Lead-free eutectic solder paste on show at IPC APEX

The reliable SN100C alloy delivers a silver-free stable microstructure that can accommodate the long-term and impact strains to which a solder joint can be subjected. The eutectic character of the SN100C alloy and the associated high fluidity provides faster wetting and increased spreadability over SAC305, which is beneficial in wave soldering and hand soldering applications as well as in reflow.

SN100C P506 D4 is a lead-free (Sn-Cu-Ni-Ge) no-clean solder paste that can be stored at room temperature for more than 150 days without deterioration. According to Nihon, this material will not only simplify stock management, but also improve productivity with excellent consecutive printability.

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 conventional nano-silver pastes. The highly active surface of the nano-silver particles and the consequent strong capillary forces makes it possible to achieve strong bonds with high electrical and thermal conductivity at low temperatures without the need for external pressure.

Nihon Superior offers a range of products that offer solutions for some of the challenges the electronics industry is now facing, including lead-free die attach, void minimization, environmental protection and process yields.
