    What Is FR2 PCB Assembly?

    FR2 PCB assembly is the procedure of attaching electrical components to the printed circuit board’s wirings. PCBs include traces, or conductive paths etched into the laminated sheet layers of copper that are used to build the assembly.

    Before using a fully operating electronic device, the last step is to attach the electrical parts to the FR2 PCB.

    You should give attention to detail and extreme accuracy as they are essential for FR2 PCB assembly. Assembling electrical devices using FR2 PCBs may be done in three ways:

    SMT (Surface Mount Technology)

    Many PCB assembly businesses are presently using a technology first established in the 1960s and refined in the 1980s. Metal tabbed PCB components are used in the process, which makes soldering PCBs easier. When parts are soldered on both edges of the PCB, the approach allows for larger circuit density.

    SMT Assembly Of FR2 PCB

    SMT Assembly Of  FR2 PCB

    Plated Through-hole

    Leads are joined to components in this procedure. There are holes punched into the FR2 PCBs required for this type of construction. The leads have been successfully placed into the drilled holes, it is now easier to integrate the PCBs with the parts.

    Mechanical-electrical Assembly

    This assembling PCBs with electronic components utilizes wire harnesses, looms, bespoke metalwork, wire assembly, and molded plastics.

    What Are The Design Considerations For FR2 PCB?

    When it comes to FR2 PCB layout and design, there is a lot to consider. While some concerns apply to the whole process, others are more focused on a single stage. This board is so sensitive that you must be very careful while handling it. The following are the most important considerations.

    Board Limitations

    The initial limits to consider are those of the bare board. The board’s size and form are examples of fundamental restrictions. Ensure you have enough board space for the circuit. The board’s size is determined by the final product’s size and usefulness.

    Manufacturing Techniques

    Consider the manufacturing procedures you want to use to make the board. Methods have restrictions and constraints.

    Materials and Parts

    During the layout process, examine the board’s parts and materials. Make sure the requested things are accessible first. Some materials and components are scarce, while others are prohibitively costly. Take your time choosing the best materials for your FR2 board and designing a board highlighting their capabilities.

    Component Order

    The basic PCB design principle is component placement order. Connectors come first, followed by power circuits, precision circuits, crucial circuits, and the remainder of the components.

    Orientation

    When arranging components, attempt to align them in the same orientation. This will speed up the soldering process and reduce errors.

    Placement

    Keep items that will sit below plated through-hole pieces away from the solder surface of the FR2 PCB.

    What Is The Manufacturing Process Of FR2 PCB?

    A well-manufactured FR2 PCB promotes the device quality to a great extent. Its entire manufacturing is a lengthy work that is divided into various parts. You need to maintain supreme quality in each step of manufacturing for optimizing this circuit board.

    Now, we are going to explain all the steps of an FR2 PCB manufacturing process for your convenience.

    PCB Layout Design

    First, you need to draw a schematic of this PCB. It is the outline of your circuit board design. Then, design the PCB layout by using reliable design software. Nowadays, various design software is used in designing FR2 circuit boards.

    Then, you have to convert this design file into Gerber format. The Gerber file contains all the required information related to PCB manufacturing. Besides, it is important to conduct a design rule checking for finding faults in the design.

    After completing the checking, send the file to the manufacturer to handle the further steps.

    Printing

    In this stage, the FR2 circuit board laminate needs to wash. Then, it receives the photoresist that is composed of photoreactive chemicals. A UV-ray is dropped upon this board to perform the printing process.

    After preparing, the circuit board should be washed with proper liquid.

    Initial Etching

    Etching means eliminating unwanted copper from the PCB laminate. Here, the FR2 PCB board covered with photoresists goes through a copper solvent bath. Then, the unmasked coppers get washed.

    FR2 PCB Manufacturing

    FR2 PCB Manufacturing

    Alignment of PCB Layer

    After a successful primary etching, it is required to align the PCB layers. An automated optical inspection can be run for checking this layer alignment and other features of this PCB.

    Binding Of Layers

    In this segment, you need to bind PCB layers. The outer PCB layers should be connected to the substrate.

    PCB Drilling

    Now, it is time to drill holes on the stack PCB board. Here, maintaining the hole diameter and drilling speed concerning the shape of PCB components is essential. Usually, an X-ray is used in finding the proper placement of drilling.

    Copper Coating

    After drilling, a copper coating is applied to fill up the drilled holes. Besides, plating binds the layers together. Then, image the external PCB layers by applying photoresists once again.

    Final Etching

    Then, the board is placed in a toxic Ferric Chloride solution. It reduces unwanted coppers again. In this case, you must cover the necessary portions through a protective mask.

    Watch this video to know more about etching:

    Application Of Solder Mask

    In this stage, cover the board with solder mask ink. Then, apply a solder mask on both sides of the FR2 circuit board.

    PCB Surface Finish

    Surface finish is a reliable technique for improving solderability and protecting the PCB surface from corrosion. In this part, a suitable metal is coated on the copper layer according to the requirement of electronic devices.

    Assembly Testing

    In the end, an electrical test along with a functional test is conducted. It ensures an error-free Fr2 circuit board assembly. Then, the last thing is cutting the circuit board from the panel.

    This is the basic manufacturing process of FR2 PCB. You can find some variations concerning the consumer’s demand.

    How Do You Mount The Components On FR2 PCB?

    You can mount PCB components on FR2 PCB Through two popular mounting technologies. These are-

    • Surface Mount Technology (SMT)
    • Through-hole Technology (THT)

    SMT deals with surface mount devices. It is convenient for a designer to place these components in compact designs that lead to a miniature application. It ultimately makes the device lightweight.

    Besides, surface mount technology provides tremendous robustness to the components. That’s why SMDs offer supreme mechanical stability under high temperatures and vibrations.

    Moreover, components can be placed on both sides of the FR2 circuit board in this case. So, it is widely used in high-density FR2 PCB projects.

    On the contrary, THT is applicable for PCB components having leads. Here, these components are placed on the surface by using drilled holes. After completing the insertion properly, you need to solder the components by applying THR (Through-hole Reflow) or wave soldering.

    THT promotes the durability and thermal resistivity of the FR2 PCB board. Again, through-hole components are compatible with both prototype PCBs and advanced designs.

    SMT And THT In PCB Assembly

    SMT And THT In PCB Assembly

    But, the FR2 circuit board supports SMT more than THT because of its improved reliability and high rate of component placement. Moreover, the drilling process increases the cost of THT.

    That’s why surface mount technology has better uses for mounting components in FR2 PCB assembly. The following video will help you to know more about component soldering in PCB:

    How Does FR2 PCB Compare To FR1 PCB?

    FR2 PCB and FR1 PCBs have numerous similarities in terms of specifications and performance. But, these two circuit boards have a disparity in multiple issues. We are here with a comparative analysis between these PCBs. Let’s have a look.

    Improved Insulation

    FR2 circuit boards offer improved insulating properties in electronic products. FR2 materials ensure sufficient dielectric strength in the circuit board designs. So, this PCB is capable of carrying higher current loads.

    But, the dielectric strength of FR1 PCB materials is not supportive of improving insulation in many cases.

    Reliability

    In terms of reliability, FR2 circuit boards are better than FR1 PCBs due to their signal integrity. This PCB is less vulnerable to electromagnetic interference, noise, etc issues that hamper the reliability of a PCB.

    On the other hand, FR1 circuit boards suffer from noise while transferring data to the receiver end. In this case, FR2 PCB delivers improved performance compared to FR1 PCB.

    Easy Maintenance

    The maintenance of this circuit board is easy and costs low. FR1 PCB maintenance cost is comparatively higher than the PCBs composed of FR1 materials.

    Through-hole Technology

    Both of these PCBs are not supportive of through-hole technology for component mounting. But, you can apply THT in the FR2 circuit board assembly.

    Glass Transition Temperature

    FR1 materials offer higher glass transition temperature (130⁰C) than FR2 PCB materials. They deliver more impressive thermal performance. FR2 is a standard TG material. Its TG is around 105⁰C. So, the thermal management of FR2 circuit boards is not similar to FR1 PCB.

    FR2 Vs FR1 PCB

    FR2 Vs FR1 PCB

    What Are The Differences Between FR2 PCB And FR4 PCB?

    FR4 is the most used PCB material in the electronic world. FR2 PCB is not as highly effective as FR4 PCBs. But, this PCB is preferable to those applications where manufacturing cost is a crucial factor.

    If you look for temperature resistance in PCB materials, FR4 is the best option. But, FR2 materials provide adequate thermal resistivity in some applications. Besides, Fr4 materials improve the quality of multilayer PCB designs to a large extent.

    Their dielectric strength, moisture absorption rate, etc properties are supremely impressive. That’s why these PCB materials have profound applications in different electronic sectors.

    FR4 PCB

    FR4 PCB

    FR2 PCB specifications are also commendable. But these features do not always match the quality of FR4 materials. But, their low-cost feature makes it desirable to the low-volume PCB manufacturer.

    How To Choose The Right Manufacturer Of FR2 PCB?

    Usually, FR2 PCBs are applicable in single-layer designs in most cases. To ensure the optimum output of this circuit board, you need to choose the right manufacturer. But, it is not so simple to find a trustworthy PCB manufacturer in China.

    You should keep in mind the following issues if you intend to make a good choice for FR2 PCB manufacturing.
