New solder paste at SMTA International
Nihon Superior is to exhibit at SMTA International and will showcase its SN100CV P506 D4 lead-free alloy which provides faster wetting and increased spreadability over SAC305 - which is beneficial in wave soldering and hand soldering applications as well as in reflow.
SN100CV P506 D4 is a lead-free, no-clean solder paste with a basic composition of (Sn-Cu-Ni+Ge+Bi). This new alloy has an addition that enables thermally stable solder joints even after thermal cycling. 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 unique ability of SN100CVP506 D4 to survive long-term storage at room temperature allows simplification of stock management while meeting all the requirements of modern reflow soldering processes.
