One thing though, it is all copper - i.e. not tinned.Will that cause an issue when soldered to tinned components?
No the only issue will be if you leave it un-soldered and the oxides build up meaning it can't be soldered. You do it right away, lets say within a few weeks it will be fine.
I am starting to thinking solid core may be easier to use.What does everyone else use?
Now I'm back at work to check, you can get tinned copper wire from RS (355-079) at a reasonable price.For Thailand check here.
