摘要： The occurrence of partial chip detachment is reduced by improving wettability for increasing the bonding strength, and by enabling gradual melting of the solder. Solder material, electronic components, and electronic circuit boards with higher performance and higher reliability are offered. The surface of a solder core, lead-frame surface and electrode surface of electronic components, and copper (Cu) land surface of electronic circuit boards are coated with metal element, which is either indium (In) or bismuth (Bi).

摘要： A lead-free solder material is provided, which shows a high thermal fatigue resistance and is able to effectively reduce occurrence of connection failure that would cause a function of a product to stop.A solder material comprises 1.0-4.0% by weight of Ag, 4.0-6.0% by weight of In, 0.1-1.0% by weight of Bi, 1% by weight or less (excluding 0% by weight) of a sum of one or more elements selected from the group consisting of Cu, Ni, Co, Fe and Sb, and a remainder of Sn. When a copper-containing electrode part (3a) of an electronic component (3) is connected to a copper-containing electrode land (1a) of a substrate (1) by using this solder material, a part (5b) having an excellent stress relaxation property can be formed in the solder-connecting part and a Cu—Sn intermetallic compound (5a) can be rapidly grown from the electrode land (1a) and the electrode part (3a) to form a strong blocking structure. Thus, even in a severe temperature environment, cleavage can be prevented from generating and extending, a high thermal fatigue resistance can be attained, and occurrence of connection failure can be reduced.
