    Stack up

    PCB stack-up is an important factor in determining the EMC performance of a product. A good stack-up can be very effective in reducing radiation from the loops on the PCB, as well as the cables attached to the board.

    Four factors are important with respect to board stack-up considerations:

    1. The number of layers,

    2. The number and types of planes (power and/or ground) used,

    3. The ordering or sequence of the layers, and

    4. The spacing between the layers.


    Usually not much consideration is given except as to the number of layers. In many cases the other three factors are of equal importance. In deciding on the number of layers, the following should be considered:

    1. The number of signals to be routed and cost,

    2. Frequency

    3. Will the product have to meet Class A or Class B emission requirements?

    Often only the first item is considered. In reality all the items are of critical importance and should be considered equally. If an optimum design is to be achieved in the minimum amount of time and at the lowest cost, the last item can be especially important and should not be ignored.

    The above paragraph should not be construed to mean that you can’t do a good EMC design on a four- or six-layer board, because you can. It only indicates that all the objectives cannot be met simultaneously and some compromise will be necessary. Since all the desired EMC objectives can be met with an eight-layer board, there is no reason for using more than eight layers other than to accommodate additional signal routing layers.

    The standard pooling thickness for multilayer PCBs is 1.55mm. Here are some examples of multilayer PCB stack up.

    Metal Core PCB

    A Metal Core Printed Circuit Board (MCPCB), or a thermal PCB, is a type of PCB that has a metal material as its base for the heat spreader portion of the board. The purpose of the core of an MCPCB is to redirect heat away from critical board components and to less crucial areas such as the metal heatsink backing or metallic core. Base metals in the MCPCB are used as an alternative to FR4 or CEM3 boards.


    Metal Core PCB Materials and Thickness

    The metal core of the thermal PCB can be aluminum (aluminum core PCB), copper (copper core PCB or a heavy copper PCB) or a mixture of special alloys. The most common is an aluminum core PCB.

    The thickness of metal cores in PCB base plates is typically 30 mil - 125 mil, but thicker and thinner plates are possible.

    MCPCB copper foil thickness can be 1 - 10 oz.


    Advantages of MCPCB

    MCPCBs can be advantageous to use for their ability to integrate a dielectric polymer layer with a high thermal conductivity for a lower thermal resistance.

    Metal core PCBs transfer heat 8 to 9 times faster than FR4 PCBs. MCPCB laminates dissipate heat, keeping heat generating components cooler which results in increased performance and life.
