247-SNPB-15 No Clean SnPb Leaded Solder Paste 15 Grams Sn63/Pb37 T4 88% Metal

This kit worked great! Come with two nozzles and a orange sealing cap. All the nozzles and cap twist into place on the syringe to form a tight seal. The pink (fine tipped) nozzle was PERFECT for applying a fine line on SOIC or dots of solder paste for diodes/caps. The solder paste wets fast and creates a quality joint. I was using a 350C Weller DC station with a fine tip. Drag soldered the SOICs. Amazingly easy, fast work soldering the items in the photo. I used isopropyl alcohol and a tooth brush to clean up residual paste. A 1mL medical syringe (slip the needle off the end) fits nicely into the pink nozzle for flushing the nozzle with alcohol. Would buy this again, but its going to take me a while to use up 15g of solder paste.

I love this stuff! Maybe I'm just super new to this thing and still hypnotized by how easy solder paste is to use, but I put a tiny bit on some surface mount chips and soldered them with my station, and all I can say is wow! As a novice in smd soldering I found this incredibly easy to get the hang of. I found that I was using more heat than I needed to do the job and over time I found a sweet spot for it. The solder reflows really well too once initially heated, the only drawback I found with the whole setup is the purple precision tip, you have to be a bit careful because it can build up some pressure and keep dispensing paste a little bit even when you pull the plunger back, but with practice it becomes less of an issue. This is the second solder paste tube I've ever had and it's way better than the first one I had which was a silver bearing solder paste.

This is the first solder paste I've ever used. Works great for SMD stuff. There was some air in the tube. Not sure how to prevent that, but it creates a bit of a buffer; when you press the plunger, it compresses the air. And then the solder paste comes out. When you stop pressing the plunger, paste still seeps out a bit. Not sure if that's standard or not. But it's annoying. Wish it had a nice cap. I just put a plastic piece I got from a test lead on the end, and it mostly fits. I put it in the refrigerator when I'm not using it. It did come with two tips. Seems to work Ok with the smaller plastic one. Minus one star for no cap and air issue.

It is a solder paste. Having made hundreds of solder joints using it, I've seen none of the problems that are reported with other solder pastes. It is a mixture of tin/lead balls in a suspension of flux, and the flux also works well. Of SMD paste or flux complaints, it seems common that folks complain about boiling flux making solder balls go everywhere. I have not experienced that problem with this solder paste, whether with my iron or my hot air station. The first tube I had got lost. It worked well enough that I bought it again. And it seems to be current product, which is said to make a difference for such things: I ordered in the middle of September 2019 and got a tube of paste dated in early September 2019.

This was my first experience reflow soldering. Obviously I didn't have an oven, but careful use of a heat gun worked well. The plastic tip supplied with the solder worked well for the 0805 (tiny) components. As I applied heat, I panicked a bit because everything kind of melted and went all over the board, but as it got hot enough for the solder to actually melt, it magically sucked the components into place and left me with beautiful (at least to me - I'm not a solder technician) solder joints. The completed project worked as expected, so the solder did its job that way too. My only (very small) complaint is it's basically impossible to get the tip clean for reuse. Denatured alcohol and an air compressor helped, but didn't get everything...

I prefer this low temp paste solder for soldering replacement dial feet (copper wire) to watch dials. I use a resistance soldering machine and this solder has served me well over other forms of solder. There was a drop in performance past the expiration date, so I recently had to purchase again. There was plenty of solder left in the syringe. Hopefully the remains will be useful for less precise work, such as electronic components and wires.

This allows human hands to effectively work with small, surface mounted electronic components effectively. I was very impressed. It is a tin / lead powder suspended in flux which allows for a precise application of the right amount to the right spot. It also allows for cooler temperatures to be used while still yielding an excellent result.

I bought this solder paste to repair some tiny flat pack on a circuit board. It was some difficult soldering for the tooling I own. This solder was easy to work with and flows as smooth as butter. Excellent produc!!!
