| What should a good gold joint look like? We've run boards for our customers that look kinda dull but seemed to wet properly and the boards fired up just nicely! Should they look nice and shiny like our HASL boards or is "a shiny joint is a good joi

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.
