" Last but not least, lead-free solder complicates visual inspection, making it harder to reject bad connections at the factory." I x-ray every soldering job out of the oven and off the irons where I work, and that's a TINY LED company. Visual inspections of solder joints can be very unreliable no matter which solder is used.
