What do you call 'organic flux' ? Do you mean colpphonium (agathis resin) ?

Then I wash it in hot running water and blow dry with compressed air. It gets perfectly clean. You can buy liquid flux of this type also, which makes soldering of small surface-mount parts quite easy. The big caveat here is that you MUST wash off the flux within a day, or it will begin to corrode the circuit board and make conductive paths where you don't want them. -- David Forbes, Tucson AZ -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
