While Lead-Free solder is the global standard for RoHS compliance, Leaded solder remains critical for high-reliability sectors like aerospace. This guide compares their technical performance, manufacturing challenges, and how JHYPCB ensures zero-defect assembly for both processes.
For lead-free through-hole assembly, wave soldering still excels in high-volume, wave-friendly designs, while selective soldering shines on dense, mixed-technology boards that demand precise, localized heat and low defect rates. This article explains how both processes work, their strengths and limitations, and when each is the better fit.
