Wave soldering remains one of the most critical process steps in through-hole and mixed-technology PCB assembly. Getting it right — consistent solder joint quality, stable thermal profile, minimal defects — requires not just the right machine, but the right configuration for the board type, production volume, and factory environment. This case documents an installation of Sanco’s ISC-450 Lead-Free Dual Wave Soldering Machine at an electronics manufacturer in India, along with the curing oven configuration that completed their production line.
