Pretty basic question but I am struggling to find the words to get the correct search result. The soldering iron I bought came with very narrow tips that I think are supposed to be used for circuit boards and components.
When I attempt to solder lines from a USB cord together the line never gets warm enough.
I remember in the past soldering copper lines together from an appliance with no issue so I don’t think I’m doing anything wrong in terms of technique but who knows?
Are you using leaded or lead-free solder? If it’s lead-free, it has to be hotter and you may also find extra flux helps.
Thanks for the suggestion. I ended up using both of those when attempting this and ended up with a lumpy cold solder looking connection.
Without the the flux I wasn’t able to heat the line enough to get the solder to melt.
