Nihon Superior Shanghai to Exhibit at NEPCON China 2012
Nihon Superior Shanghai Co. Ltd. will showcase a new and expanded range of products based on its SN100C silver-free, lead-free solder at the upcoming NEPCON China 2012 exhibition in Shanghai. Included in this expanded product range will be the first of Nihon Superior’s new SN100C Advantage SeriesTM alloys, SN99CN in the form of spheres and the solder paste SN99CN P502 D4.
WhilAlso on display will be Nihon Superior’s next-generation range of completely halogen-free solder paste, flux-cored solder wire and liquid flux. While having no deliberate additions of any halogen (F, C, Br or I), these products still deliver excellent reflow and wetting on all common substrates.
Where halogen activation is acceptable, the new SN100C (551CT) flux-cored wire provides a new level of performance with a reduced incidence of icicles in sequential soldering and rework.
SN100C Series
For situations where voiding must be minimized, Nihon Superior has introduced SN100C P810 D4, which has been formulated specifically to facilitate optimum performance of nitrogen atmosphere vacuum reflow systems. While by itself the vacuum reflow process can be effective in achieving a much lower incidence of voiding than conventional reflow processes, its use with the SN100C P810 can further reduce the residual voiding to less than 1 percent of the joint area. This is particularly important in large area joints to components such as QFN where heat transfer has to be maximized. Wetting performance is not compromised and this paste typically can be reflowed with a profile similar to that commonly used with SAC305 and SAC405 solder pastes with a peak around 240°C.
NEPCON China 2012 is scheduled to take place April 25-27, 2012 at the Shanghai World Expo Convention & Exhibition Center
