SP-7 Silver Solder Paste 7.1 Grams | Soldering Flux Paste for Electronic Components, Home Improvement, and Wiring | Silver Solder for Jewelry Making and Repair | Lead-Free Solder Flux

Works great. Fixed my jeep wrangler defrost button with this.

A++++Excellent product.Of course, good soldering skills will help.I am a very seasoned and capable electronics tech and this product nails it.I used it, also, to resolder a broken spit valve on my bass trombone. Worked perfectly.One note - the paste is fairly thick - so, once it starts coming out of the tube, back off the plunger so it doesn't continue flowing.

We have used this solder before never had any problems with it.But this time is a different story.This is supposed to be low melting solder and the first two times we used it. It was but not this time. I was using it last night and could not get it to melt not even with the torch.It seemed to form a layer of something at the top and refused to melt.So I’m wondering if we got a bad batch or if something else had changed in it.It’s up in the air weather we will buy it again or not.

Disappointed. Once it fully melted there was barely any solder. As others have mentioned the tube is full of mostly air.

I used it to repair sterling silver earrings by attaching new sterling ear wires. Works great and was easy to use! There's not a lot in the tube but really you don't need a lot and it saved me the expense of taking it to the jewelers.

This melts fast. I used a butane torch to heat my piece and when I used a pick to place the paste it melted immediately, smoked and actually sparked and burned a hole in my sleeve. This is super-duper easy solder that melts way before other solders I have used for jewelry making. Once I was done with the solder joint I picked up the piece and I came apart. I redid the soldering again and let it sit for 15-20 seconds and this time it stuck. My thermal gun measured the temperature at 590F immediately after the soldering and it was in the lo 300s when I picked up the piece for quenching. I place the piece in pickling and when it was done I started finishing the piece. Just my handling made the joint break - this is after pre-cleaning and using a scotch pad wheel on a Dremel tool to make sure it was ready for work. As an experienced soldering professional I find this to be too delicate for my needs. This solder paste is likely meant to be used with alloys containing zinc. When it says you can use a lighter to melt this paste, it is not hyperbole, it’s true.

Good stuff, worx as advertised

makes soldering so much easier..you do not need to use much for good connections
