| Do you still use leaded solder? I was today refused to buy it ... |

I like how they use a ladle to plumb the wire (*no tin here AFAIK*). The lead is sculpted like clay by hand in its semi molten state. many are left in service today. If I could shrink myself down like ant man I would do all soldering this way. Pour lead into a VIA from a 'cement mixer' ^-^ |

What are you working on that requires lead-based solder? --- End quote --- I work on lots of older equipment that was made using lead based solder. I also have never been happy with the performance of lead free when doing hobby projects, it just makes nicer joints, and the amount of lead I will use in my lifetime is negligible anyway so it's not an issue. |

I don't use a lot of solder, but I usually keep a few different thicknesses on hand for hobbyist purposes. There are so many different formulations available with varying ratios of lead and other metals such as copper, tin, silver etc... I don't have a specific requirement for anything exotic, should I just stick with the standard 60/40 Sn/Pb stuff with a rosin core? --- End quote --- Go for Kester 63/37. The 3% make a difference that makes hand soldering just nicer: the lack of a plastic phase makes joints less susceptible to disturbance. I recommend Kester 44 without reservation. Digi-Key sells it in various diameters, of which 0.032” (around 0.8mm) is my favorite. (As well as versions with other fluxes which I haven’t tried.) FWIW, I’ve not been enamored by the Stannol 60/40 we use at work. It’s not bad, but the Kester is better. Stannol’s 62/36/2 is nice. Their lead-free solders work well, but I find their fluxes spit more than I like. I’ve also used Tamura-Elsold 62/36/2 and it’s great, but I don’t know of anyone that sells it. |

Personally, i have been using 1mm STANNOL Sn60PB40 as my daily driver for 30 years, and it is great stuff IMHO. --- End quote --- You should try a good 63/37 solder like the Kester I mentioned. It’ll be quite a treat! |

No such solder-paste anymore? --- End quote --- --- Quote from: Miyuki on November 18, 2021, 06:00:05 am ---Sn62/Pb36/Ag2 is nice but looks like phased out as a wire. Paste and wire are still common. --- End quote --- Haven’t you guys ever looked at Digi-Key, Mouser, or Farnell? You’d know that both of those products are still readily available. |
