Sn42/Bi58 T4 Lead Free Solder Paste No Clean, 138℃ Melting Point (20g)

It works well and the applicator is really handy for small spots.

Easy to work with when soldering SMD components to PCB boards. Dispenser allows you to control the flow of paste without creating a mess.

Worked as expected.

It works. However, it flows all over adjacent contacts shorting them together. At this tiny scale, I don't know how this result is to be avoided. I used a minuscule amount and it turned out to be far too much. Also, unlike what some others have said, I had no difficulty squeezing it out of its syringe. The product itself is good, but using it correctly and getting the desired result requires practice and skill.

Easy to use and makes a strong low resistance connection.

Really nice for small electronics you can just inject the Flux sodier mixture. I've used it on bigger wires and it works great too I just squirted on the wires that I've twisted together with my hot air gun and it's as good as one wire

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.

I tested this product as soon as I received. I can tell is really good quality and price is OK. Product was delivered on time and in excellent conditions.
