STM32L151RET6 chips faulty/bad/fake ?

<< < (4/4)

tom66:
Both chips show a few signs that they have been removed from PCBs, something I didn't really notice too much the first time I looked.

For the right hand chip from older board this might be expected (maybe desoldered to inspect?), for the left hand chip did it come off the tape like this?  Or is that also removed? 

Leads bent, and a glossy look to the leads in places that looks like it could be excess solder.  Hard to say for sure but I would certainly expect excellent coplanarity for a brand new chip.    Worth checking a few parts for signs, also look for dirt/flux stains/IPA on the chips.
