Double-Sided Flexible PCB

The KunXiang Double-Sided Flexible PCB (DFCB) is a type of circuit board that features conductive traces on both sides of a flexible substrate. It inherits the advantages of traditional Flexible Printed Circuit Boards (FPCs) such as lightness, flexibility, and high-density wiring, while further enhancing circuit integration and wiring efficiency through the double-sided design.

Key Features

Double-Sided Wiring: The DFCB allows for more complex and intricate circuit designs by incorporating conductive traces on both sides of the flexible substrate.

High-Density Wiring: With wiring on both sides, the DFCB significantly increases wiring density, reducing board area and saving space.

Excellent Electrical Performance: The DFCB exhibits excellent electrical conductivity and insulation properties, meeting the demands of various complex circuits.

High Reliability: Utilizing advanced production techniques and materials, the DFCB offers superior durability, including resistance to bending, abrasion, and extreme temperatures, ensuring stable operation in harsh environments.

Flexibility: The DFCB can be bent, folded, or twisted to adapt to irregularly shaped devices.

The production of the Double-Sided Flexible PCB typically involves the following steps:

Substrate Preparation: Selecting the appropriate flexible substrate material, such as polyimide (PI) or polyester (PET).

Circuit Design: Designing the conductive trace patterns for both sides of the circuit based on specific electrical requirements.

Circuit Fabrication: Applying printing, etching, and other processes to create the conductive traces on the substrate.

Coverlay Application: Applying a protective coating over the conductive traces to enhance durability and reliability.

Performance Testing: Conducting electrical performance and reliability tests on the completed DFCB to ensure product quality.
