I sit on material review boards for my corporation.
For an engineer, those meetings used to be a perfect time to check your personal mail, because there was nothing for us to do, with a very occasional request to find a replacement for something simple, like an electrolytic cap.
Not anymore. In the last couple of months, sh!t has really hit the fan. We are having daily meetings nowadays, and the situation for many components is really dire. Problems caused in many instances by distributors, even though they have had blanket orders for years.
But many times it is related to logistics, but in other instances the manufacturers themselves have simply run out of capacity and have no stock anywhere.
Engineers are now swamped with substitute component evaluations.
The purchasing director, which has over 30 years experience, mentioned that she has never seen such a wide, across the board component shortage.
