Features
The company has developed fine-grain and high-strength copper foil of low surface roughness and high-temperature ductibility performance. This foil features evenly fine grains and high extensibility and can prevent fissures caused by thermal stress, thus suitable for the internal and external layers of a multilayered board. With a low level of surface roughness and excellent etchability, it is applicable for high density and thinness. With excellent tensile strength, it helps to improve flexibility and is mainly applied in the multilayer PCB as well as the flex plate. With excellent resilience and toughness, it is not easily torn on the edge or fold, greatly improving the product conformance rate.
● The treated foil in grey or red
● High peel strength
● Good etchability
● Excellent corrosion resistance
● Anti foil cracking by high elongation at elevated temperature
● High elongation after treated with high temperature or annealing .
● High THE property.
● Effective in the prevention of cracking plate.
Application
● Polyimide board
● Epoxy board
● CEM-3, FR-4, FR-5, Hydrocarbon substrate
● Multilayer board
● High Tg, lead-free and halogen-free, Middle Tg
● Positive temperature coefficient resistance
