HASH(0x9b59f7bc) out of 5 stars Good Economical Electrical Flux 4 Oct. 2013
By Charles W. - Published on Amazon.com
Item Package Quantity: 1 Verified Purchase
The purpose of flux in soldering is to help clean away the oxides and impurities on the metal so that the solder will stick smoothly and reliably. Most electrical wire solder has flux in the core of the solder which is generally adequate if the metal surfaces to be soldered are bare and shiny clean. You need to use a flux like this if the solder has no flux or if the leads or surfaces to be soldered are a bit tarnished. Ideally you prepare the items to be soldered by cleaning and scraping them to clean bare metal before soldering.

When you are working with older components and wires it is advisable after the initial prep to apply flux to the items to be soldered - typically I use a single small drop of flux from a small squeeze dropper bottle for a small wire connection. Then solder as normal. Part of the flux will boil away during the soldering and also clean the joint being soldered. After the soldering is complete I use a paper towel or tissue dampened with alcohol to remove the flux residue. The post-soldering cleaning is partly for a nice appearance and partly so you can see the state of the soldered joint - you want it to be smooth and shiny.

I like the flux because it does a good job for electrical soldering (never, ever use acid flux or acid flux solder with electrical soldering). The flux makes it easier to solder slightly tarnished wire and components. And the flux has a minimal smell when soldering. The flux residue cleans up easily with rubbing alcohol. And this size bottle should last you a very long time - making it quite economical. I recommend dispensing the flux with a small plastic dropper bottle with a narrow spout.

HASH(0x9b59fa08) out of 5 stars This is what you've been looking for 24 Jun. 2014

I work in an electronics factory as a repair technician. I work with rosin flux (liquid and pen) often. MG 835 is excellent stuff, superior (in my opinion) to the stuff used in our manufacturing process. I am extremely satisfied with this purchase and will buy again (should I use the entire bottle within my lifetime)

Some general flux FYI:
- This flux is very thin liquid, and will pour easily.
- As it is rosin-based (essentially filtered tree sap) it is extremely sticky and has quite a pungent odor.
- If exposed to air it will dry into a hard layer.
- If you spill it you will never be able to completely remove the mess.
- A mixture of 1 part acetone to 1 part isopropyl alcohol acts as an excellent flux thinner/remover.

HASH(0x9b59f9cc) out of 5 stars Seriously, buy this flux. 13 April 2013

Unless you specifically need a different kind of flux, buy this. It works quite well (does leave a bit of a sticky residue, but that's easy enough to deal with with some rubbing alcohol and cotton swabs) as a flux, tacks down surface mount components quite well, and is an unbelievable bargain.

I got this for about 1.5 times the price of what most sellers wanted for 1-4 oz of flux, and this might actually be a lifetime supply for me. Unless you literally just need flux for one project, get this stuff. You won't be disappointed.

(Do note: This is flux for electronics soldering, not plumbing soldering. For plumbing soldering you would want an acidic flux instead of a non-corrosive rosin flux.)

HASH(0x9b59ffa8) out of 5 stars A great product for diy electronics 24 Mar. 2013
By Constant Interest - Published on Amazon.com
Item Package Quantity: 1 Verified Purchase
This stuff performs as described. MG provides the same product in a felt tipped pen, and that's convenient. The price "per use" however favors the bulk bottle by a wide margin. I'm using a small pen type oiler for small applications and an ink cartridge filling syringe for larger stuff. I use the syringe to fill the pen oiler. A small note: a little of this stuff goes a long way, but no amount will make up for the need to have clean surfaces before you start.

HASH(0x9b59fd5c) out of 5 stars Works well, I uee it on circuit boards, and most things that need some extra flux 29 Aug. 2013
By Joseph M. - Published on Amazon.com

The usual way I get flux is from my solder. I might be unsoldeirng something, and flux works well in that process as well as the reverse. I would put a small dab of flux cored solder, on my work to aid in removing a part. I'm probably not alone in that area, as flux makes a solder sucker work well, as well as getting solder to stick to things. The majority of the time the flux is to get solder to flow smoothly. if you use your solder to get enough flux, you might find that by the time you get enough flux, you have way more solder than you wanted. So that is where dabbing a little of this Rosin flux on the connection with a Q-tip always makes the task go much smoother. Yes, I use Q-tips on my bench for a lot of things, including to wipe alchol on one little spot to loosen dried flux, then use the other dry end to clean it up.
I have some other flux that I swear will let you solder to things that you never thought was possible. It's Pink, so you will know it when you see it, and I bought it in Amazon too. I just can't remember what it's called, but get the big bottle when you do, you will want to have it around for those really tough soldering jobs.
