Features
- Reverse treated copper foil
- Low profile, with high peel strength
- The treated foil is pink
- As reverse-treated copper foil, this product has better etchability
performance. It can effectively shorten the production process,
achieve higher speed and fast micro-etching, and improve the
conformance rate of PCBs.
Typical Application
- High frequency, Ultra -high frequency, applying to PPE board
- Fine circuit pattern
- It is mainly applied in multilayered boards and high-frequency
boards.
