Layer Stacking:

The flexible PCB can have single or multiple layers. depending on the complexity of the circuit design. Adhesive layers used to bond multiple layers together.

Etching and Patterning:

The copper layer on the flexible substrate etched. to create the desired circuit traces and pads following the circuit design.

Drilling and Plating:

Holes drilled in the flexible PCB for component mounting and interconnection between layers. These holes are then plated to ensure electrical continuity.

Coverlay Application:

Coverlay, which is a protective layer of polyimide or solder mask applied over the circuitry. to protect it from environmental factors and mechanical stress.

Component Assembly:

Surface-mount and/or through-hole components assembled onto the flexible PCB. using specialized assembly equipment and techniques.

Testing:

The flexible PCB undergoes rigorous electrical testing. to verify its functionality and adherence to design specifications.

Cutting and Forming:

Once the flexible PCB tested, it cut and formed according to the required shape and dimensions for the specific application.
