Rigid Flexible PCB Fabrication Process

1. Cutting: Cutting of hard board base material: Cut a large area of ​​copper-clad board into the size required by the design.

2. Cutting the flexible board base material: Cut the original roll material (base material, pure glue, covering film, PI reinforcement, etc.) into the size required by the engineering design.

3. Drilling: Drill through holes for circuit connections.

4. Black hole: Use potion to make the toner adhere to the hole wall, which plays a good role in connection and conduction.

5. Copper plating: Plate a layer of copper in the hole to achieve conduction.

6. Alignment exposure: Align the film (negative) under the corresponding hole position where the dry film has been pasted to ensure that the film pattern can correctly overlap with the board surface. The film pattern is transferred to the dry film on the board surface through the principle of light imaging.

7. Development: Use potassium carbonate or sodium carbonate to develop the dry film in the unexposed areas of the circuit pattern, leaving the dry film pattern in the exposed area.

8. Etching: After the circuit pattern is developed, the exposed area of ​​the copper surface is etched away by the etching solution, leaving the pattern covered by the dry film.

9. AOI: Automatic optical inspection. Through the principle of optical reflection, the image is transmitted to the equipment for processing, and compared with the set data, the open and short circuit problems of the line are detected.

10. Lamination: Cover the copper foil circuit with an upper protective film to prevent circuit oxidation or short circuit, and at the same time function as insulation and product bending.

11. Laminating CV: Press the pre-laminated covering film and reinforced plate into a whole through high temperature and high pressure.

12. Punch: Use the mold and the power of the mechanical punch to punch the work plate into the shipping size that meets the customer's production requirements.

13. Lamination (superposition of rigid-flex pcb boards)

14. Pressing: Under vacuum conditions, the product is gradually heated, and the soft board and hard board are pressed together through hot pressing.

15. Secondary drilling: Drill the via hole connecting the soft board and the hard board.

16. Plasma cleaning: Use plasma to achieve effects that conventional cleaning methods cannot achieve.

17. Immersed copper (hard board): A layer of copper is plated in the hole to achieve conduction.

18. Copper plating (hard board): Use electroplating to thicken the thickness of hole copper and surface copper.

19. Circuit (dry film): Paste a layer of photosensitive material on the surface of the copper-plated plate to serve as a film for pattern transfer. Etching AOI wiring: Etching away all the copper surface except the circuit pattern, etching out the required pattern.

20. Solder mask (silk screen): Cover all lines and copper surfaces to protect the lines and insulate.

21. Solder mask (exposure): The ink undergoes photopolymerization, and the ink in the screen printing area remains on the board surface and solidifies.

22. Laser uncovering: Use a laser cutting machine to perform a specific degree of laser cutting on the position of the rigid-flex junction lines, peel off theflexible board part, and expose the soft board part.

23. Assembly: Paste steel sheets or reinforcements on the corresponding areas of the board surface to bond and increase the hardness of important parts of the FPC.

24. Test: Use probes to test whether there are open/short circuit defects to ensure product functionality.

25. Characters: Print marking symbols on the board to facilitate the assembly and identification of subsequent products.

26. Gong plate: Use CNC machine tools to mill out the required shape according to customer requirements.

27. FQC: The finished products will be fully inspected for appearance according to customer requirements, and defective products will be picked out to ensure product quality.

28. Packaging: The boards that have passed the full inspection will be packed according to customer requirements and shipped to the warehouse.
