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 dissipation factor (Df), meaning less signal loss at high frequencies.Because Megtron set the bar, it became industry shorthand for a performance tier rather than a Panasonic-exclusive part number. Say "M8 grade" today, and it simply means "meets Megtron 8 electrical specs" — whether it's made by Panasonic, EMC, or Doosan.As AI servers demand ever-higher SerDes speeds, high-tier CCL has become the critical bottleneck material. That makes it one of the tightest, fastest-growing segments in the entire hardware supply chain.

Major Taiwan CCL manufacturers Elite Material and ITEQ said they will expand capacity amid soaring demand related to AI, with visibility extending to end-2028, media report, adding AI chips, 800G/1.6T network switches, LEO, and cloud infrastructure are all driving demand for the material used in circuit boards. Demand for high-end materials remains in short supply, and EMC noted high end boards used in AI servers have soared past 80-layers, driving demand for high-speed materials. ITEQ will double capacity for high-end products in 2026. CCL: Copper Clad Laminate
