    摘要: [Problem]Mobile electronic equipment is often dropped during use or transport, and the soldered joints of electronic parts sometimes peel off due to the impact when dropped. In addition, they undergo heat cycles in which internal coils, resistors, and the like generate heat and soldered joints increase in temperature during operation of electronic equipment and cool off during periods of non-use. With a conventional Sn—Ag base lead-free solder, the impact resistance and resistance to heat cycles of minute portions such as solder bumps were not adequate. The present invention provides a lead-free solder alloy, bumps of which have excellent impact resistance and resistance to heat cycles. Means for Solving the Problem The present invention is a lead-free solder alloy comprising 0.1—less than 2.0 mass % of Ag, 0.01-0.1 mass % of Cu, 0.005-0.1 mass % of Zn, and a remainder of Sn, to which Ga, Ge, or P may be added, and to which Ni or Co may be further added.

    摘要: The present invention provides a Sn—Zn based lead-free solder which can prevent peeling of solder from soldered portions even after the passage of long periods after soldering of portions to be soldered made of Cu. A Sn—Zn based lead-free solder according to the present invention comprises 5-10 mass percent of Zn, a total of 0.005-1.0 mass percent of at least one substance selected from the group consisting of Au, Pt, Pd, Fe, and Sb, optionally a total of at most 15 mass percent of at least one substance selected from the group consisting of Bi and In, and a remainder of Sn. This Sn—Zn based lead-free solder can be made into a solder paste using a rosin flux containing a halide such as an amine hydrochloride as an activator.
