    Abstract: A cream solder obtained by kneading an Sn—Ag—Cu alloy together with a flux, wherein the Sn—Ag—Cu alloy includes a mixture of a first powdery alloy and a second powdery alloy, the first powdery alloy is represented by an Sn—Ag phase diagram having a solid-liquid coexistence region and has a given silver amount which is larger than that in the eutectic composition (3.5 wt. % silver), and the second powdery alloy has a silver amount which is that in the eutectic composition (3.5 wt. % silver) or which is close to that in the eutectic composition and is smaller than that in the first powdery alloy. This cream solder has excellent strength and thermal stability, and satisfactory bonding properties. It is based on an inexpensive Sn—Ag—Cu solder alloy. It is suitable for use as a high-temperature-side lead-free solder material conformable to temperature gradation bonding. Also provided is a method of soldering.

    Abstract: A surface mount adhesive includes an epoxy resin, a curing agent, an accelerator, a first filler, and a second filler. The second filler has a specific gravity 1.1 to 3 times that of the first filler, and the second filler has a hardness higher than that of the first filler. The first filler has a largest particle size of 1 to 100 μm, and the second filler has a largest particle size of 1 to 100 μm, a specific gravity of 1.7 to 4.5, and a revised Mohs hardness of 2 to 12. The weight ratio of the first filler to the second filler is from 1:3 to 3:1, and the surface mount adhesive has a specific gravity of 1.2 to 1.5. When the surface mount adhesive is dispensed, dispensing failures are suppressed, and dispensing stability is improved.
