"Mechanic" SnBi solder wire - fake

I got a roll of low-temperature solder wire today.

It clearly has a higher melting temp than my Sn60Pb40.
Avoid.

Umm, from where?

Plan to p&m to the vendor? I definitely would.

Yeah, when I got a coupon from MicroStore for 10bux/20bux/whatever off (use like cash), I went’n‘got two 1lb spools of regular good ol’ fashioned SnPb solder.

I’m set for a long time. Big Smile

I use one that have sticker same design as on mehanics solder paste. Works great. Many years ago I got one from dx.com, nowadays you can find it on ebay.

Need a vlogger for machine accessories reviews

From here:

I intend to start a dispute as soon as I have a video of this being solid at 200 degrees-hot iron tip (even if tip temp is lower than I set it to, at the same time I got a blob of Sn60Pb40 being fluid at the other side of the tip).

I also have Mechanic paste. I haven’t compared it with anything, but it works.

Yep the Mechanics Sn63/Pb37 solder paste works, I prefer Kester EP256 paste, and use Kester SN63PB37 (.031) wire, but my favorite wire is Stannol LoveThumbs Up

BTW, no surprise, there are others noting that it’s fake:

The seller has sent me a test report of a compliance check with EU regulations. This tests show that the solder is lead free and not very contaminated. For this reason my suspicion that the solder is just recycled is much weakened.
Anyway it doesn’t show anything about actual contents.
If anyone is interested in seeing the report, PM me.

BTW, I won the dispute even though the video that I created was of very poor quality and I wouldn’t grant myself a refund after seeing it. Big Smile

If 100% fake, it melts at ~230C, even higher than regular SnCuAg solders.
