That's got to be one of the most inane statements I've ever heard.
Obviously, you have no idea of the function of solder in electrical circuits.
No, I don't have any understanding of this subject.
Unless you want to factor in I built an amp from two table radios in '63, sold stereos in the 60's, 70, and the 90's, Trained on microwave radio in the air force (think klystrons and wave guide), was certified in mil spec soldering, and did semi-pro sound for various churches in the area for about 20 years.
Yeah, I guess I'm not qualified to answer your silly questions.
