Nihon Superior Co. Ltd will exhibit at NEPCON Japan, scheduled to take place Jan 13-15, 2016 at the Tokyo Big Site. During the show, the company will showcase newly developed products that offer improvements in reliability, thermally stable joining, and lead-free die attach.

SN100CV P506 D4 is a lead-free, no-clean solder paste with its basic composition of (Sn-Cu-Ni+Ge+Bi). This new alloy has an addition that enables thermally stable solder joints even after thermal cycling. Unlike silver-containing alloys that derive their strength from a dispersion of fine particles of eutectic Ag3Sn, SN100CV gains its strength from solute atoms in the tin matrix of the joint. The unique ability of SN100CVP506 D4 to survive long-term storage at room temperature allows simplification of stock management while meeting all the requirements of modern reflow soldering processes.  The SN100CV alloy is also available as a completely halogen-free solder paste, SN100CV P604 D4 and a low residue paste, SN100CV P820-5 D4.

Despite the cost and the performance advantages of aluminum, its commercial adoption has been slow because of the concern about the galvanic corrosion that results from differences in the electrical potential of the constituent phases. Joints to aluminum made with this new alloy retain reasonable strength even after 30 days of saltwater immersion.

Alconano Nano-Silver Paste is based on a patented technology that makes it possible to effectively join most metals as well as Si and SiC at low sintering temperatures, if necessary in nitrogen, without the nitrous or sulphurous residues that are the by-products of the sintering of some other nano-silver pastes. The highly active surface of the nano-silver particles and the consequent strong capillary forces make it possible to achieve strong bonds even on copper with high electrical and thermal conductivity at low temperatures without the need for external pressure.
