Nihon Superior to Highlight SN100CV P608 Paste at SMTAI
September 6, 2023 | Nihon Superior Co. Ltd.Estimated reading time: 1 minute
Nihon Superior Co. Ltd., an advanced joining material supplier, is pleased to announce that it will exhibit its SN100CV P608 solder paste in Booth #1415 at the SMTA International Exposition, scheduled to take place Oct. 10-11, 2023 at the Minneapolis Convention Center in Minneapolis, MN.
SN100CV® P608 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. Although silver-free, in tensile tests the SN100CValloy matches the strength of SAC305 while maintaining a high level of resistance to impact loading. For high-reliability applications requiring greater strength than SAC305, the LF-C2 lead-free alloy is available as it uses both dispersion and solid solution strengthening. With a liquidus temperature of 213°C, it can be reflowed at a lower temperature than SAC305.
The P608 flux medium provides wetting comparable with that of halogen containing paste even though it is completely halogen-free. SN100CV P608 and LF-C2 both deliver excellent performance over a wide range of component types and process parameters.
The company will also be displaying its TempSave™ series of low temperature soldering materials. The series is designed to address the industry’s goals of reduced peak reflow temperature to reduce defects contributing to package warpage, reduce energy consumption during the reflow process, and avoid potential damage to temperature sensitive devices. TempSave B58 is a eutectic SnBi alloy with a melting point of 139°C while TempSave B37 is a ductile hypoeutectic SnBi alloy and does not contain Ag.
High bismuth containing alloys are known to be brittle and therefore poor in drop shock performance. However, TempSave B37 has outstanding drop performance, even dramatically outperforming SAC305. The halogen-free P610 flux medium is specifically designed for Bi alloys. The TempSave B37 P610 solder paste can be reflowed with a peak temperature of 190°C. Additionally, a high-speed jetting paste version is available – TempSave B37 P611, which provides consistent dot sizes.
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.

Overview of Soldering Systems With Vacuum
12/18/2024 | Dr. Paul Wild, Rehm Thermal Systems GmbHWhen soldering electronic assemblies, the focus of the vacuum application is on the removal of volatile substances from the solder joints and the associated reduction of pore formation. Particularly in the thermal management of power electronics components, pores can cause so-called hotspots with higher temperatures due to their poor heat conduction. These hotspots can lead to overheating of the components on the one hand and to thermally induced destruction of the solder structure on the other.
