Nihon Superior�s SN100C Wins 2008 SMT China Vision Award

OSAKA, JAPAN � April 2008 � Nihon Superior Co. Ltd., an advanced lead-free soldering materials to the global electronics industry announces that it has been awarded 2 2008 SMT China Vision Award with Balver Zinn in the category of Soldering Materials for its innovative SN100C Paste. The awards were presented to the company during an April 8, 2008 ceremony that took place at the Shanghai Everbright Convention & Exhibition International Hotel during NEPCON China/EMT China.

With its unique tin-copper-nickel-germanium alloy SN100C now firmly established as one of the global electronics industry�s most popular lead-free wave soldering alloys. It has also been found its properties make SN100C an ideal choice for reflow and hand soldering applications.

The fluidity of SN100C, which is comparable to that of tin-lead, is one of the factors that contribute to excellent hole fill and minimal shorts in wave soldering. However, that property is also an advantage in hand soldering where, in combination with the right core flux , it makes possible the completion of more than 35 average joints per minute with a tip temperature of only 380�C. Nihon Superior is now offering the eCore low-spatter lead-free flux-cored solder wire.

The 227�C melting point of SN100C was first thought to preclude its use in reflow soldering but when it was noted that tin-silver-copper alloys (such as SAC305 with a melting point of 217-218�C) are typically reflowed with a peak temperature around 240�C, it was realized that SN100C could be a drop-in replacement. Its high fluidity and excellent wetting properties mean that SN100C can be reflowed successfully at a lower superheat above liquidus than SAC alloys. Nihon Superior now offers SN100C no-clean ePaste for general reflow purposes.

The SMT China VISION Awards program is sponsored by SMT China Magazine and honors the top categories of various manufacturing-related products, materials and equipment. The purpose of this program is to recognize, reward and celebrate excellence in the Asian electronics industry.
