-Definitely it was not DoA :-) Nobody has ever found out what really caused this hole. Well, although it was easy to repair the board because no chips were affected, I could not send it back to the customer at such a condition. Luckily, there was sufficient profit margin for the entire project, so I shipped a new one and kept this one in my "Archive of Terror".
+Definitely it was not DoA :-) Nobody has ever found out what really caused this hole. All ICs were working perfectly. Well, although it was easy to repair the board because the density of the PCB trails at those times was really small, I could not send it back to the customer at such a condition. Luckily, there was sufficient profit margin for the entire project, so I shipped a new one and kept this one in my "Archive of Terror".
