This document is a technical bulletin for Alpha SACX PLUS 0307 and SACX PLUS 0300, lead-free wave solder and rework alloys. SACX PLUS 0307 is designed to replace SnPb and SAC305 alloys, offering improved copper dissolution during rework and lead plating. It features Alpha's proprietary Vaculoy process to remove oxides and reduce slag. The derivative SACX PLUS 0300 is intended for use in solder baths with higher copper content to stabilize the bath.
The bulletin provides technical specifications, recommended wave soldering process settings for single and dual wave processes, and guidelines for managing copper levels and controlling impurities in the solder bath. It also lists recommended maximum levels for various elements such as arsenic, bismuth, zinc, and iron to ensure process reliability and prevent defects.
