Our custom Flex PCB manufacturing capabilities allow us to develop and produce a top-performing flex PCB that meets your unique requirements.
Flex PCB Base Materials
Base material Polyimide DuPont PI, Domestic Shengyi PI, base material polyimide thickness of 12, 25, 50, 75 and 125 microns are available standards are 25 & 50 microns.
copper weight of 9,12,18, 35 and 70 microns are available on one or both sides
Coverlay polyimide thickness of 12, 25, 50, 75 and 125 microns are available standards are 25 & 50 microns with the adhesive thickness of 12, 25 and 50 microns. FR4 & polyimide Stiffeners from 0.050mm to 2.400mm or higher.
Often application require support in areas where connectors or components are applied, most materials can be uses as a stiffener, the most common being FR4, polyimide or polyester with thickness from 0.050mm to 2.400mm. Stiffeners can be bonded using a high temperature pressure sensitive tape or a thermal setting adhesive. Holes in stiffeners should be 0.015” larger than the hole in the flexible to allow for registration. The position of the stiffener should overlap the coverlay by a minimum of 0.030” so there is no common ending, this will remove the potential for stress and cracking

Flex PCBs Defined
A Flex Circuit or Flex PCB is a patterned arrangement of printed circuitry and components that utilizes flexible based material with or without flexible coverlay. These flexible electronic assemblies may be fabricated using the same components used for rigid printed circuit boards, but allowing the board to conform to a desired shape (flex) during its application
Static Application – An application where flexible circuits are flexed only to install the circuit and fit it into its application (also known as flex-to-fit or flex-to-install). A static application will typically be made using the less expensive Electro Deposited (ED) copper.
Dynamic Flexing Applications – A situation where the flexible circuit itself is dynamically (repeatedly) flexed during the actual use of the final product. Common examples include flip-type cell phones, laptops, printer heads and robotic arms. A dynamic application will require the use of Rolled Annealed (RA) copper.

Some Benefits of Flex PCBs
Because of the advantages (for example, cost, space, and weight savings) that flexible and Flex Rigid PCB have for some projects, they are used ever more frequently. Multi-CB can produce your flexible circuit boards with the highest quality, either as prototype or as series.
Saving Space: Flex PCB design requires only about 10 percent of the space and weight of a wired circuit board assembly, offering greater installation and packaging freedom. The inherent flexibility also permits tighter bend capabilities.
Maximum Reliability: A flexible printed circuit board requires fewer interconnects, which in turn require fewer contact crimps, connectors and solder joints. Simply put, a FPCB does not contain as many potential sources for failure, which enhances their reliability.
Enhanced Capabilities: The flexible PCB is compatible with virtually any type of connector or component and works well with options such as ZIP connectors. They also perform extremely well in extreme temperatures and offer superior resistance to radiation and chemicals.
Cost Savings: Cost-saving advantages of flexible printed circuits include reduced material and packaging requirements, lower parts replacement costs and a reduction in assembly errors that could otherwise result in the need for repairs.
All of these benefits make flex circuit boards ideally suited for a wide range of applications in industries such as Military, Transportation, Medical, Consumer Electronics, Automotive, Aerospace, Communications and Industrial.
