People often confuse FR-4 and 94V-0. stands for "Flame Retardant 4" and is a specific type of glass-reinforced epoxy laminate. 94V-0 is a flammability certification that can be applied to FR-4 materials. In fact, modern FR-4 PCBs are almost universally manufactured to meet the 94V-0 standard. When a board is labeled "94V-0," it confirms that the FR-4 glass-epoxy laminate used meets the highest UL safety standard .

The "CM-4 94V-0" marking is a generic UL flammability rating (94V-0) and a common printed circuit board (PCB) identifier, often associated with components manufactured by (part of the Foxconn or HANNSTAR group) . It is widely found in consumer electronics, including HP , Asus , and Lenovo laptops. Component Identification Report Lenovo CM-4 94V-0 E162264 Motherboard - eBay
