    Flex PCB Assembly – The Ultimate FAQ Guide

    A flexible PCB assembly is something you’re interested in upgrading?

    Are you planning to install rigid and flexible parts on the PCBs?

    Well, we’ve got all your questions answered!

    In the following guide, we have gathered some reasoning questions to solve all your queries.

    Let’s get right to it:

    What Is A Flex PCB Assembly?

    A flex PCB assembly is the most common type of printed circuit board assembly made rigid along with the flex materials on the other side.

    It is known as the most patterned arrangement of the circuit boards and components made up of flexible made materials.

    The flexible materials used in the construction of the flex PCB assembly are available with or without flexible coverlay.

    You can fabricate all the flexible electronic assemblies with the help of components that are made up of rigid printed circuits.

    All types of flexible circuit boards can conform to the desired shape during their application in different electric appliances.

    The cost of flex PCB assembly is slightly higher than the rigid PCB circuits because of the complexity of extensive materials and processes involved in its manufacturing process.

    However, the manufacturing steps of flexible circuits of PCB are the same as that of rigid PCB board circuits.

    The flexible circuits of PCB use stiffeners to make them slightly rigid, enabling them to work as a stable component in electrical devices.

    Flex PCB Assembly

    Flex PCB Assembly

    How Are Flex PCB Assembly Made?

    The manufacturing process of flex PCB assembly are listed as under:

    • Introduction to Material Handling

    The first step in manufacturing flexible PCB circuits is material handling since it determines the high production part yield rate and finishing of the manufactured circuits.

    Handling of the flexible PCB circuits involves the production of scrap material and coping up with reliability issues.

    All thin materials are equipped with a particular type of instrument to transport without damaging them.

    • Pad Plating

    The second step in the manufacturing of flexible PCB circuits is evaluating how and where copper must be plated on the parts of the circuits. Thus, the Pad Plating method is used in this step.

    The pad plating method corresponds to the placement of copper in the holes and similar circular areas surrounding the circuits’ parts. No additional copper is placed in this step.

    It is the most crucial step because any plated copper on the flex circuit can decline the flexibility of the circuit.

    • Polyimide Coverlay Manufacturing

    Cover lays the solid sheets of Polyimide, which are available with adhesive backing. These coverings are used to expose the SMT or PTH pads in the circuits.

    Thus, the CNC knife cutting method is used to manufacture the polyimide coverlay. After the manufacturing of Polyimide, they are positioned and laminated with the help of heat and pressure.

    Many other manufacturing rules are also included in this step, such as the feature size, shape of the board, and configuration.

    • Determination of Material Dimensional Tolerances

    All types of flexible PCB circuits are thinner than rigid boards and are available with no reinforcement. The thin layer of the flexible PCB circuits results in the dimensional stability of the materials.

    Thus, stable materials are needed for tooling or registration systems. In this step, all flexible materials will shrink when exposed to moisture or heat.

    Experts suggest using the smaller production of the panel sizes compared to the dimensions involved in mitigating material stability in rigid PCB boards.

    • Laser Profile Cutting

    It is a crucial method involved in cutting the polyimide materials with a laser. The primary reason for adopting this step is to ensure the accuracy of the complex profile.

    Besides laser technology, the routing method is also used to limit the profiles’ complexity, resulting in the ragged part’s edge.

    However, the laser cutting method will leave a small amount of carbon residue on the circuit parts, but the IPC standards deem these carbon residues.

    • Plasma Desmear

    The complex designs of flexible PCBs need an impressive desmear process and etch-back steps to ensure the reliability of the plated holes and inner layer interconnects.

    Etch back process is mainly used on rigid and flexible boards. This process causes inconsistent results in the finished parts of the PCB board circuits.

    After plasma desmear, plasma etch back is used to prefer the production of high-quality PCB circuit boards.

    How Thick Is A Flex PCB?

    A flex PCB has a thickness ranging from 0.05mm to 0.8mm.

    However, different layers present in the flex section of PCB have different thickness levels.

    The lower thickness of the flexible models of PCBs as compared to the rigid PCBs has enabled them to be used in many essential appliances.

    This lower thickness level also improves the working efficiency of the flexible circuit boards of PCBs.

    There are also multilayer flexible circuit boards of PCB which have more thickness than the estimated value.

    Thickness of Flexible PCB

    What Is Material Used In Flex PCB Assembly?

    The following materials are used in the Flex PCB assembly are listed as under:

    • Ordinary Film Substrate

    The most basic material used in constructing the flexible models of PCBs is the common film substrate because it provides the best conductor carrier capacity to the circuit board.

    It also acts as an insulator between the circuits. Besides insulation, it also makes it easy for the manufacturers to bend or curl the PCB.

    • Polyimide Substrate

    Another substrate film present in the flexible models of PCBs is the polyimide substrate. It remains flexible even after thermosetting. Thus it increases the flexibility of the circuit.

    However, the PI film is not efficiently resistant to humidity and tears, but now the upgraded PI film helps in its mitigation.

    • Adhesive Base

    In addition to all these materials, the flexible models of PCBs require an adhesive or a particular type of base that attaches its different layers.

    The manufacturers have now issued an adhesiveness PI that connects copper without any adhesive material to cope with this need.

    Material Used In Flex PCB

    Material Used In Flex PCB

    What Is The Structure Of Flex PCB Assembly?

    The structure of the flex PCB Assembly consists of the following materials.

    • Insulating Substrate Material

    This material is used with the flexible insulating film between the two layers of the flexible circuit board of PCB. Insulating substrate material acts as the primary carrier with all its mechanical and electrical performance.

    • Adhesive

    Many substrate materials are used as the primary adhesive to attach copper layers to the circuit. The use of adhesive eliminates the need for other adhesive materials.

    • Metal Conductor Layer (Copper Foil)

    A thin copper foil is integrated between the different layers of flexible circuit boards of PCB. The copper foil acts as the substantial conductor layer between the parts of the PCB.

    • Cover Layer

    The cover layer in the flexible models of PCB is made up of the highest quality of Polyimide integrated with the layers of flexible adhesive. This cover layer plays the role of the solder mask.

    In addition to the structural parts of the flexible circuit board of PCB, there are the following types of PCB flexible models.

    This type of flexible circuit of PCB has a simple structure and can easily be fabricated.

    It compromises a complex structure and offers many control difficulties.

    This type of flexible circuit board in PCB has a complex structure compared to single and double-layered PCBs.

    Some other types of PCBs based on the structural differences are:

    • Single-side rigid-flex PCB
    • Double-side rigid-flex PCB
    • Multi-layer rigid-flex PCB

    Structure Of Flex PCB

    Structure Of Flex PCB

    What Is The Flex PCB Assembly Process?

    The Flex PCB Assembly process is divided into two types:

    In this flex PCB assembly process, all parts of the flexible model of PCB are mounted directly on the surface of the flex or rigid-flex circuits,

    This method is now known as the best alternative to the assembly processes of flexible circuit boards of PCB.

    Compared to the surface mount technology (SMT) assembly, the through-hole assembly corresponds with the connection of components by soldering wire leads.

    The wire leads are embedded into the holes of the circuit board. This method is generally performed manually.

    Some other potential flex PCB assembly methods include:

    • Flip Chip Assembly Method
    • Ultrasonic Welding
    • Wire Harness
    • In-circuit Testing

    In addition to this, the positioning and consistency of the board carrier improve the quality of the PCB circuits.

    • A large Number of Panels

    They are mainly used to miniaturize electronic products, including all cell phones and digital cameras.

    Moreover, it works with a low number of components in a single circuit board. It improves the assembly and efficiency of the panels.

    • Low Density

    The low density of the flexible circuits of PCB is supported by the availability of a low number of components on the board.

    There are only two types of connectors that work with not more than 50 components.

    • High Product Quality

    The repetitive bending and control accuracy of PCB circuit boards meet the demands of their applications in the environment.

    The high-quality cleanliness and anti-static precautions, and soldering reliability is ensured in the flexible models of the PCB as compared to the rigid PCBs.

    • High Assembly Cost

    The cost of the flex PCB assembly is a bit higher than the rigid types of PCBs because of a wide range of fixture applications.

    In addition to the application fixtures, the more extended manufacturing and low equipment utilization rates are responsible for high assembly costs.

    • Flip Chip Assembly

    In this assembly method, the components are directly bonded to the substrate of the flexible circuit board of PCB.

    • Ultrasonic Welding

    The ultrasonic welding works by producing a weld by the local application of high-frequency vibratory energy.

    • Wire Harness

    It uses the cable harness or wiring assembly for producing the systematic and integrated arrangement of cables within the circuit.

    • In-Circuit Testing

    This testing method is used to carry out electrical probe tests of the populated printed circuit board for eliminating the causes of short circuits.

    • X-Ray Inspection

    This inspection method is used to identify the corrosion under insulation by using the non-destructive inspection method of radiography.

    • Pressure Sensitive Adhesives (PSAs)
