Sn63/Pb37 T4 Tin Lead Solder Paste No Clean, 183℃ Melting Point (20g)

Good stuff

I love this liquid solder. I used my new heat gun with this product and it was an excellent experience. Would highly recommend, of course you will also need a heat gun. Was able to fix the circuit board on my key fob.

Es buena, a veces siento como que le costara adherirse al metal pero es cuestión de calentar un poquito el metal

Good flux, but not a "no clean" flux. It makes all my hotair rework components flow and wet really well, so the flux works well. I was hoping for easier cleanup with 99% IPA.

The product came in a nice colored pouch with 2 narrow metal heads and two plastic nozzles. It's a decent resealable bag so the solder pen and heads go back in the bag to keep everything organized in my office.The metal tips are great when applying the solder paste while holding the rework gun without worry the tip will melt and the plastic tips are great for precise positioning of the solder on the boards you're working on.I started removing Mics from PCB boards and charging ports and my job was quite hard not having something that had a lower melting temp which is what I needed. Using regular solder and heat caused my components to be toasted after all the heat and the ports melted by the time I got the solder to melt.While with this new solder paste pen I can actually apply solder without the worry that my components will be destroyed while melting back the new parts.Overall I'm happy I got to experience what it's like to use a solder paste with a lower melting point that standard lead solder. Though they do make such a solder paste with even a lower melting point at 138 deg.Overall there's nothing I would ask for more. And I'm very happy happy with everything about the product. Will try to attach some pictures from the next job I do.

I used this product for soldering solar cells together. It worked well (melting point is above other solder I’ve tried), but halfway through connecting a string of cells, the consistency of the paste became much more liquid. This ultimately resulted in failed contacts and a major headache.If you use this soldering paste, keep an eye on how thick it is.

The paste doesn't stick to the pads (gold plated).I had to use a tooth-pick to push and smear the paste on the pads.My surface mount parts would fly off before the solder paste would melt. I changed the settings but cannot get it to stop. Using 0603 size. The solder doesn't evenly distribute like the videos show. I end up with a large solder ball on one end and almost nothing on the other. My parts appear to be floating which means there are little solder balls under neither them. This is electrical and mechanically a nightmare.I tried to just smear the paste on the pads with a tooth pick and not component. Then melt the past onto the pads. Then reheat and the component so the component will suck down. Some pads came out okay, others, if you don't get the amount just right, then there is a giant solder ball.Environmentally, this stuff is a nightmare as small led solder balls will form and then get blown away with the heat tool. Not to mention what does melt and ends up on the tooth pick or other tools I've use that I cannot throw away. Now my lab has tiny lead balls that I will need to hunt down so I don't have a toxic mess.

Works good
