Context Before

The glass fiber cloth upgrade aims to reduce the dielectric constant of CCL.

Evidence

Beside glass fiber cloth, resin is also a key factor contributing to dielectric constant.

Context After

To achieve a desirable dielectric constant, the CCL makers have their unique recipes to their formulation of the two dielectric materials in the CCL. Currently, debate around the CCL spec is around the adoption of Quartz cloth (Q glass).

② Atomic Claim

除了 glass fiber cloth 之外，resin 也是影響 dielectric constant 的重要因素。
