yes. the metals present (including % composition) is: - 40% lead - 60% tin
with solder
Yes, usually no problem. If you know how to solder, then solder away.
In some solder it is. But even if it is in the solder you should still use flux.
Yes: flux core solder is. No: acid core solder is not.
Solder is a metallic alloy
solder is use for to make jewles
Depends on the kind of solder.
Solder is a fusible alloy that is used to join less fusible metals or wires,Combinations of tin and lead are most common, in ratios of 60 percent tin to 40 percent lead; 63 percent tin to 37 percent lead; and 50 percent tin to 50 percent lead.
Six types of bad solder connections include a cold joint with insufficient wetting (Pin) or insufficient wetting (Pad), a disturbed joint, an overheated joint, too much solder, or not enough solder.
A reel of solder used for joining electrical circuits together on circuit boards. Solder is made of a mixture of tin and lead and sometimes has has flux (a form of acid) in the core of the solder to ensure a clean surface for the solder to flow into.
