| ROHS compliant 63/37 leaded solder paste? |

The Reduction Of Hazardous Substances is specific to electrical and electronics products. Since a tube of solder isn't electronics, I suppose it complies with the regulation. There is also a confusing concept called "ROHS-5", which means that the product is free of mercury, cadmium, chromate+6 ion, and brominated phenyl ethers, but does contain lead. This is used to show that the manufacturer does care about pollution, but that they use lead for reliability reasons and the user must be exempt from the regulations (military, medical, or network infrastructure). |

Look at the photograph of the whole package, and the product description in big bold letters at the top. The English product description says "leaded" (as one would expect from the Pb37 spec). But all the other languages right underneath seem to state "lead free"?! ??? |

I have the same paste, both in syringe and a 250g tub, and neither has that logo anywhere on the packaging or the syringe. They work extremely well at room temperature, or even straight out of the fridge, so I suspect you don't have the genuine article. |
| TimFox:
Note that the chemical definition is 63% Sn (tin) and 37% Pb (lead), but that the various languages under that all say "without lead". Alternative facts? |

What eblaster and TimFox said. It is quite fishy that you see Sn63/Pb37 right above "unleaded" in four different languages. If that's a renown brand, I would say this a counterfeit. |
