What type of flux should be used in 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.

What is the best solder for automotive wiring?
Use rosin core solder; the center contains flux that cleans the surface of the wire to be soldered. Solder is often a combination of mixed alloys. Automotive applications use 60/40, containing 60% tin and 40% lead.
Can I solder without flux?
It’s ok, if you can do it, but it’s very difficult to solder without flux. The flux breaks down the oxide layers on the metal surfaces and allows the solder to “wet” them. If it doesn’t wet, it doesn’t make a connection. … It’s normally always necessary to use flux when you solder.
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.
Why is solder so expensive?
Small diameter solder always costs more forma given weight. Unfortunately with modern components you need to buy very small diameter solder for hand soldering. Yes, as the diameter decreases the price definitely increase.
Does solder go bad?
Kester has this to say, in their policy about shelf life: Flux cored solder wire has a limited shelf life determined by the alloy used in the wire. For alloys containing more than 70% lead, the shelf life is two years from date of manufacture. Other alloys have a shelf life of three years from date of manufacture.
Can I use lead free solder for electronics?
The main types of solder are lead and lead-free. You can use both for electronics, but it can be easier to work with lead-based solder. Make sure to stay away from acid core solder as this is intended for plumbing, NOT electronics. … Lead-Free Solder Rosin Core.
Is it better to crimp or solder?
Crimping offers stronger, more reliable connections than soldering. Soldering uses heated metal to join the cable to the connector. Over time, this filler metal will degrade, which may cause the connection to fail. Most electricians will agree that crimping is also easier than soldering.
Is it OK to solder electrical wires?
The reason is that solder is a very good electrical connection, but a very weak mechanical one. Copper (or aluminum) alone can bend, flex, and even stretch a bit without any damage, so it’s suitable for things that move around a bit. Solder is very brittle and will crack and break if you try to flex it.
Does solder increase resistance?
Tin (the main component of most solder) has about 5 times the resistance of copper. As such, when used in high current applications (think a battery lead), that resistance can lead to heat. … The resistance creates heat at the joint, which melts the solder, which increases the resistance until it fails altogether.
Do I need flux to solder wires?
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 I use Vaseline instead of flux?
Vaseline is an “oil” based grease, it has no flux properties. (It WILL do the opposite job of contaminating your joint.) > >
