Single-Sided FPCB, Double-sided FPCB, Multilayer FPCB, and Rigid-Flex FPCB
To manufacture different types of flexible printed circuit boards (FPCBs), various equipment and processes are involved. Here’s a general overview of the equipment typically used for manufacturing single-sided FPCBs, double-sided FPCBs, multilayer FPCBs, and rigid-flex FPCBs:
- Single-Sided FPCB:
- Substrate Cutting Machine: Used to cut the flexible substrate (usually polyimide or polyester) into desired shapes and sizes.
- Imaging/Exposure Equipment: Used to transfer the circuit pattern onto the substrate through a photosensitive film or dry film resist.
- Etching Machine: Used to chemically remove unwanted copper from the substrate, leaving behind the desired circuit pattern.
- Plating Equipment: Used for copper electroplating to enhance the copper thickness and ensure good conductivity.
- Solder Mask Coating Machine: Used to apply a protective solder mask layer over the copper traces, leaving only the desired areas exposed for soldering.
- Surface Finishing Equipment: Used for applying a final finish to the exposed copper surfaces, such as hot air leveling (HASL), immersion gold, or immersion tin.
- Double-Sided FPCB:
- Same equipment as for single-sided FPCBs, with the addition of the following:
- Drilling Machine: Used to drill holes for component leads and vias to establish electrical connections between the two sides of the board.
- Electroless Copper Deposition System: Used for depositing a thin layer of copper inside the drilled holes, forming the conductive vias.
- Multilayer FPCB:
- Same equipment as for double-sided FPCBs, with the addition of the following:
- Lamination Press: Used to bond multiple layers of flexible substrates together with adhesive layers.
- Bonding Press: Used for bonding inner layers of the FPCB stack with copper foils.
- Laser Drilling Machine: Used for high-precision drilling of microvias in the multilayer stack.
- Copper Plating Line: Used for through-hole copper plating and subsequent copper buildup on the outer layers.
- Additional Imaging/Exposure, Etching, and Plating Equipment: Required for the outer layer circuits.
- Rigid-Flex FPCB:
- Same equipment as for multilayer FPCBs, with the addition of the following:
- CNC Milling Machine: Used for precise cutting and shaping of the rigid sections.
- Z-axis Registration System: Ensures accurate alignment between the rigid and flexible sections during lamination.
- Additional Drilling and Plating Equipment: Required for the rigid sections.
Please note that specific equipment may vary depending on the manufacturer’s capabilities, technology requirements, and production scale. The above list provides a general idea of the equipment commonly used for manufacturing different types of FPCBs.
