Sn42/Bi58 T4 Lead Free Solder Paste No Clean, 138℃ Melting Point (30g)

Easy to use, I don't have a hot plate just a heat gun/ hot works station and it worked great. Had very little clean up with a small TSOP chip.

Works as advertised, A bit hard to push out but It’s not their fault.

Honestly thought I was getting a lot more flux than this, guess Im used to the stuff that comes in small round tin. I bought the 20g size, the photos are of the tube unused, took them right after opening the package. Its my first time buying/using this low melt stuff, that probably explains the amount per price difference. Which Im cool with, I can imagine the amount of R&D for this stuff.. I needed to solder but with minimal heat and this stuff sure did the job quite well actually, so its definitely worth the price. Will definitely get more when I run out.

This does work well as is. However, it work smuch better if you brush on a little flux and lower the heat. Then it is perfect!

Easy to use. Clean design. And it has a few different tips to swap out as needed.

First it's very hard to get it using syringe. It's too hard, it just want get out. So, I need to apply two hands to get a bit of it. Second problem is that doesn't stick very well to the copper. So I need to use a toothpick to help it. The strugle doesn't end here, once it gets heated up with hot-air-gun it becomes too liquid and spreads way to much. Sometimes I have to resolder every thing since the paste goes underneth the components (SMDs) and short circuit. The problem feelt especialy on 0.5mm pitched SMDs. Sometimes it's handy but I would not recomend to a friend.

Terrific !

This was the first solder paste I ever tried to use. It was pretty simple to setup the "syringe", and while an ultimate test might be how well it works after some time has passed, this was a pretty good deal. It will still take skill to dispense this, IMHO, regardless of what brand you use. That takes practice. Just watch how much is coming out, and realize that for a tiny pad like you get for surface mount components, you really don't need much.I wound up using something like 380 degrees for my heat setting, on an inexpensive Yihua(r) rework station, and very low fan setting, just as an aside.

Simple to apply this SMD solder paste. It's fast and simply great.

Made soldiering very simple and easy, would recommend.

Help to avoid soldering bridge. Good

very well put out kit, I put some on my broken chip solder points to swap it for a functioning chip. Heat gun and voilaaa

Used this with a reflow hot plate to solder tiny WSON-8 package without using paste mask. Worked ok for me.
