Yeah, the trouble with lead-free solder is that EVERY joint looks cloudy
cold and bad, even if it's good. Very hard to tell if it's a good joint.
A bit frustrating from technician viewpoint.
Different type of product as well. Choose carefully.
When repairing, Mfr A says use this type, Mfr B says use that type.
Leaded solder still available here, but can't be used in new products.
If all else fails, use chewing gum and wrappers, like McGyver!
