Context Before
The classification of CCL materials is determined by its dielectric constant (Dk) and dissipation factor (Df) at a given frequency. Insertion loss is lower at lower Dk and Df value.
Evidence
The common classification is anchored to the Megtron series from Panasonic as they have been setting the industry standard.
Context After
When people describe the CCL as M7 classification it usually means it matches the same Dk and Df specifications as Megtron 7 of Panasonic.
② Atomic Claim
業界常見的 classification 以 Panasonic 的 Megtron series 為基準，因為該系列一直在設定 industry standard。
