Transparent PCB-PET FCCL
Cr-Free Sputtering & Plating Type PET FCCL
PET FCCL, Cu/PET/Cu film is an adhesiveless double-sided (D/S) copper clad laminate, using PET film and sputtering with electroplating Cu Plating on both sides.
Coated PET transparent film, coated PET substrate glue, and cured to form PET-FCCL, which is different from the traditional PI-FCCL substrate in the type of coated substrate.
Cu/PET/Cu films are designed for a wide variety of flexible cables and LED packaging substrates applications which require advanced material performance, temperature resistance, fine pitch, and high reliability.
Product Characteristics
Excellent dimensional stability
Excellent flexibility
Finer line etching capability
High Peel Strength after thermal and chemical treatment
Excellent chemical durability
Manufacturing Process
1) Sputtering
Pretreatment & tie coat layer is the chief process for improving the adhesion between PET film & Cu plating layer.
2) Plating
It’s the electroplating process which is important to control the Cu plating thickness.
Structure
Properties
Storage
Cu/PET/Cu film should be stored in the original packaging at temperatures of 4–29°C (40–85°F) and below 70% humidity. The product should not be frozen and should be kept dry, clean and well protected.
Application
LED flexible light bar, radio, smart home, smart car and other fields.
