Current Status and Future Plan of the Viscosity Measurement for the Lead-Free Solder

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.
