    How To Manufacture A Coil PCB?

    The use of coil PCB is rapidly increasing day by day. So, you have to ensure its faultless manufacture. The basic steps of PCB coil manufacturing are explained below for you. Let’s have a look.

    PCB Design

    At the beginning of the manufacturing process, you need to design the PCB. You must consider the factors that affect the PCB design. Like the number of turns, trace width, inner radius of the coil, vias, etc. You should follow the proper guideline and choose the right dimensions during design.

    Software Operation

    After completing the design of the PCB layout, you have to check this through the design software. It assures the optimum performance of your PCB devices. You have to set the ideal output parameters properly. This helps you to verify your design.

    Component Placement

    Now, it is time to place the PCB components. You just need to ensure the maximum current flow between the PCB layers. That’s why you should try to set the component placement concerning the manufacturer’s recommendation.

    Fabrication

    This is a crucial step of the entire manufacturing process. This step combines the plating and etching of the PCB. You need to cover the vital portion of the coil PCB via the solder mask while etching.

    Sometimes, the solder wicking occurs here during the fabrication. So, you should try to avoid this issue.

    Testing

    You can apply some trustworthy testing methods to verify your PCB coil. Usually, automated optical inspection, flying probe test, function test, etc are very popular for PCB testing. That’s how you can ensure trusted manufacture of the coil PCB.

    What Are The Limitations Of Coil PCB?

    Coil PCB has a few limitations. These negative sides hamper the device’s performance in some aspects. The most significant drawbacks of this PCB are-

    • It sometimes suffers from the nonuniform induced current distribution. This issue causes damage to the device.
    • This PCB is vulnerable to parasitic capacitance. It happens due to excessive receiving of magnetic flux.
    • Its cost is relatively higher than the traditional wire coils.

    Perfect Coil PCB

    Perfect Coil PCB

    You can easily overcome these limitations through a reliable assembly of the coil PCB. We have been manufacturing this PCB for more than 15 years. Inquire us for having a trouble-free coil PCB.

    How To Test A Coil PCB Performance?

    You can achieve a clear idea about the performance of a coil PCB easily. You just need to conduct a trusted inspection of this PCB in this case. The most reliable inspection methods for performance verification are explained here.

    Automated Optical Inspection

    It is a contact-free inspection process. The AOI machine is integrated with a high-power camera. This camera scans the coil PCB and captures its images. This test identifies the quality defects of a PCB by comparing it with a perfect one.

    This automated inspection also detects catastrophic faults like the wrong placement of the components visually.  It should be applied after the reflow process to check the solder connections, fillet size, etc. The AOI test is effective and time-saving. But It costs a lot.

    Flying Probe Test

    This test is effective for high-density PCB projects. Here, you can see different probes are headed towards the different axis. The inspector makes a contact between these probes and the coil PCB.

    Then the PCB receives an electric signal and responds to it. You can detect faulty connections, improper soldering, faults in current and power rating, etc through this test.

    PCB Flying Probe Test

    PCB Flying Probe Test

    The best thing about the flying probe test is you don’t require extra fixtures to switch The PCB. Normally, a solenoid is applied to get the Z-axis direction of the probes. This inspection kills time in a high-volume PCB application. Watch this video:
