How can I get my hands on leaded solder in Germany? Reichelt stopped to sell it years ago and I forgot to order a lifetime supply. Is it available from Aliexpress somehow?

[@PCBWay]

Yes. You can find some on Aliexpress.

👍👌🙏💯💯💯

Take good lead-free-SAC solder and together with a somehow acceptable iron the joints get as perfect as they can be. Cheap SN99 solder with bad flux can really be painful, but beside that all that whining about lead-free can only come from people who intentionally want to be poisonous.

Thanks for sharing!

Definitely with lead. I absolutely hate the lead free one 😅. The PCB's become a mess if you ever have to do repairs and many times you end up damaging good components.

yeah this explains my struggle with getting them to fill the via's pain in the ass.

this is so hard to listen it becomes disruptive might as well say it in chinese so we can pay attention to the subtitles
