Recently I had a batch of boards assembled by a company and they were found to have counterfeit ics in them and the boards didn't work.
It was up to me to find out why these boards didn't work and to determine that the ics were counterfeit. I was not happy. After much too-ing and fro-ing the board assembler replaced seven ics on each board with hopefully non-counterfeit ics. After getting the boards back, I asked for evidence of the source of these ics. It seems they used another non-franchised supplier for these ics (which I thought was rather stupid considering the initial problem) and the supplier didn't want to state their source. After a bit of negotiation the supplier exposed their source and luckily it was a known and franchised distrbutor. The net result was that a lot of my time was wasted solving a problem that shouldn't have happened. Who is liable in this instance?
My question is: do you think it is important that your board assembler ensures they have a traceable supply of components? What is the usual practice in other countries?
