What are "quality solder joints."
Are the best ones done with gold, silver, spot welded? What?
Are the poor ones done with lead solder? Not enough or too much heat applied? Not enough time allowed after soldering for proper bond in cooling?
Why are some children's frame equiped with such soft metal on nose pad struts that the can flatten them out between the office door and the car? Why aren't they as on some adult frames strong enough that tools are required to adjust them at all, thus allowing us to make adjustments that stay? Are frames supposed to be so flimsy so the patient's can "adjust" them by themselves?
Any other questions about quality and lack of same? Please feel free to chime in and add to this post.
