Type of flexible circuit board

1. Single panel
After the completion of the circuit, the single-sided PI copper clad plate material is used to cover a layer of protective film to form a flexible circuit board with only a single layer of conductor.
2. Ordinary double-sided board
After the completion of the double-sided circuit, a layer of protective film is added to the two sides of the double-sided PI copper plate material to form a circuit board with double-layer conductors.
3. Single panel generated by base plate
In the circuit manufacturing process, using pure copper foil material, a protective film is added on both sides of the circuit respectively to form a circuit board with only a single layer of conductor but exposed on both sides of the circuit board.
4. Base plate generates double-sided board
Two layers of single-sided PI copper-coated sheet material are used in the middle of which is supplemented by the adhesive with a window opening at a specific location to form a double-sided conductor circuit board with a two-layer separation structure in the local area, so as to achieve a circuit board with high flexibility in the layered area
