MATERIAL OF 6 LAYER FLEXIBLE PCB

6 layer flex PCBs use high-quality materials to ensure top performance, durability, and flexibility. Here’s what we use:

Polyimide (PI):

  • Role: Primary substrate material.
  • Properties: Polyimide offers excellent thermal stability, flexibility, and mechanical strength. It withstands high temperatures, making it perfect for harsh environments. Its flexibility allows the PCB to bend and conform to complex shapes without cracking or breaking.

Adhesive Materials:

  • Types: Acrylic-based or epoxy-based adhesives.
  • Properties: These adhesives bond the layers of the PCB together. They provide strong adhesion while staying flexible. Acrylic-based adhesives resist heat and chemicals. while epoxy-based adhesives offer high strength and durability.

Copper Foil:

  • Role: Conductive layers.
  • Properties: High-purity copper foil ensures excellent electrical conductivity for signal transmission. The copper layers enhance adhesion to the substrate and prevent oxidation.

Coverlay:

  • Material: Polyimide or polyester films.
  • Role: Protective layer over the copper traces.
  • Properties: The coverlay protects the copper traces from moisture, dust, and mechanical damage. It also provides insulation and maintains the flexibility of the PCB.

Protective Coatings:

  • Types: Solder mask, conformal coating.
  • Properties: These coatings protect the PCB from oxidation, corrosion, and short circuits. The solder mask, made of epoxy or polyimide, covers everything except the solder pads. providing insulation and protecting the copper.

Stiffeners:

  • Material: FR4, Polyimide.
  • Role: Reinforcement in certain areas.
  • Properties: Stiffeners add mechanical support and rigidity in specific areas of the flex PCB. FR4 (fiberglass epoxy laminate) and polyimide provide strength while maintaining some flexibility.

6 LAYER FLEX PCB MANUFACTURING PROCESS

flexible pcb board manufacturing process-design

Step1: Design and Material Selection:

The first step is to design the circuit and determine the specific requirements for the 6 layer flex PCB. This includes deciding on the number of layers. stack-up configuration, trace routing, component placement, and material selection.

Step2: Material Preparation:

The chosen flexible substrate material, typically polyimide. That supplied in rolls or sheets and undergoes a cleaning process. to remove any contaminants that could affect the bonding. or adhesion of subsequent layers.

Step3: Copper Cladding

The polyimide sheets coated with a layer of copper. This involves laminating a thin layer of copper foil. onto the polyimide surface using heat and pressure. The copper etched to remove excess material, leaving behind the desired copper traces.

Step4: Imaging and Etching

A photoresist applied to the copper layer. and the circuit pattern transferred onto it using a photomask and UV exposure. The exposed areas are then chemically etched. removing the unwanted copper, and leaving behind the desired circuit traces.

Step5: Drilling and Plating

Small holes called vias drilled through the polyimide. and copper layers at specific locations to provide interconnections between different layers. The vias are then plated with a conductive material. such as copper or electroless nickel to ensure electrical continuity.

Step6 : Lamination

The individual layers, including the conductive layers and insulating layers. stacked together and laminated under heat and pressure. An adhesive layer, often made of epoxy, Used to bond the layers together. This process forms a 2-layer structure with the desired stack-up configuration.

Step7 : Coverlay Application

A coverlay, which is a protective layer made of polyimide, applied on top of the circuitry. It bonded to the flexible PCB using heat and pressure. The coverlay protects the circuit traces from environmental factors and provides insulation.

Step 8 : Surface Finishing

The exposed copper pads on the outer layers plated with a surface finish. such as electroless nickel immersion gold (ENIG). to protect them from oxidation and facilitate soldering during assembly.

Step 9 : Testing and Inspection

The manufactured 2 layer flexible PCB undergoes testing and inspection. to ensure it meets the required specifications and quality standards. This includes electrical testing, impedance measurement, visual inspection. and possibly other specific tests depending on the application.

Step 10 : Assembly and Integration

The completed 2 layer flex PCB is then integrated into the electronic device or assembly. Components soldered onto the board. and any additional mechanical or electrical connections made as necessary.
