The polyimide film is typically supplied in rolls and needs to be inspected for any defects or imperfections.
Copper foil is also supplied in rolls and may undergo surface treatment to enhance adhesion.
2. Lamination:
In this step, the copper foil is laminated onto the polyimide film to create the base material for Pyralux AP9121R.
The lamination process involves applying heat and pressure to bond the copper foil and polyimide film together.
The resulting material has a uniform copper layer on one or both sides of the polyimide film.
3. Imaging:
The laminated material is then coated with a photosensitive layer known as a dry film resist.
A photomask, which contains the desired circuit pattern, is aligned and placed over the dry film resist.
The material is exposed to UV light, which transfers the circuit pattern onto the dry film resist.
4. Etching:
After imaging, the material undergoes a chemical etching process to remove the unwanted copper.
The dry film resist acts as a protective layer, ensuring that only the desired circuit pattern remains.
The etching process is typically performed using an etchant solution that selectively dissolves the exposed copper.
5. Drilling:
Holes for component mounting and interconnections are drilled into the Pyralux AP9121R material.
Precision drilling machines are used to create holes of specific diameters and locations.
The drilled holes are typically plated with a conductive material to establish electrical connections.
