Apcb M3 94v-0 Schematic File

Look for markings on the existing PCB:

| Feature Element | Purpose | |----------------|---------| | Net class table | Label nets as VCC_5V_94V0, GND_94V0, HV_94V0 | | Spacing notes | Example: “Between HV and LV nets: min 1.5mm for 94V-0” | | Solder mask callout | “Solder mask over bare copper (SMOBC) required for 94V-0” | | Manufacturer P/N | APCB part number for 94V-0 laminate (e.g., APCB-EM-370) | | UL marking | Symbol on silkscreen: 94V-0 + APCB logo |
