OUR PCBS
Flexible PCB
Flexible PCBs, also known as Flex PCBs or FPCs (Flexible Printed Circuits). Flexible PCBs are a type of printed circuit board that, as the name suggests, is designed to be flexible and bendable. Flexible PCBs are constructed using flexible materials like polyimide (PI) or polyester.

Characteristics &Manufacturing
Introduction to Flexible Printed Circuit Boards (FPCBs)
Flexible Printed Circuit Boards (FPCBs) are electronic circuit boards made from flexible substrates. They are designed to adapt to various spatial requirements by allowing bending, folding, and flexing. FPCBs are composed of metal foils, such as copper, and flexible polymers like polyimide. These boards are known for their lightweight, flexibility, high-temperature resistance, and excellent bending capabilities.
Manufacturing Process of Flexible Printed Circuit Boards
-
Substrate Preparation
Suitable flexible substrates, such as polyimide films, are selected and cleaned to remove surface contaminants.
-
Copper Foil Treatment
Thin-film adhesives are applied to the substrate surface, followed by the lamination of copper foils. Enhanced adhesion is achieved through processes like heat pressing or electroless copper plating.
-
Patterning
Photolithography techniques are employed to transfer the designed circuit pattern onto the copper foil, creating conductive pathways.
-
Electroplating
An electroplating process is utilized to deposit a protective metal layer, such as nickel or gold, onto the conductive pathways. This step enhances conductivity and corrosion resistance.
-
Panelization
FPCBs are cut into the desired shape based on design requirements and undergo surface treatments, including edge plating and hole drilling. Component Assembly: Electronic components and connectors are either soldered or bonded onto the FPCBs.

Component Assembly
Electronic components and connectors are either soldered or bonded onto the FPCBs.
-
Testing and Inspection
The manufactured FPCBs undergo electrical testing and reliability inspections to ensure compliance with specifications.
-
Packaging and Delivery
The finished FPCBs are packaged according to customer requirements and delivered accordingly.
