    Hello!

    I have in my office some of these 250g solder rolls that are excess parts stock:

    they are STANNOL HS10 S-Pb70Sn30 rolls, anyone knows if they contain lead? Can I use this solder when modding old hardware that has for sure leaded solder? (ie, old consoles and computers)

    I have googled the specs and all I could find is that it is :

    If anyone has any info on this please tell me, thanks in advance! :encouragement:

    Pb and Sn are elements.

    Lead and Tin respectively.

    So yes, its lead.

    And I only use leaded solder.

    Who cares? It's free solder! ;)

    Yeah, leaded solder is much better... but you COULD use lead free if you wanted to. I only use leaded, personally - the new stuff is absolute wank!

    Well I just tried it... it handles like it needs a 40+W iron... tried with my 25W iron and it takes too much time to melt and had to heat the surfaces LOT in order not to have cold joints (just soldered some cables nothing delicate). I don't like it :) this solder wire seems it was made for bigger stuff like the needs of an electrician , not for pcb stuff...

    Can anyone recommend me a solder wire to buy from eBay? preferably within EU? TIA :)

    Liberal application of flux will solve this problem.

    It's normal solder, no high melting point. Look at their website (even though the ratio isn't the same any more).

    Well it doesn't feel like "normal" solder (meaning like the ones I have used), you can't even melt it easily with the iron tip. I don't like it , it's not the same as the other I have here and I am running out of them....

    Pb70Sn30 is not what you want for electronics. According to Wikipedia it is "crude solder for construction plumbing works, flame-melted, good for machine and torch soldering". You should get something like Sn60Pb40. I use Stannol Sn60Pb39Cu1 0.50mm and it is great stuff.
