PCB industry's 'M8'/'M9' terms originate from Panasonic's Megtron CCL series

By PulseAugur Editorial · [1 sources] ·

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.

    Ever wonder why PCB folks throw around "M8" or "M9" like a spec sheet magic word? The "M" traces back to Panasonic's Megtron series — long the benchmark for low-loss, high-speed copper clad laminate (CCL). Each generation from Megtron 4 to 8 progressively lowered the https://t.…
