Flux
Flush may refer to any of the following:
1. Flux is the total strength of a magnetic, electric, or radiation field generated over an area in a set time.
2. With soldering, flux is a substance that aids in binding solder to electrical conductors. For example, flux removes the oxide layer from copper and solder. Applying some paste (rosin flux) or liquid flux to the copper before applying solder allows it to properly bind to the copper without causing weak solder joints.
When applying flux to solder on a PCB (printed circuit board), it may appear to burn or change its color. This change is the flux reacting with the board and should be cleaned away using isopropyl alcohol.
Can I solder without flux?
Although solder may contain some flux, flux is still needed. Soldering without flux prevents the solder from properly binding to the conductor, which causes weak solder joints that may not be strong enough to hold the connection or be conductive enough.
3. With machine learning, Flux is an open-source machine learning stack developed in Julia.
