Frequently asked questions
Is this solder lead-free?
No. The 63/37 alloy is tin-lead. Work in a ventilated area, avoid touching your mouth while soldering, and wash your hands afterwards.

Yes, the listing positions it for fine-pitch SMD, FPC and micro-wire work. Use a fine tip, a moderate iron temperature and short contact times to avoid lifting pads.
