During the process, I managed to cause som slight mechanical damage to the edge of the chip. When reviewing this under the microscope, I noticed there are multiple small traces going from multiple pads all the way to the edge of the chip. I've damaged some of these traces.</P><P>My question is, what are these traces? What is their purpose? Does it matter if they are slightly damaged? They don't really seem to go anywhere....</P><P>Thanks in advance.</P> Thu, 29 Apr 2021 10:49:19 GMT https://community.nxp.com/t5/MPC5xxx/MPC5554-Edge-Traces/m-p/1270283#M18143 SimcoMH 2021-04-29T10:49:19Z https://community.nxp.com/t5/MPC5xxx/MPC5554-Edge-Traces/m-p/1270809#M18147 <P>That's interesting question.</P> <P>It guess it goes to the test terminals during MCU manufacturing that are removed at the end of the process.</P> <P>I don't expect a slight damage as you shown on the picture would affect the MCU if there is no other damage there.</P> Fri, 30 Apr 2021 10:47:53 GMT https://community.nxp.com/t5/MPC5xxx/MPC5554-Edge-Traces/m-p/1270809#M18147 davidtosenovjan 2021-04-30T10:47:53Z https://community.nxp.com/t5/MPC5xxx/MPC5554-Edge-Traces/m-p/1270817#M18150 <P>That sounds plausible.</P><P>Thank you!</P> Fri, 30 Apr 2021 11:15:37 GMT https://community.nxp.com/t5/MPC5xxx/MPC5554-Edge-Traces/m-p/1270817#M18150 SimcoMH 2021-04-30T11:15:37Z
