La-Co 22107 Regular Soldering Flux Paste, 1lbs

Dried out because I left the lid off, it became very crumbly and hard to use.The solution was to stir in vaseline until it was nice and sticky again.

I've been using this stuff at work for 5 years straight.Liked it so much I got a jar for projects at home.A little bit goes a looong way.

Nice product

Good product

I am torch soldering copper jewelry with safety silv 45, I tried two types of fluxes before I found this one, one was 10+ years old and no good, the other was extremely overpriced from the jewelry making section of a craft store and gave the same results. I thought I was doing something wrong, until I tried this one. This works perfectly, and I can't believe how cheap it is. I was shocked that it worked, because I read somewhere on here that it wasn't for silver, but it worked just fine with my silver solder on copper. It makes the metal flow right into place. Be sure to wash it off of any copper it comes into contact with when you are done. I made the mistake of getting it on one of my copper bracelets as I was working and didn't notice untill hours later, now it needs a good cleaning and polishing.Attached is an image of a ring I soldered using this, the metal flowed right into the cracks where it is supposed to be and the joint can barely be seen.

UPDATE 10/23/2019:I TRIED TO USE THIS FLUX TO SOLDER A DCHDMI RIBBON CABLE ONTO A DC MOTHERBOARD, AND EVEN THOUGH THE SOLDERING JOB APPEARED SATISFACTORY, I COULD NOT GET A PICTURE.I ORDERED A NEW DC MOTHERBOARD, NEW DCHDMI RIBBONS, ETC. AND I COULD NOT GET ANYTHING TO DISPLAY. I SWITCHED MY SOLDER AND FLUX (MG CHEMICALS PASTE) AND THE DCHMI CAME UP NO PROBLEM. JUST TO MAKE SURE I WASNT MAD, I TRIED TO SOLDER ANOTHER DCHDMI RIBBON CABLE ON A COMPLETELY DIFFERENT DC MOTHERBOARD AND AGAIN, IT TURNED ON FIRST TIME WITH NO REWORKING.BOTTOM LINE: THIS FLUX BECOMES CONDUCTIVE FROM HEATING OR IS CONDUCTIVE FROM THE START. ITS ALSO NOT EASY TO CLEAN WITHOUT DOUSING YOUR BOARD IN DI WATER!!!!DO NOT USE THIS FLUX FOR SMD/Circuits/PCB soldering. THIS FLUX BECOMES CONDUCTIVE AND DOES NOT CLEAN AWAY EASILLY IF IT GETS UNDER an IC/COMPONENT THATS SOLDERED DOWN.I'm sure this flux is great for other purposes, but*****REPEAT***** DO NOT USE THIS FOR SMD/PCB SOLDERING.Thank you.Original review:This is hands down the best flux I've ever used for PCB soldering. I'm not joking. Its noticeably better. Just a dab on the IC pins and they suck up solder so easily.Another thing i've noticed is that this flux allows solder to bond with metal at lower temperatures (265 degrees) compared to other activated flux brands I've used.Downside is that when you heat it, it leaves a black residue that's easily wiped away with alcohol or chem wipes.

I rarely write reviews but i was so happy about this product i had to, I didn't know whether or not this flux* would work for electrical wires but i tried it anyways, it has no odor at all when you apply heat( at room temp it kinda smells like a mint chap stick(but dont use it on your lips!), it seems to be non-toxic like the packaging says it is, its extremely cheap compared to other brands i seen on amazon, i definitely will buy this again after i run out, which isn't going to be for a long time since it comes with so much! It's such a relief finding a solder than doesn't make you feel like you're getting toxic fumes pumped in your face. SO HAPPY! ( the photos are from start to finish of how it beads on to the wire)

As can be seen in the pic, the container might not come completely full (or maybe that's just my pessimism speaking). Still, the paste did make a great combo with the soldering wick I was using. I got the 2 oz. container, and at first glance, it does not seem like much; More so, when there's a chunk of paste missing. However, I realized during my small project that a little bit went a long way. I'm using the paste, along with a few other soldering materials, on some small PCBs. The paste seems good so far. Also, according to the labeling it should be Lead-Free, water-soluble, Non-Toxic, and Non-Acidic.

The amount compared to cost makes this a great deal cant beat this

Was larger than i thought. Good value for the price. Awsome product.

muy buen producto.

Awesome value and better than the stuff home depot sells. Using it for plumbing.

Fast shipping item as describe very satisfied highly recomended seller
