This type of flux is mostly used for surfaces that are clean. It leaves virtually no residue after soldering. Rosin Mildly Activated (RMA) Flux: It has sufficient activator to clean the solder-coated or plated lands and component terminations or leads, thereby enabling the molten solder to wet...
The design of fluxes for a selective soldering application poses unique problems due to the localization of the soldering process. Both the heat treatment and the scrubbing action of the flux residue by the solder wave are confined in the soldered area. To address this specific issue, the flux...
For now, just know that flux is a chemical agent that aids in the flowing of lead-free solder. While it is possible to use lead-free solder without flux, it makes it much easier to achieve the same effects as with leaded solder. Also, because of the added cost in making lead-free ...
Rather than using a hot tip to melt the solder, it is instead melted using hot air. Soldering using a hot air station is a bit more advanced. I recommend getting good with a soldering iron first, because most of what you learn here will be useful to you when using a hot ...

(Side note: A new water-soluble flux core is starting to gain some traction as an alternative to rosin core because it is more environmental friendly.) Summary 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-bas...
Desoldering wick (also known as solder wick, wick, or desoldering braid) is a common method of removing unwanted solder using flux and braided copper wire. It is commonly used to aid in removing faulty components, to correct solder bridging, or for any
Without flux in the solder to clean your surfaces, you would have a very hard time getting the solder to wet. Clean your iron using a brass sponge or a wet sponge to remove any oxidation or excess solder from the tip. Remember to always keep your tip clean while you’re soldering. A...
Bittele discusses how to properly solder an SMD to a PCB pad, including comments on the solder, flux applicator/pen, soldering tool (i.e., iron or pencil), and good soldering technique.
Heat and Solder the Joint– including closeup pics of the proper way to hold the iron against the work. Also, numerous good and bad joint pics. Cleanup– Do you really need to clean off flux residues? Protection– What is a conformal coating? Some applications encase electronics in solid ...
