The Types segmentation categorises the product based on carrier material and construction methodology. The first type, Copper‑clad laminate (CCL), integrates copper directly onto a polymer or glass‑reinforced substrate, offering high dimensional stability for rigid PCB applications. The second type, Copper foil with polymer carrier, uses a thin, releasable polymer film that facilitates automated handling and precise lamination, essential for high‑throughput FPC production. The third type, Copper foil with glass carrier, employs a glass‑based carrier to provide superior flatness and thermal resistance, targeting aerospace and high‑frequency modules where surface uniformity is critical. Within each type, sub‑categories such as single‑sided versus double‑sided copper, and varying copper thicknesses (e.g., 12 µm, 18 µm) further differentiate market contributions. While the Types dimension does not appear in the chartData, its internal diversification underpins the overall market size by aligning product specifications with the application‑driven demand outlined in the Ultra Thin Copper Foil with Carrier Foil segmentation.
