The MV-4 94V-0 is a classification of printed circuit boards (PCBs) that meet specific safety standards for electrical devices. The "MV-4" refers to the board's material, construction, and performance characteristics, while "94V-0" is a flammability rating assigned by Underwriters Laboratories (UL). In this paper, we will explore the requirements and implications of designing and manufacturing PCBs that meet the MV-4 94V-0 standard.
94V-0 material (FR-4) has ~175–250. For >30V: maintain creepage distances (1.5 mm+ depending on pollution degree). Schematic notes : Add “Creepage: X mm” near high-voltage nets. mv-4 94v-0 schematics
- PCB: FR-4, UL 94V-0 - 4 layers (MV-4 stack-up) - Copper weight: 1 oz outer / 0.5 oz inner - Solder mask: both sides - Silkscreen: white, lead-free compatible The MV-4 94V-0 is a classification of printed
Here are some notable features:
