SainSmart0.6mm Solder Wire 63/37 Tin/Lead Sn63Pb37 with Flux Rosin Core for Electrical Soldering (100g /0.22lbs)

This is the best solder I have used for surface mount. A little dab of flux and my Weller set at 625-650 degress and it flows smoothly. Remember a little goes a long way with surface mount components and dont forget to use a good quality flux. I bought solder of Ebay and it was crap.JeffKd4lyh

It's great soldering wire for the price , a diamond in the rough as far as cheaper soldering wire goes.Solders easily and neatly, doesn't clump up like other cheaper soldering wire does.

Large pad, small pad, high heat, low heat, tinning, or whatever I'm doing, this solder flows well and leaves a great connection. I solder small FPV (drones) circuit boards often so good solder makes things easy, but bad solder makes things miserable. I haven't had a bad solder yet with this spool. Full disclosure, I also use a SainSmart soldering workstation set which holds everything securely. So my hands are free with this solder in my left hand, the solder gun in my right pre-tinned with a tiny bit of solder on the lower side, and rub around 350-400 C. The board and wire are securely held with zero movement.Iron's tip touches pad for 1/2 sec, solder from spool touches pad, flows right on, pull both back right away, and wait for cooling before moving anything else. Perfect every time.

Doesn't seem to ever have quite enough flux to get the job done. It's a good diameter for most electronics work, I just have trouble getting it to bond sometimes without adding flux.

Me agrado el producto de muy buena calidad, lo recomiendo 100%

I am using this for electronics repair. First use left me impressed with the good quality of this The melting point is good, the flow is good and the adherence is good. I have not done any mechanical testing on joints but I expect it is fine.I used it to repair a broken game cartridge last night and it worked. This solder did not seem to melt or flow at a noticeably different rate from what Nintendo originally used.

Flows perfectly and leaves nice, shiny joints.

High quality tin/lead software. I am building devices that need to function for many years. Lead free solder has the problem of growing tin whiskers that will short out and cause failures. This solder prevents this and is high quality.

Fine solder.

It's solder. It works.

Works great. the wire is a bit thin but maybe that is a good thing. my solder jobs have started looking better lately.

No issues with this solder we got for a science project. Melted easily and was very fine to allow use to be accurate in our solder.

This stuff flows easy and is great for almost anything.
