3、 Manufacturing process 3、 Manufacturing process

The manufacturing process of blind hole FPC is relatively complex, mainly including the following steps:
Inner layer circuit fabrication: Inner layer circuits are fabricated on the substrate, and predetermined circuit patterns are formed through processes such as photolithography and etching.
Blind hole drilling: Use high-precision drilling equipment to drill blind holes at the desired location. This step requires precise control of the depth and position of the borehole to ensure that the blind hole can be correctly connected to the specified inner circuit.
De drilling and metalization: After drilling, there will be some impurities such as drill cuttings and oil stains remaining on the hole wall, which need to be treated for de drilling. Afterwards, metallization treatments such as electroless copper plating and electroplated copper are carried out to form a conductive layer on the walls of blind holes.
Layering and Outer Circuit Manufacturing: Layering multiple layers of materials together and creating conductive circuits on the outer layer. This step requires ensuring tight bonding between layers and stable electrical performance.
Surface treatment and cover film bonding: Apply anti-oxidation treatment to the surface of the circuit board and bond the cover film at designated locations to protect the circuit.
Molding and Inspection: Cutting, bending, and other molding processes are carried out on circuit boards, and strict quality inspections are conducted to ensure that they meet design and usage standards.
