    Multilayer Printed Circuit Boards

    Millennium Circuits Limited is a leading supplier of multilayer printed circuit boards, which are more complex and have a variety of differences from the standard single- and double-sided PCBs.

    Multilayer printed circuit boards have at least three layers of conductive material, set right in the middle with multiple other layers stacking on this core. In many cases, these other layers are copper foil, but as a smart multilayer PCBs supplier, MCL can work with you to support a large array of materials.

    Experience With Custom Multilayer PCBs

    MCL is a pioneer manufacturer of multilayer PCBs, and we have extensive experience with customers using these boards across multiple applications and industries. We can ensure that your boards are built to the tightest of standards, whether you need a simple epoxy glass support or want to move into the exotics with Teflons or ceramics.

    Multilayer Printed Circuit Board Process

    Manufacturing multilayer circuit boards starts by creating the PCB core.

    Prepreg layers — made of the same material as your core — are added next. These layers are not fully cured, so they can be adjusted and processed more than the core.

    Foil is then added, and can be alternated with additional prepreg layers, through a lamination process. We’re an established manufacturer of multilayer PCBs, so we rely on the latest pressure and high-temperature techniques to ensure that the boards are properly fused and the prepreg layers are safely melted to join all of the layers.

    Benefits of Multilayer PCBs

    The entire curing process used to manufacture multilayer printed circuit boards creates a unified, extremely tough, solid multilayer board. This delivers a variety of benefits:

    • Considerable space savings
    • EMI shielding with ground and power layers
    • High assembly density
    • More flexible boards
    • Reduction of the need for interconnection wiring
    • Simpler incorporation with impedance features


    Multilayer PCB suppliers like MCL have provided boards for an extremely wide range of industries and applications. Here are just a few highlights of where you’ll find work done by a proud manufacturer of multilayer PCBs:

    • Atomic accelerators
    • Cellular transmitters and repeaters
    • Computers
    • Data servers and storage technology
    • Fiber optics
