Product Details

Double-Sided Rigid-Flex PCB

Double Sided Printed Circuit Boards offer two conductor layers separated by a dielectric, usually polyimide. Coverlayers may be used on one or both sides. Plated through holes may or may not be featured to interconnect traces on opposite sides of the dielectric.Double Sided Printed Circuit Board provides the ability to access circuit traces from both the top and bottom sides of the circuit offering greater flexibility in design and functionality.

Properly designed and utilized, Double Sided Printed Circuit Boards offer the same level of dynamic flexing (repetitive movement) as do single-sided flex, providing a much wider range of application uses due to its ability to carry more complex circuit layouts.

We focus on the field of Flex Printed Circuit Board more than 20+ years,and we have ISO9001 quality management system certification,rosh,ISO14001 environmental management system certification,TS16949 automobile quality management system certification and other certification.

Double Sided Printed Circuit Board PCB

We can manufacture all kinds of difficult Flex Printed Circuit Boards and Rigid Circuit Boards , including step structure Rigid-Flex PCB.flying tail structure Rigid-Flex PCB.layered flexible PCB,non-layer edilexible PCB, etc.

Of all types of PCBs,Flex Printed Circuit Boards and Rigid Circuit Boards is the most resistant to harsh application environments, so it is favored by manufacturers of industrial control, medical and military equipment.

Double Sided Printed Circuit Board PCB

Rigid Circuit PCB Board is a new kind ofprinted circuit board with bothdurability of rigid PCB and adapt-ablity of flexible PCB.

Rigid Circuit PCB Board is derived by bonding two rigid outer on flexible PCB.The circuit of the rigid layer and flexible layer are connectedby metalzed hole.

Double Sided Flex Pcb

double sided flex circuit is a circuit having two conductive layers, one on each side of the base layer of polyimide within the circuit. Trace patterns, specific to your needs, can be created on both sides of the substrate film and can be connected where desired with copper plated through-holes. The plated through holes make electrical connections between the two layers.

When to use Double-Sided Flex

  • Required when circuit density and layout can not be routed on a single layer

  • Ground and power plane applications

  • Used for shielding applications

  • Dense surface mount assembly

Double-Sided Features

  • Component assembly available on both sides

  • Two conductive layers

  • Can be converted into a Sculptured Flex

Benefits of Double-Sided Flexible Printed Circuits:

  • Wider circuit design parameters when compared to single-sided flex

  • Access to circuit traces from both sides of the flex configuration

  • Reduced assembly costs due to minimized interconnect errors

  • Dynamic flexing ability

  • Neater/cleaner system appearance

  • Reduced packaging dimensions

Double sided Flex Application

  • Double-Sided Flex can be used in:

  • Ground and power plane applications

  • Dense surface mount assembly

  • Shielding applications

  • LCD Module for Mobile Phones

  • Digital Cameras

  • Optical Pick-up for AV and Computers

There are many benefits to Flexible Printed Circuits including:

Assembly Error Reduction – With accurate designs and automated production, flex circuits eliminate human errors once involved in hand-built wire harnesses. With the exception of production-induced errors, circuits are ONLY routed to those points called for by the accurate design plan.

Decreased Assembly Time and Costs – Flex circuits require less manual labor during assembly and reduce production errors. Flex circuits have an intrinsic ability to integrate form, fit and function. Flex circuits eliminate the high cost of routing, wrapping and soldering wires. Complete interconnection systems are installed or replaced, rather than individual hard PC boards. As a result, wiring errors are eliminated and hence manufacturing costs are reduced. Whether it is a low volume production with a complex circuit or high volume production with a simple circuit, assembly time and costs are decreased.

Design Freedom – Unlike rigid boards, flex circuits are not restricted to two dimensions. Because they are as flexible as wires or ribbon cables, flex circuit design options are endless. At Flexible Circuit, we pride ourselves on taking on the most complex of design challenges. Flex circuits can be designed to meet highly complex and unimaginable configurations while being able to operate in the most hostile environments. Flex circuit designs could entail any of the following:

  • Highly complex configurations

  • Withstand hostile operating environments

  • Single- Double- combinations

  • Complex interconnections

  • Shielding

  • Rigid/flex capabilities

  • Surface mounted devices
