No-Clean Soldering Flux Paste, flux for Soldering, Electronics Solder Paste Flux for PCB/IC/BGA/SMD/SMT/LED Repairing (10mL Syringe) #9530 (1 Pack)

This is a good product for soldering, works great!

very clean soldering

Got this stuff to do an hdmi connector replacement on my friends Xbox. It works much better than the stuff I was able to find locally. And coming in a syringe for easy application is pretty convenient. Melts clear and is easy to work with.

This flux works very well, and it's nice to not have to worry about removing every last bit. The only problem I had with it is that the dispenser nozzle seems to be a little too thin for the viscosity of the flux. A gentle press on the plunger results in a bunch of flux spraying out instead of a little bit flowing in a controllable drop. I ended up squirting some into a small plastic cup, and then using toothpicks and small touch-up brushes to apply it.

Excellent flux but the dispenser gets an F for difficult to control and drips all over the place.

I recently picked up this soldering flux paste, and I have to say, it’s really handy to have around.The consistency is just right. It’s not too thick and not too runny, so it’s easy to apply exactly where you need it. It really helps the solder flow smoothly, even on those tricky joints. I’ve noticed a significant improvement in the cleanliness of my soldered connections too, with minimal oxidation or residue.What’s nice is that it doesn’t smoke excessively when heated, which is a relief because I’ve dealt with some pastes that smell awful or make it hard to see what you’re doing. Clean-up is also simple. A quick wipe with some isopropyl alcohol, and it’s like it was never there.Overall, it’s affordable and does its job well, especially for small electronics work. Definitely worth having around if you do a lot of soldering.

Alright -- let's get something out of the way. You should always clean your PCBs. Whether or not you use no-clean flux, there are plenty of other contaminants on a board that can affect performance if you don't deal with them. From debris left over from PCB fabrication to cheetos dust from your fingers. Take some high proof isopropyl alcohol, put it and your board in an antistatic bag, squeeze the air out, and then drop it in a warm ultrasonic bath for a while and do a distilled water rinse and let dry! (Warning, don't do that if you've got parts that can't be washed -- like humidity and barometric sensors, mems microphones, etc. -- check your datasheets).And for all you haters out there who don't like my cleaning idea -- then by all means, go to Aqueous Tech and get a professional cleaner.

If you want something mediocre go ahead and purchase this, it is messy, sticky and doesn’t flow as well as other higher quality fluxes out there. I can’t say I’d recommend it at all.
