Definition

Kingboard Holdings (Hong Kong) is the world's largest CCL manufacturer, controlling significant global market share. Their product line spans standard FR-4 (KB-6160 at Tg 130-145°C) through high-Tg grades (KB-6164 at Tg 150-155°C). Kingboard materials dominate high-volume Asian production due to competitive pricing and broad availability. While Kingboard focuses primarily on standard and mid-performance grades rather than ultra-low-loss materials, their high-Tg products meet lead-free assembly requirements. Most Asian fabricators stock Kingboard as their default FR-4 supplier. For commodity high-volume production, Kingboard offers the best combination of availability, consistency, and cost.
