Is 63/37 no clean solder the way to go for circuit board soldering?

Thank you

Hey herb 63/37 is a good solder with about a 0.45 (1mm) diam,personaly I use a 60/40 rosin core with a .032 diameter,it's a hair thinner but there both very good solder's but make sure it has a rosin core and as far as the no clean I would clean it any ways.
