As the next generation mobile communication network, 5G infrastructure construction is expected to significantly boost demand for communication PCBs, including high-value products like backplanes, high-frequency high-speed boards, and multi-layer PCB boards.

While special substrates like polyimides and ceramics handle wider temperature swings, FR-4 laminates have evolved with "high Tg" versions usable to 150°C+ while maintaining lower costs and better fabricator familiarity, making them suitable for many industrial applications.
