AIM signs new lead-free agreements.


AIM, Inc. (Montreal, Quebec, Canada), a manufacturer of assembly materials for the electronics industry, has signed a worldwide license agreement for the company's patented lead-free alloy, CASTIN[TM], with Accurus Scientific Co., Ltd, (Taiwan) and Dyfenco Electronic Chemical Corp. (Kaohsiung Hsien, Taiwan). CASTIN[TM] is a lead-free solder solder (sŏd`ər), metal alloy used in the molten state as a metallic binder. The type of solder to be used is determined by the metals to be united. Soft solders are commonly composed of lead and tin and have low melting points. Hard solders (i.  comprised of tin, silver, copper and a grain-refining and temperature-reducing dopant dopant

Any impurity added to a semiconductor to modify its electrical conductivity. The most common semiconductors, silicon and germanium, form crystalline lattices in which each atom shares electrons with four neighbours (see bonding).
. The solder features a relatively low melting temperature Melting temperature may refer to:
  • Melting temperature, the temperature at which a substance changes from solid to liquid state.
  • DNA melting temperature, the temperature at which a DNA double helix dissociates into single strands.
, offers improved joint strength and inhibits intermetallic growth during high thermal temperature cycling.

The agreement enables Accurus and Dyfenco to manufacture and sell the alloy throughout the world in all solder forms, including solder paste Solder paste (or solder cream) is a mix of small solder particles and flux. It is used extensively in the automated soldering processes wave soldering and reflow soldering. , solder bar, wire solder and preforms.
