Look for a string starting with the brand name followed by a series of numbers (e.g., M3-XXXX ).
Look for "scorched" components near the 94V-0 marking, as APCB boards often house power delivery circuits in that area. B. Mounting the Board apcb m3 94v0 schematic install
Use a multimeter in continuity mode to ensure the DC-in jack isn't shorted to ground. Look for a string starting with the brand
When you see on your APCB board, it indicates that the plastic substrate of the PCB is self-extinguishing within 10 seconds during a fire test.
