ROHS compliant 63/37 leaded solder paste?

<< < (4/6) > >>

eKretz:
Gotta be counterfeit. It's highly unlikely that a company like MG Chemicals would make a mistake like that.

Ian.M:
Take a look around the MG site at the images for their solders and pastes, and you'll see the inconsistencies with their house 'style'
Lets see how they could get there:

Start from a Pb free packet insert card
1. Type 'SN' instead of 'Sn' and 'PB' instead of 'Pb'
2. Paste in "SN63/PB37" five times
3. Edit "LEAD FREE" to "LEADED"
4. Forget to edit the other languages
5. Add red stripe for Sn63/Pb37

or:

Start from a Sn/Pb product card.
1. Use wrong graphic
2. Upper case all the 'Sn63/Pb37'
3. Change all non-English text to equivalent Lead Free text.

Neither of those scenarios are plausible at the real MG even if the card was updated by an unpaid school age intern, as someone more senior would have had to check and approve the artwork before it went to the printers. 

I'd say there's a 99.9% chance its pure fake, and a very small chance someone dodgy is breaking down condemned date expired bulk packs and repacking in fake retail packs.

Tomorokoshi:
Additionally, there is strange capitalization in "BLEIfrEI" in the German section.

helius:
In addition to the issues identified by Ian.M, I will note that none of the products I have ever bought from M.G. Chemicals have languages other than English, French, or Spanish on the label. And they do not have the "e" sign, which is defined by the EU.

The person(s) who counterfeited the insert card have added the "e" sign and multiple languages to maximize their sales to countries they have identified as potential markets. Note how on the left side there are six times repeated "Superior joint strength", but only English and French translations of this phrase were available: the counterfeiters could not find translations into the languages which they added to the label (Spanish, Italian, German, and Korean) so they left the rest in English.

smbaker:
I've sent an email to MG Chemicals technical support and USA West sales with a copy of the packaging and the lot number of the paste. Hopefully they will get to the bottom of whether or not it's legitimate product. You'd think they would want to know if counterfeit or expired product is being sold at a major retailer like Amazon.

Comparing the paste I received to pictures of the paste on digikey and mouser, the syringe itself looks identical, though the needle shown in the pictures is different. That might not be significant, it could be they switched needle suppliers since digikey and mouser received their artwork. The label on the syringe itself appears legitimate (no language oddities), although a piece of scotch tape has been attixed to the seam of the label, perhaps to keep it from pealing off.

It's also the case that this was shipped without cold pack, though the lack of a cold pack may be a casualty of buying from a generic retailer like Amazon. I have to wonder how long it sat on the shelf, potentially unrefrigerated, before I received it.

I'm betting on Ian M.'s suspicion that this is expired bulk product that someone is repackaging and selling as individual new retail.
