EDXRF Analysis of Lead, Cadmium, Silver, Copper in Lead-Free Solder Materials

Introduction

X-ray fluorescence analysis can be used to quickly and easily analyze samples in solid, powder, and liquid states nondestructively, and is therefore widely used as a screening technique for compliance with the RoHS/ELV directives. A large amount of lead-free solder is used for surface-mount circuit boards. Here we evaluated the sensitivity of analysis of Pb, Cd, Ag, and Cu in lead-free solder reference materials certified by the Japan Society for Analytical Chemistry, and reported those results.
