Does Solder bridge on a strip board matters if it is in the same copper track?
Like i said when i am soldering on the strip board i always make bridges but these bridges are on the same copper track.Does it matter?

 

does it matter? No.
If it does not short two or more tracks together it is usually not referred to as a bridge. By any name, some extra solder on a track will lower the track's resistance some, which is usually a good thing.
