Why use silver solder? As you have discovered, it is harder to make a good joint. In electronic soldering the quality of the joint is far far more important than which alloy is used.

The silver content 2-4% doesn't make the joint harder to make. Eutectic silver solder melts like butter and gets a nice silver finish to it so you know your joint is perfect. I do not and have never had any issues with silver solder and prefer it over tin/lead or lead free, not even close comparison IMHO. I do a fair amount of soldering.. probably every day or almost every day for several years.

Cheers,
Bob

So using silver solder has the advantage that an experienced solderer using the right equipment can produce bad joints which look exactly like perfect joints?
