    What Is The Quality Control Process Of Rigid-flex 14 Layer PCB?

    Rigid-flex 14 layer PCB makes the electric circuits compatible with different fields. It offers supreme flexibility along with adequate rigidity in electronic devices. The rigid-flex feature is essential to turn this circuit board stretchable and bendable.

    Its quality control is the combination of a series of work. You need to give proper attention to material selection, testing, handling, etc to maintain this top-class multilayer PCB.

    PCB Materials

    PCB materials used in a 14 layer PCB fabrication have a great impact on its quality control. These materials should have stable electronic characteristics. Such as low relative permittivity, high dielectric strength,  high transition temperature, etc.

    Component Sourcing 

    It is required to ensure the component sourcing from a reliable supplier. Besides, you must consider the component’s shelf life, UL rating, ingress protection rating, mounting process, etc while selecting components for 14 layer circuit boards.

    Regular Maintenance

    You can achieve a standard quality of this PCB if it goes through regular maintenance.  You should inspect it at a regular interval to find out the defects.

    Functional Test

    A proper functional test provides the real behavior of a 14 layer PCB. If you want to be sure about its real-time performance in high vibration and thermal pressures, a functional test is a good process. You can get the opportunity to promote the quality by resolving the defective issues.

    Proper Use

    The quality of a multilayer PCB hampers due to its wrong use in most cases. You should follow the manufacturer’s guide while handling and storing a 14 layer PCB. Besides, don’t keep this circuit board in extreme heat.

    Though it can tolerate extreme temperatures, this is not suitable for maintaining supreme quality. It damages the functionality and resistive power of the PCB materials.

    How To Maintain Impedance Stability In A 14 layer PCB Design?

    Impedance stability is a vital issue in 14 layer PCB manufacturing. That’s why you should take care of electrical and mechanical properties that influence impedance in PCB layers.

    Impedance in the PCB transmission line depends on the following factors:

    • Dielectric constant
    • Dielectric thickness
    • Copper thickness
    • Trace width
    • Temperature change

    A low and stable dielectric constant (DK) is necessary for achieving impedance control in an electric circuit. So, you need to use the PCB materials which offer a stable DK value (3.6-6.0).

    Again, lower dielectric thickness and wider trace width ensure sufficient insulation in the PCB layers of the 14 layer PCB stackup. These properties are also crucial for having a stable impedance.

    Frequent temperature change is a harmful measure for this PCB.  It causes drastic fluctuations in the electric properties of PCB materials. This results in high impedance and inhibits the current transfer between the PCB layers.

    You need to constantly maintain a proper dimension to achieve the desired impedance value. Otherwise, you never maintain the quality of your electronic appliances. Watch this video to get a better idea about controlled impedance PCB routing:

     

    Which Component Mounting Is Ideal For High-frequency 14 Layer PCB?

    A 14 layer high-frequency PCB usually supports both surface mount technology (SMT) and through-hole technology (THT). You need to choose the suitable component mounting carefully. 14 layer PCB assembly offers the flexibility to the manufacturers to apply a required mounting process as per their requirement.

    SMT is preferable to those applications where you need to ensure supreme durability and smooth signal transmission. This component mounting process is used in a maximum 14 layer circuit board assembly. Surface mount devices offer effective component connections with low maintenance costs.

    Besides, SMDs are reputable for their commendable resistance against oxidation and mechanical stresses. These components are supportive of miniature designs. So, you can enjoy a lightweight circuit board by applying SMT.

    On the contrary,  THT is comparatively less-used in 14 layer PCB assembly. It is mainly applicable where extreme robustness is required. But, it is highly expensive compared to SMT. You should decide on your project’s demand.
