Chips pulled off dumped PCBs and then sold, due to the "chip shortage"?

<< < (4/6) > >>

Faringdon:
Thanks,
I also believe that at component vendors, when someone drops a $5 chip  or it  accidentally gets handled without ESD precautions...they then put those chips in the "do not sell to bona fide companys" box...and those chips only get sold to hobbyists like myself...who arent from a "genuine" company.... do you also concur with this?

No I don't concur.

The UK reputable distributors dump them in a white expanded polystyrene box labelled 'treez' and wait for you to order something. All the rest of us get genuine, properly handled parts.

The China Ali, ebay etc. sellers can't pronounce 'treez' [Edit: or 'Faringdon'], so send you the same fake / salvaged crap that they would have sent to the rest of us if we had taken that path.

I'm just waiting for the inevitable fresh thread: My flaky design keeps blowing up and I don't know why so it must be dodgy components...  :popcorn:

Really, he is still around here? But with a different nick? I was finding strange not seeing his stuff but since I've been out for some months it was expected. But now this?

Due to the chip shortage, are  there places where old scrap PCBs are haveing chips de-soldered from them, and then the chips cleaned up, and then sold on as new?

    Not necessarily "As New" but it's a common practice in electronics repair industry and has been for a very long time. It's the only way that repair companies can get some obsolete IC and other devices (aka "chips"). One of my friends owns a company that does this and he's been doing it for as long as I've know him, over 25 years at this point.  They routinely pull socketed chips (sold as "socket pulls") and depending on the demand and the value, they might even unsolder chips (sold as "solder pulls").

   I recently bought four LM399s from him and they were used but worked perfectly.
