1. Product Overview
Sn63/Pb37 Electropure™ is a eutectic solder alloy composed of 63% tin and 37% lead, renowned for its high purity and consistency. Manufactured using AIM’s proprietary Electropure™ process, it minimizes suspended oxides, resulting in reduced dross formation, superior wetting, and smoother solder flow. These characteristics improve solderability, reduce bridging, and ensure stable performance. The product complies with IPC J-STD-006 standards and is valued for both functional and protective applications.

2. Applications
This alloy is widely used in wave soldering, selective soldering, and plating. It is particularly effective as a corrosion-resistant coating and as a reliable base for further soldering. Sn63/Pb37 Electropure is compatible with RMA, no-clean, and water-soluble electronic-grade fluxes, making it suitable for diverse electronic assembly operations.
