The terms "M8" and "M9" in the PCB industry are derived from Panasonic's Megtron series of low-loss, high-speed copper clad laminates. These materials, particularly Megtron 4 through 8, have progressively improved signal integrity by reducing the dissipation factor. Consequently, "M8 grade" has become industry shorthand for meeting specific electrical performance standards, regardless of the manufacturer, as demand for high-tier CCL intensifies due to AI server requirements. AI
IMPACT High-tier CCL is becoming a critical bottleneck for AI servers, driving demand for materials that ensure high-speed signal integrity.
RANK_REASON The item explains the origin of industry jargon related to PCB materials, which is commentary on industry practices rather than a direct release or significant event.
