Surge in High – Performance PCB Copper Foil Prices
High-performance PCB Copper Foil, mainly HVLP (High-Voltage Low Profile) and RTF (Reverse Treat), is core for AI servers and 5G base stations. HVLP requires ≤0.6μm surface roughness to reduce signal loss, relying on advanced processes like silane coupling coating. However, domestic enterprises face obvious bottlenecks in production expansion. They mostly rely on imported cathode rollers, … Continued
