Questions tagged [flux]

Refers to flux chemicals used in soldering. Use the magnetic-flux tag when referring to magnetic field changes.

Flux facilitates processes. To solder joints with impurities like dirt, oil or oxidation, the flux allows the solder flow and stick to the underlying metal. Some fluxes go beyond the simple prevention of oxidation and also provide some form of chemical cleaning (corrosion).

Where does the flux go when desoldering?

I have a piece of equipment with a right angle miniUSB port that went bad. After pulling the old port I have a big blob of solder shorting out the traces. So obviously I must get rid of the blob before I solder in a new port. The main question is…

Storing liquid soldering flux long-term. Is it light sensitive?

Is soldering flux known to be light sensitive? I got a big jug but the big jug it arrived in is deformed and doesn't look like it's going to hold so I am going to transfer it over to some bottles for long term storage (I don't use that much and so…

Residual flux conductivity on PCBs causing problems?

The question here is how much flux remains on boards under normal manufacturing conditions, how conductive is it, and does the conductivity change with humidity and temperature. I know that for super sensitive electrometer amps the recommendations…

Will my wires have current stability issues?

first post here. I'm currently making a set custom sleeved/crimped cables for my computer's modular power supply, and my crimper isn't very good, so for extra security, I've soldered all the crimps, using flux so that they flow properly. They are…
