Lead vs Lead-Free Solder Alloys – How to Choose for PCB?

Lead vs Lead-Free Alloys for Soldering PCB — What's the Difference for printed circuit boards? Why do Lead-Free joints often crack, and why does NASA still avoid them? In this video, I break down the technical, practical, and real-life differences between Sn63Pb37, SAC305, and low-temperature Bismuth alloys. We’ll look at real scenarios in electronics manufacturing, professional repair, and even home soldering: ✅ How to choose between lead and lead-free solder? ✅ Why overheating isn’t always a problem with SnPb, but is dangerous for SAC305? ✅ When and why microcracks happen in lead-free joints? ✅ Can you mix lead and lead-free solder on one board? ✅ Why Bismuth is only good for desoldering — and dangerous for soldering PCB? ✅ What PCB manufacturers actually use today and why RoHS changed everything? This is a technical, focused breakdown for those who work with electronics and want to avoid costly mistakes in soldering and repair.
