Weller Soldering Tip #5

by Andy on June 26, 2008

When using pre-tinned devices and HASL (Hot Air Solder Leveling) or OSP (Organic Solderability Preservative) on PC Boards, using a very active rosin core solder is not necessary. Using a high activity level flux works well on heavily oxidized metals such as bare copper or other non-tinned or non-plated metals, but is not readily suggested for standard electronic assemblies. Use a flux that is designed for the metals that are being joined and keep the activity level to a minimum to help extend tip life.
