic alloys are intermetallic compounds with large unit cells.

Intermetallics involving two or more metallic elements

Intermetallic compounds are generally brittle and high melting. They often offer a compromise between ceramic and metallic properties when hardness and/or resistance to high temperatures is important enough to sacrifice some toughness and ease of processing. They can also display desirable magnetic, superconducting and chemical properties, due to their strong internal order and mixed (metallic and covalent/ionic) bonding, respectively. Intermetallics have given rise to various novel materials developments. Some examples include alnico and the hydrogen storage materials in nickel metal hydride batteries. Ni3Al, which is the hardening phase in the familiar nickel-base superalloys, and the various titanium aluminides have also attracted interest for turbine blade applications, while the latter is also used in very small quantities for grain refinement of titanium alloys.
