Customers like the product. They say it provides consistent results and forms a good base for adhesion of soldiers. The flux is great for IC work and useful when working on complex circuits. It's an excellent dispenser and a great flux pen.

168 customers mention "Flux quality"146 positive22 negative

Customers like the flux quality. It improves the flow of solder, runs smoothly, and makes great solder welds. They say it takes a good squeeze to start a flow, but a firm, even pressure deposits the flux just fine. The flux is thick, so a little goes a long way when melted, and their soldering has improved immensely since using this product.

they changed syringe, its bad now
2 out of 5 stars
they changed syringe, its bad now
They changed the syringe so now the plunger is separate and doesn't stay attached. It's annoying because that means you have to keep track of another piece plastic just to push the flux out. It doesn't make any sense either since the clamshell packaging just got bigger instead of smaller.

    1. The No Clean Flux Paste is an essential tool for professionals engaged in the touch-up and repair of surface mount assemblies. Packaged in a convenient syringe dispenser, it allows for precise application, ensuring efficiency and accuracy in repairs.

    2. Formulated with a unique blend of high-grade synthetic resin and thixotropic agents, this flux paste is specifically designed for use with both high-temperature lead-free and conventional Sn/Pb alloys. It delivers optimal fluxing activity, promoting rapid wetting action and extensive wetting spread.

    3. As a no clean formulation, the residues left behind do not require removal for most applications, making it an ideal choice for streamlined processes. Its excellent wettability, non-conductive, and non-tacky residues ensure compatibility with both lead-free and leaded solder systems, enhancing overall performance in electronic assembly tasks.

    OFC no flux is "zero-clean" regardless of their claims, but this cleans up nicely with high concentration IPA on a toothbrush.

    I've been using a flux pen and other types of rosin flux for a while and none have given me the results that this product has given me. The cheapest of solder wicks will work great with some of this smothered on it before application. I just swapped out every single capacitor on a Vectrex gaming system and this along with a lot of wick Made the job so much easier. Highly recommended.

    5.0 out of 5 stars Effortless Application, Reliable Soldering
    Reviewed in the United States on April 23, 2024
    Size: 0.3 OuncesVerified Purchase
    I recently started using MG Chemicals No Clean Flux Paste for my electronics projects and I'm thoroughly impressed. The paste has the perfect consistency, which makes application easy and mess-free. It significantly improves solder flow, resulting in stronger and more consistent joints. Although it leaves a slight residue, it does not affect the electronics' performance.

    The no-clean feature of this flux paste saves considerable time during soldering tasks. It eliminates the need for post-soldering cleanup, often necessary with other flux types. This is especially useful when working on complex circuits. Additionally, the formula minimizes fume emissions, making it a safer choice for indoor projects.

    4.0 out of 5 stars Super hard to squeeze out of the tube, but works well once you get it applied
    Reviewed in the United States on August 8, 2019
    Size: 0.3 OuncesVerified Purchase
    Like others have mentioned, this flux takes way too much effort to get it out of the tube. It also continues to flow once you break the skin on your thumb pressing so hard and then set it down which gets a bit messy and is somewhat wasteful.

    The plunger does stay attached unlike the chipquik brand.

    Once it is applied, solder flows really well and the residue is easy to clean up.

    Overall, it worked well. The force required was a drag but then again, the chipquik plunger that falls out bothered me too. I am going to try the Kester brand next which is about twice the cost but...

    I have been wanting to solder a wire for a Game Boy screen replacement project I’ve been looking for for quite some time and flux came highly recommended to me by many. This stuff was well priced, it was super easy to clean up with a dab of IPA. The actual function of flux is to help make solder flow easily and better and this stuff performed!

    Finally got a chance to use this flux, been keeping it in the basement fridge since ordering it. It works well and dispenses easily. As shown. Makes rework a lot easier, especially if working really small connections.

    Will order again when I eventually run out of it.

    Used for some retro console mods and repairs and mech keyboards mods and upgrades.

    Please note if it is not stored properly it WILL go thick be very hard to push out of the syringe.

    If it does go thick you can use it like regular solder use a fine toothpick to place it.

    If you want to revitalise it you need to squeeze it out on to a small tub and mix it with solder flux and it’s good to go
