New SN100CV solder paste from Nihon Superior at SMTAI reduces voiding

Sep 18, 2018

Nihon Superior Co. Ltd., an advanced joining material supplier, today announced plans to exhibit in Booth #511 at SMTA International, scheduled to take place Oct. 16-17, 2018 at the Donald Stephens Convention Center in Rosemont, IL. The company will showcase the new SN100CVTM P608 D4 solder paste, NS-F851 rosin-based flux, ALUSAC-35 alloy and Alconano Nano-Silver paste.

SN100CVTM P608 D4 is a completely halogen free, lead-free, no-clean solder paste. 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 paste provides excellent wetting and reduces voiding.

Nihon Superior’s NS-F851 is the improved version of the NS-F850 rosin-based flux for lead-free wave soldering. The new, no-clean flux ensures excellent wetting of all PCB and component substrates to deliver maximum through-hole fill and facilitates the solder drainage that ensures minimum bridges and icicles. It is the ideal flux for lead-free wave soldering. Additionally, the rosin-based flux ensures that the full reliability potential of SN100C lead-free solder is realized.

ALUSAC-35 is a lead-free alloy designed for soldering aluminum. 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.

Nihon Superior continues to offer solutions to the challenges facing the electronics industry, such as improvements in reliability, thermally stable joining, and lead-free die attach.

Nihon Superior was founded in 1966 when it began marketing unique flux products imported from the US. The company made its mark on society by gathering the most advanced soldering and brazing technologies and products from around the world, and supplying them to companies in the metal-joining industry. A turning point for the company came when it started developing its own soldering materials and with the success of its unique SN100C lead-free solder alloy Nihon Superior has become a major player in the global market. To support the growing demand for its products, Nihon Superior has established manufacturing and sales centers in Japan, China and other Asian countries, and the United States, and formed business partnerships with companies in other markets.
