Is soldering flux necessary?
Yes, solder can be used without flux. To do so, you will need something other than flux to break down the oxides on the metal surface, without which your surface may be damaged or not properly cleaned.
Does soldering increase resistance?
Tin (the main component of most solder) has about 5 times the resistance of copper. The resistance creates heat at the joint, which melts the solder, which increases the resistance until it fails altogether.
Can too much solder be bad?
Too Much Solder It is entirely possible that this blob of solder wets neither the pin nor the pad and is not a reliable electrical connection. The best evidence of proper wetting (and good electrical contact) is a nice concave surface as on the joint on the far left.
What kind of solder do you use to make jewelry?
I find that the flux-to-solder mixture varies, depending on how long the paste has sat on a shelf. For best results, empty the applicator, mix the paste thoroughly, and then put it back into the applicator or a small, lidded glass container. I prefer wire solder.

What do you need to know about flux solder?
Lead-free solders are available for electronics that need to meet health and environmental requirements. And flux solders contain a rosin reducing agent at the core that is released during soldering removing oxidation from the bonding site.
