Multilayer Rigid-Flex PCB

Multilayer Rigid Flex PCB Description

Multilayer Rigid Flex PCB is a printed circuit board with multiple circuitry layers. Multilayer flexible PCB uses PI or PET as the substrate. Like rigid multilayer PCBs, multilayer laminate technology makes multilayer FPC. The simplest multilayer flexible PCB is a three-layer flexible PCB formed by covering two copper shielding layers on both sides of a single-sided flexible PCB. This three-layer flexible PCB is equivalent to a coaxial wire or shielded to a wire in electrical performance. The most commonly used multilayer flexible PCB structure is a four-layer structure, which uses metalized holes to realize interlayer interconnection. The middle two layers are generally the power layer and the ground layer.


A Multilayer Flex Circuits combine several single-sided or double-sided circuits with complex interconnections, shielding and/or surface mounted technologies in a multi layer design. The Multilayer Flex Circuits may or may not be continuously laminated together throughout the production process. If your design needs require maximum flexibility, continuous lamination may not be appropriate. Multilayer Flex Circuits are an effective solution when confronted with design challenges such as: unavoidable crossovers, specific impedance requirements, elimination of crosstalk, additional shielding and high component density.


Multilayer Flex Circuit is proud to be able to say that “We Go Where Others Will Not” when it comes to helping you with design solutions utilizing multilayer flex circuits.

Double-Sided Rigid-Flex PCB

Multilayer flexible printed circuits feature three or more layers of conductors separated by a dielectric, usually polyimide, in which the internal conductors can be interconnected by way of plated through-holes.


As in the previous flex family members, covercoats may be used on one or both sides.While the number of conductor layers designed into this type of flex are limitless, package size, layer count vs. flexibility must be considered during design layout to ensure ease of installation.Typical multilayer flex circuits range from 3 to 6 layers of conductor.


We can manufacture all kinds of difficult Multilayer Rigid-Flex boards, including step structure Rigid-Flex PCB, flying tail structure Rigid-Flex PCB, layered flexible PCB, non-layer edilexible PCB and multilayer rigid-flex pcb, and etc. Of all types of PCBs, Multilayer Rigid-Flex PCB is the most resistant to harsh application environments, so it is favored by manufacturers of industrial control, medical andmilitary equipment.

Double-Sided Rigid-Flex PCB

Rigid-Flex PCB is a new kind of printed circuit board with both durability of rigid PCB and adapt-ablity of flexible PCB.

Rigid-flex PCB is derived by bonding two rigid outer on flexible PCB.The circuit of the rigid layer and flexible layer are connected by metalzed hole.

As a connective device, the primary benefits of Multilayer Rigid-Flex compared to traditional cabling and rigid boards include

1. Reduced wiring errors

2. Elimination of mechanical connectors

3. Unparalleled design flexibility

4. Higher circuit density

5. More robust operating temperature range

6. Stronger signal quality

7. Improved reliability and impedance control

8. Size and weight reduction


When to use Multi-Layer Flex

1. Required when circuit density and layout cannot be routed on a single layer

2. Ground and power plane applications

3. Used for shielding applications

4. Dense surface mount assembly

5. Increased circuit density

6. Controlled impedance with shielding


Multilayer Flex Pcb Features
