A good engineer makes every stuff work,
even defective chips?

would you be inclined to deal with a company that told your boss you were incompetent?

When the first Arghmel '51s came out (1995) I found a defect in the chip. I told Arghmel, and told mmy boss we needed another brand. My boss approached Arghmel to return the chips and was told that they could not accept returns based on findings of an incompetent person. I lost my job, because I could not make this faultless (they believed Arghmel) chip work, and, lo and behold, a few revisions later the error I reported appeared in the Arghmel Errata for the chip.

I have no problem dealing with a company where some early revision of a chip has a defect as long as they are willing to admit it and fix it in a later revision. This is "the name of the game". Just look at the I²C issues in the ST32 10x'es fully documented in the errata. This has not kept me away from ST.
