Kester Solder24-6337-8807 Kester Solder Solder Wire, 63/37 Sn/Pb, 183°C, 1 lb.

If youre working with leaded solder, this is the standard. Been using it for year (decades..??). Easy to recommend.

This is an identical brand and part number that I can get at DigiKey for twice the price. Well worth it just to buy here. This is leaded so you run it colder than lead-less, 650 degrees, which works way better on thin tip Weller guns IMHO without the tip getting so hot it stopping wicking. There is enough tinning in the solder itself you dont have to pre-tin pen your PCBs. The solder is also thin, which makes fine work possible. I would work on a microprocessor and any little 1mm x 2mm resistors with no problem with this solder. This is a quality name brand at a good price.

Product was on time and as described.

This is far and away the cheapest retail for this product. I needed quality no-clean solder fast, and Amazon delivered. Im accustomed to using 2% or 3% flux, so I did have to turn the temperature up a bit on my iron, but it flows very smoothly. I am very pleased with my projects so far. Yes, there is a bit of cleaning afterward, certainly nothing like cleaning rosin flux for hours.

You always get quality with Kester but this particular blend flows as smooth as silk when working on smaller electronics projects. Like butta Most people never know the difference a quality solder can make until they use a product like this side-by-side with the brand-x cheap stuff from the dollar store. its only then that people have that ahh haaa moment and then probably go back home and do the same thing with all the other junk that the thought didnt matter like chucking the one-temp plug in style soldering iron for a Weller or a Hakko and basically just understanding that you cant produce quality work with poor quality tools and materials.

Melts like butter at around 200 C and wets like water. Amazing solder and with a hefty 1 pound spool, its gonna last for ages if you solder infrequently.

VERY fine-gauge precision 63/37 solder for electronic work or re-work. Usable for anything, but where this stuff shines is when youre replacing blown components on a PCB and cant be sure you can get all the flux off the board when youre done (you should still try with Isopropyl alcohol anyway) and not having a corroded mess a few years later matters. For larger soldering jobs youre going to feed a lot of this stuff, but thats ok. Its a nice-sized spool and will last you a long time; Kester makes some of the best and Ive been using it for more than 30 years. If you dont do fine PC work or rework the larger-diameter solder is more-convenient, but for high-precision work this is the jazz.

The best, hands down

Great Solder. Kester is a great brand. Very clean and low fumes. Great for general electronics.

I can work with this at 250 Celsius and it works amazing on both SMD and Thru-Hole packages. The finish is very shiny and the eutectic nature of the alloy gives very clean finishes. The 1.1% flux is alright but using additional flux is very helpful because the flux in the solder evaporates quickly. Note for SMD soldering, 0603 packages is the smallest you should be soldering with this (mainly what I solder), its doable but even then you need to be careful to not apply too much. For smaller packages it is too big, for thru-holes its perfect. Overall brilliant product, absolute must have for hobbyists.
