(25ml) - MG Chemicals 4900P SAC305, Lead Free Solder Paste, No Clean, 25 g (25ml) Pneumatic Dispenser (Complete with Plunger & Dispensing Tip)

I was scared to do lead-free reflows until I got this solderpaste. Seems like this was a little better quality than ChipQuick. Maybe it's because the stuff is newer, but I would argue it flows better for some reason.

Buen producto y no contamina con plomo el ambiente.

Dommage que le produit soit un peu cher, et que le pâte au début du tube soit un peu dure.

Buon prodotto

This is fairly good solder mixed with a lot of flux.I must say that "no clean" is a little optimistic given the large amounts of flux. The flux cannot be cleaned off with water so you may wish to buy a suitable cleaner / flux remover. Otherwise, it does the job well.You need very little of the paste to make a sound joint on SMD devices. Accordingly the syringe full will last quite some time for hobby use. On that, I would say that I bought this at the end of January and now, eight weeks later, it is still perfectly usable despite never seeing the inside of a refrigerator. Kept in an coolish room (20 degrees), it has lasted well. Whether that would also apply during a hot summer is another question. However, if you are able to refrigerate it and extend its life I suggest you do so.Overall, good value even if you do end up throwing half of it away. If you're soldering SMD components, you really do need paste rather than wire solder, so the options are limited.
