How did you come to the conclusion that you are having a cold joint problem. Just by appearance ? As Dave stated if you have any of the metals that he listed in the joints they will appear to be dull and grainy sometimes. But... Dave, I will have t

Hi , It looks like there is solder (shiny like mirror surface). Defently not black and not gold. Regards Mark

While experienced inspectors may be able to determine the aesthetic differences between a lead-free PCB assembly and a tin-lead version, one cannot rely on the "experienced eye". "Less wetting out to the pad edges" (Figure A) and "graininess and lack of shininess of the solder joint" (Figure B) are typical comments about some lead-free solder joints. However, in cases where a Nitrogen atmosphere was present during the reflow of the solder joint (Figure C), there will be little visual differences between the lead free alloys and their tin-lead counterparts.
