SN100C Celebrates 20 Years of Reliability Service


Reading time ( words)

Nihon Superior Co. Ltd., an advanced joining material supplier, plans to exhibit in booth #518 at 2019 SMTA International, scheduled to take place September 24-25, 2019 at the Donald Stephens Convention Center in Rosemont, Illinois. The company will celebrate the achievements produced by the well-known SN100C lead-free alloy. TipSave N flux-cored solder wire will be introduced and SN100CV P608 D4 solder paste will be shown.

SN100C has been widely accepted as a leading lead-free soldering alloy since it was invented by Nihon Superior’s President Tetsuro Nishimura. The silver-free SN100C alloy delivers a stable microstructure in an alloy that can accommodate the long-term cyclic strains and impact loading to which a solder joint can be subjected. The micro-addition of nickel enhances the performance of SnCu resulting in smooth and bright fillets with few shrinkage defects and a stable microstructure with minimal growth of the interfacial intermetallic, ensuring highly reliable solder joints.

The newly developed TipSave N flux cored solder wire extends soldering iron tip life by 3X.  Paired with the (032) no-clean, halogen-free cored-flux, it provides fast wetting and low spattering. TipSave N is a good match for hand soldering as well as continuous robotic soldering as it reduces required soldering tip change overs, increasing production while reducing cost.

SN100CV 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 continues to offer solutions to the challenges facing the electronics industry, such as improvements in reliability, thermally stable joining, and lead-free die attach.

About Nihon Superior Co., Ltd.

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.

SMTA Europe Webinar: What Is a Good Solder Joint, and How Can Solder Joints Be Tested?

11/18/2020 | Pete Starkey, I-Connect007
What is a good solder joint? And how can they be tested not only for purposes of process characterisation, optimisation, monitoring, and control but also for ensuring their long-term reliability? Pete Starkey details a webinar organised by the Europe Chapter of SMTA that was presented by Bob Willis, an expert in soldering, assembly technologies, and failure analysis.

This Month in SMT007 Magazine: Test and Measurement in a Smart Factory

11/03/2020 | Nolan Johnson, I-Connect007
Nolan Johnson spoke with MIRTEC President Brian D’Amico about how the role of test and measurement equipment is changing in the smart factory and how shops can adjust to make use of the new technology. D’Amico shares this insight: “While approximately 90% of U.S. electronics manufacturers recognize the potential of Industry 4.0 to improve productivity, many are slow to adopt smart factory solutions within the manufacturing process.”

Reducing Flux Splatter in Sensors and Camera Modules

10/30/2020 | Jasbir Bath, Shantanu Joshi, and Noriyoshi Uchida, Koki Solder America And Koki Company Limited
With the increased use of electronics in new technology areas, flux formulations are being developed to address the new and existing requirements. For sensors and camera modules used for Advanced Driver Assistance System (ADAS) and internet of things (IoT) applications, there is a demand for no-clean flux formulations in lead-free solder paste, which can reduce flux splattering during reflow.
