Abstract:

The viscosities of the lead-free solders are important to simulate the process of the manufacturing process. In this article, current status of the viscosity measurements for the lead-free solders are reviewed. In addition, we introduced the current work of the viscosity measurements for the lead-free solders by using the rotational viscometer with concentric cylinder spindle geometry.
