The low solids content and activator system results in LOW RESIDUE left on the assembly after soldering. There are no residues to interfere with electrical testing. Kester 186 flux exhibits improved soldering performance to minimize solder bridges (shorts) during rework operations. Review: Works Great on Copper Clad Circuit Boards - Kister 186 Liquid Soldering Flux worked will in my last project. It would be nice if it came with an applicator. I used a cotton swap to apply it to the work. Review: If you use solid solder or re-work antique electronics, this is the great stuff! - In active retirement I repair and restore great old ham radio equipment and antique old radios. The old solder is often so oxidized it won't flow and stick well when parts are replaced. In addition to using new rosin solder, a bit of this flux on the joint to be re-worked makes all the old solder receptive to accepting the new solder, to adhering to braided solder (wick) remover, and to make a good, strong, well-flowed joint. It works great for me! It's supposed to be non-corrosive, but just in case, removing any excess is a great idea! ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01MR49JY1 | | Best Sellers Rank | #44,373 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #97 in Solder #175 in Soldering Parts & Accessories #731 in Welding Equipment & Accessories | | Customer Reviews | 4.6 4.6 out of 5 stars (1,030) | | Date First Available | January 9, 2017 | | Item Package Quantity | 1 | | Item Weight | 2.56 ounces | | Manufacturer | Kester | | Material | copper | | Package Dimensions | 6 x 4 x 4 inches | | Part Number | 186-2 | ## Images ![Kester 186 Liquid Soldering Flux, RMA Rosin, 2-ounce Bottle - Image 1](https://m.media-amazon.com/images/I/61nmi5QuCJL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works Great on Copper Clad Circuit Boards *by G***R on August 28, 2026* Kister 186 Liquid Soldering Flux worked will in my last project.

Not much can be said about the actual product as Kester brand is always top notch. i got both this 186 and the 959T for my needs and that will cover pretty much everything i do. BGA, SMD and through-hole (re)work. I don't use the nozzles that are included, i use acid brushes. but i did test them and they are ok, can be a bit overkill if you don't take your time. my best advice is use a brush. The only thing i wish the seller would do is carry some bigger size refills. hint hint... LOL TLDR; This stuff is great, it does what it is supposed to do and I've never had an issue with it. The seller was AWESOME! Shipping was Great.
