Kester 24-6337-0027 Solder Roll, Core Size 66, 63/37 Alloy, 0.031 Diameter

I am not an electrics expert or hobbyist and have been using 60/40 solder which is easier to find. I decided to try the 63/37 based on some recommendations.and it was a very nice improvement. The 63/37 stayed at the solder joint while the 60/40 tended to wick up the wire causing the wire close to the local joint to become more brittle. Use 63/37 for cars, airplanes, boats, motorcycles, etc

Does the job

Have you ever wanted to solder micro PCB transistors and resistors like a demi god/ robot? Then this solder is for you. Do you want a lead solder with a competent flux that will bond your connections like a champ, and give off fumes with the sweet taste of Bismuth salts and antimony that pairs nicely with a glass of Montepulciano or a Sanghiovese? Then this flux core is for you. Do you want to live as long as possible and keep your sperm count up? Then maybe youd prefer a Rohs solder, and after throwing it across the room youll realize: laboratories and electronics are not for you. We all die sometime, were surrounded by death. No need for the constant reminder from our electronic devices that die before their time, due to inferior Rohs compliant solders. Women like mysterious dangerous men, and what could be more dangerous than a man who breathes fire and lead fumes? Nothing. Take it from me: a scientist; put a roll of this bad boy in your laboratory and watch the panties drop. Now I know what youre thinking: we have a disparity in the sciences, with too few women taking degrees in the hard sciences thanks to years of uninformed dogmatic gender role ascribing women to careers other than the hard sciences. Now were paying the price. Do you realize how hard it is to get a lady in your laboratory? Well, true. And no. I dont. because I use spools of lead solder. Fact: women are drawn to the sweet smell of Bismuth salts and the pheromones excreted by a man with acute lead toxicity coursing through his veins are unmistakably unique. It intoxicates their senses, theyre drawn on a genetic level to procreate with you *immediately* because, with lead, there might not be much more time. Pretty sure Darwin mentions the mechanics of this exact biological drive in his work The Expression of the Emotions in Man and Animals but I wouldnt know. Im a real scientist, not a biologist so Ive not the time to read such quackery. What I do know about women Ive learned from observation and captain Kirk. From observation I can assure you, heat up some of this solder, sit back and watch the women come in droves. Your lab will make Hughs house look an all boys academy. Hang another roll from your review mirror. Trust me. This solder will save us from the gender disparity in the sciences. It will save future generations. But, dont wait, copulate. After all, it is lead bearing solder, so theres not much time. I will continue to buy this solder.

Top notch product, perfect for rc hobby soldering.

This is as good as it gets! Way better than any other solder I’ve tried. Don’t let the price deter you, this roll will last the average person a long time and makes soldering much easier, with better results.

Just as advertised. Prompt delivery and quality product.

Great product, but I would not expect otherwise from Kester!!

I bought this rosin core solder after much research. Im glad I did because it works like a charm. Enough solder to probably last me a lifetime!
