Solder de-flux

[Antonio Guerrieri]

	Hi All,

	I'm surprised to discover (see the last post) how the solder flux
can generate faults in electronic boards: in the past, I did never
experiment this.
	Hoping to be not much repetitive in this list, can someone suggest
me all the tricks to avoid any problem with solder flux?
	Thank you in advance for any reply.
	Best regards,

	Antonio

P.S. Can I have problems of these kinds also soldering discrete items like
jacks? do someone think that sometime the solder flux can isolate or
increase the resistence of the electric contact in soldering jacks? in the
positive case, how to avoid this?
