What kind of flux do you use for electronics?
For electronic devices, 3 major types of soldering fluxes are widely used: rosin-core flux (RF), mildly activated rosin (RMA), and water-soluble flux (WSF). In terms of electrical soldering, you should check the compatibility of the flux product with the metals used in your devices.
Should I use water soluble flux?
If you need high reliability for a long term then it is a good idea to use a water soluble paste as it has high activation flux and after cleaning there will be no residue or contamination left on the board.
How do you use flux when soldering electronics?
Use a small paintbrush or your fingers to scoop up a small amount of soldering flux. Spread the flux over the area you will be soldering, making sure to cover the wires fully. Wipe any excess flux off your fingers or brush before soldering. Soldering flux is only corrosive once it is heated up and in its liquid form.
How do you clean water soluble flux?
Water-soluble fluxes are usually washed off with hot water; occasionally a saponifier is added to help the cleaning process. Saponifiers are alkaline, and may be corrosive; they react with the acid residue on the board to form a soap and glycerin, which is relatively easy to wash away in hot water.
Can I use Vaseline as flux?
Vaseline is an “oil” based grease, it has no flux properties. (It WILL do the opposite job of contaminating your joint.) … The trick with flux is not the “feel”, > smell, or taste, but the ability to carry heat.
Can I use tinning flux on electronics?
Electronics soldering flux is used in soldering applications in printed circuit board (PCB) assembly and rework; component lead tinning; and wire tinning. … However, that corrosive acid flux will rapidly degrade wiring if plumbing solder is mistakenly used for electronics.
Is Rosin the same as flux?
In fact, the flux we usually say is a general term. In fact, rosin and solder paste are fluxes. Their use is Increase the reliability of soldering between the solder and the object to be welded during the soldering process.
Why do plumbers use flux?
Flux is used to connect copper pipe. Flux is a compound commonly used in plumbing applications where two joints are connected using solder. This is a process known as “sweating” pipes together. Combined with solder, flux is a key part of the sweating process.
What is water soluble flux used for?
Most high-rel people, traditionally, have used water-soluble fluxes because they’re stronger fluxes, they give a more robust soldering process and they’re easier to clean. Because with rosin, you need to use some sort of chemistry, either a saponifier in a water-based system or another solvent.
Do you need flux to solder electronics?
There is solder is available with flux inside the wire, called flux core solder. Flux core solder has flux in the center of the solder wire. Additional flux is unnecessary for most applications, but using additional flux still may make the solder easier to work with for some tasks.
Can you use too much flux when soldering?
One, using much more than needed will basically drown your joint making it hard to heat to the right temperature, two, flux needs to be removed before a part is returned to service so every bit used that is more than needed makes for more clean up.

What is RA flux?
Rosin activated (RA) flux consists of rosin, solvent, and aggressive activators. RA flux has similar and higher activity than RMA for moderately and highly oxidized surfaces. IPC classification is usually ROM0, ROM1, ROH0, or ROH1. RA flux residue is considered corrosive.
Is rosin flux corrosive?
Rosin activated (RA) flux combines rosin, solvent, and aggressive activators. Activity is higher than RMA for use on oxidized surfaces. RA flux is corrosive so sensitive assemblies must be cleaned as soon as possible with a compatible solvent or risk damage to electrically conductive performance.
