Cold Solder Joint
A cold solder joint may also result when the board or the soldered wire is moved while the molten solder is still melted. A cold solder junction increases electrical
Why are cold-joint wires prone to breakage
Home / Why are cold-joint wires prone to breakage
A cold solder joint forms when solder fails to melt completely (preventing proper joint formation); it has a rough, rigid, uneven surface, and is prone to cracking, failure, and increased electrical resistance–ultimately reducing the reliability of electronic assemblies. This results in a connection that looks dull, grainy, or cracked, and it often lacks the mechanical strength and electrical conductivity needed for a reliable. Cold solder joints refer to situations where the solder did not flow properly to establish a connection and melted. After a conductor breaks, the remaining wire ends are prone to irregular displacement in a vibrating environment.
