## Overview

MG Chemicals 8342 RA Rosin Flux Paste is a 50g amber jar of high-performance, RoHS-compliant flux designed for both lead-free and traditional soldering.

Its organic acid base ensures easy cleaning of post-solder residues, enhancing efficiency and cleanliness in your workspace.

## Description

The 8342 RA rosin flux paste is superior electronic grade flux paste system. It is designed for lead-free alloys, but it works well with conventional leaded solders as well.

Used for solder touch up, repair, or rework surface mount assemblies via brushing or dispensing.

Review: Good product - I'm really happy that I made this purchase. This product is top of the line and leaves a very clean work area when you do soldering with it. I purchased this because I'd run out of my regular brand so I decided to give this one a try and it actually is better than the one that I used to use. I would recommend this to anyone who does any soldering with PCB boards. Make sure you do have a clean flux cleaner.
Review: Great quality! Like the ones my dad used to have 20 years ago!! - Once I opened the container, the smell told me all I need to know. Perfect quality! I was going to give up on my soldering Iron tip as I couldn't clean the oxidized at all. Tried different method, unsuccessful. This paste cleand it in a matter of seconds. Although it's not good for soldering tips, but sometimes I have to use it. Just keep in mind to keep your soldering iron tip covered with tin to prevent it from corrosion.

### ⭐⭐⭐⭐⭐ Perfect for desoldering
*by V***R on July 25, 2024*

I love this stuff for desoldering through hole components. The synthetic and no clean fluxes on the market just aren’t penetrative enough when mixing unleaded with leaded for through hole desoldering work. This is the only stuff I trust that won’t have me overheating the PCB. Synthetic stuff is great for surface mount but you just can’t beat real Rosin flux for through hole! It does have the downside of having to clean it much more thoroughly but it’s worth it to not be battling different heat settings for different types of solder.
